00:00:00Black stripes on yellow school buses aren't an element of design.

00:00:04They're actually metal rails put along the sides and the back of the bus to protect its rather thin walls.

00:00:10In case of a collision, they absorb most of its force. It means that the crash doesn't affect large areas.

00:00:17These rub rails are also positioned in strategically important spots.

00:00:21The lowest one runs at the floor level, the middle one matches the bottom of the seats, and the top one

00:00:27corresponds either to the top of the seats or the bottom of the window.

00:00:33Your ceiling fan can move in more than one direction for a reason. One is for summer, the other for winter.

00:00:39When the weather is hot, ceiling fans should move counterclockwise.

00:00:43This makes them pull the warm air up and push the cold air down. And the clockwise, winter mode,

00:00:50moves the warm air down and raises the cool air.

00:00:54As soon as you notice the blue bristles on your toothbrush start fading, it's a sure sign it's time to replace it.

00:01:02You can adjust your stapler so that it staples documents together only temporarily.

00:01:07It's done by rotating the crimp area. Most staplers have two options for stapling. One is standard,

00:01:14but the other side bends staples away from the center. Later, when you don't need them anymore, you can easily remove them by hand.

00:01:23Lots of people use a knife to remove strawberry stems, but this way they throw away a lot of stuff

00:01:29they could otherwise eat. Instead of a knife, use a regular drinking straw.

00:01:34Insert one end of the straw into the bottom of the strawberry and push it gently all the way through.

00:01:40If everything goes as planned, the straw will pop the stem out.

00:01:45A tiny hole in a padlock bottom helps to drain the water from an outside lock after the rain.

00:01:50It prevents the thing from rusting and clogging.

00:01:53You can also use this hole to oil the lock's hinges so that it doesn't get stuck.

00:01:58If a lock doesn't have this small hole, you should only use it inside.

00:02:04It's a bad idea to place dirty dishes covered in mashed potatoes or any other

00:02:09leftover carbs closer to the sides of the bottom shelf of your dishwasher.

00:02:14Several studies have shown that such plates get washed better when you put them in the middle of the rack.

00:02:20So now you know.

00:02:22Weird markings on the bottom of a toothpaste tube have nothing to do with the ingredients.

00:02:27They're actually there for the factory robots.

00:02:29Not so they can brush their own teeth either. Such a colorful square marks the line where the tube has to be cut and folded.

00:02:38Now, most cotton pads have two different textures on each of their sides. One surface is firmer and more absorbent.

00:02:45It's supposed to be used with nail polish remover.

00:02:48The other side is way finer and softer. You should use it to remove facial and eye makeup.

00:02:55Don't peel post-it notes off from the bottom.

00:02:58It'll create a crease in the paper, and the note won't stick well after that. Tear it off from the side, and it'll stick longer.

00:03:07When driving when it's already dark,

00:03:09you might get blinded by the headlights of the car moving behind yours.

00:03:13If you have a manual rear-view mirror,

00:03:15find a tab at the bottom and flip it. The mirror has a reflective material behind its glass.

00:03:21By flipping the tab, you change the angle of this material, dimming the lights in the mirror.

00:03:27The whole process is even simpler if you have a power mirror. All you need to do is switch on the nighttime mode.

00:03:35Bath foam relieves stress, cleanses the skin, and keeps the water warm.

00:03:40Foam is made up of tiny air bottles. They form an insulating layer on the water surface, keeping the heat from escaping.

00:03:49Let's say you're reading a paper book.

00:03:51Then you decide to take a break and realize you don't have a bookmark. Should you leave a dog ear?

00:03:58You don't need to. That's what the dust jacket is for.

00:04:02Apparently, providing you with the information about the book and its author isn't its only purpose.

00:04:08Your stomach growls, and suddenly a peanut butter sandwich sounds like a great idea.

00:04:14You open a jar and see quite a lot of oil sitting on the top.

00:04:19Duh! Time to train your arm muscles and stir, stir, stir.

00:04:23But if you store peanut butter jars upside down, the oil will move to the bottom and all the solids will be on top.

00:04:32The main purpose of the drawer under your oven isn't to store all those pots and pans.

00:04:38You're supposed to use this place to keep your food warm while something else is being prepared in the oven.

00:04:45If you don't have anywhere to put a toothpick after using it,

00:04:49snap off the flat end at the first groove and put it on the table.

00:04:53Now you can balance the used part of your toothpick on the grooved part, so it doesn't have to touch the table.

00:05:01The correct way to break off a piece of Toblerone chocolate bar is by pushing the pointy side downward.

00:05:07Me? I just bite it off, but then I'm hardly ever accused of being correct.

00:05:13Most extension cords are known to come undone at even the slightest pull.

00:05:19Loosely tie them together, and they'll stay connected even if you accidentally pull on them.

00:05:23The knot might get tighter, but nothing will get switched off.

00:05:28A little groove on the bottom of a cup lets cool air get underneath it.

00:05:33It saves glassware from cracking when a scorching beverage heats it up.

00:05:38And when you place cups upside down in the dishwasher, the groove prevents water from gathering in the cup's bottoms.

00:05:46Non-stick pans have a special coating, which makes them so great.

00:05:50But if you use metal utensils while dealing with such a pan, you're likely to scratch this coating.

00:05:56And once you do it, your pan is ruined.

00:05:59Food will stick to its surface and end up burned or unevenly cooked.

00:06:06Make your life brighter and get a BrightSide D. Pick your own print, just follow the link below.

00:06:11If you've always peeled bananas, starting from the stem, try doing it the other way round.

00:06:17Pinch the bottom of the banana and pull. This way, you don't have to deal with strings and mess.

00:06:23By the way, that's the approach monkeys use. And you don't want to argue with monkeys.

00:06:30Most caps on small tubes are hollow on top and have a little spike inside.

00:06:35Its purpose is to break the foil sticker sealing the tube.

00:06:39The neck of the tube fits right in this hole, and the spike is designed to break the seal.

00:06:44No need to struggle trying to tear the tiny foil seal off with your fingers.

00:06:49The more detergent you use, the cleaner your clothes are, right?

00:06:53Not exactly. If you add too much detergent, you can spoil your things.

00:06:58This will produce too many suds, and your clothes won't be rubbing against one another.

00:07:03And that's exactly what helps them get clean.

00:07:06Excess suds can also keep your washing machine from rinsing properly.

00:07:11Book pages are often printed on large sheets of paper, rather than on small individual ones.

00:07:17If there isn't enough content to fill these sheets, there are blank pages left.

00:07:22Publishers often print the words notes or leave some other signs on them.

00:07:27This way readers don't think it's a printing mistake.

00:07:31The rumble strips on the side of the road are supposed to wake up sleepy drivers

00:07:35who start to doze off behind the wheel.

00:07:37When your tires drift off onto these strips, the noise and vibration work like an alarm clock.

00:07:44It's a popular misconception that pumping a mascara wand back and forth

00:07:49allows more product to stay on it.

00:07:51In reality, doing this will only spoil your mascara.

00:07:55By moving the wand, you push air inside the tube.

00:07:59This not only produces flakes and clumps, but also makes the mascara dry out.

00:08:05A dime-sized hole in the elevator doors is a keyhole.

00:08:09If the doors get stuck, an operator can open them manually by inserting a special key in this hole.

00:08:15The same tool is used when an elevator needs routine maintenance.

00:08:20The bubbles in your soda push the straw up when they balance the buoyancy with the mass of the straw.

00:08:26But you can keep your straw from rising in your soda can by putting it through the hole in the metal pull ring.

00:08:32Ah, the science behind soda cans!

00:08:36Those squares of fabric that come with clothes are for you to try out your cleaning products on them first.

00:08:42This way, you won't ruin the entire item once you decide to wash it.

00:08:47The soft round part under a soda bottle cap keeps the bubbles from escaping.

00:08:52Without it, your pop would go flat in no time, probably even before you buy it.

00:08:57And what's worse, if you bought the flat drink for your dad, then your pop's pop won't pop.

00:09:05The utility knife is supposed to last way longer than most people think.

00:09:09The knife blade is made of narrow parallel sections.

00:09:12When the instrument gets blunt, break off the top section with the cap you can find at the bottom.

00:09:18Voila, you have a brand new sharp blade again!

00:09:21But don't forget to put on a pair of safety gloves and goggles before doing this.

00:09:26Yes, it's another sharp tip from Bright Side!

00:09:32Okay, today I'll show you things you've never seen and tell you stuff you never knew.

00:09:37Wow, all in one video, what a bargain!

00:09:40For example, these soda fountain stations in fast food restaurants.

00:09:44We all see the nice side of it, but have you ever wondered where all this soda comes from?

00:09:49Let me take you behind the scenes.

00:09:51Ta-da!

00:09:52Turns out it's a pile of boxes with tubes.

00:09:55So, when the drink runs out, the employees change the box and plug the tube back in.

00:10:00Okay, let's peek into a couple more places where we normally don't belong.

00:10:06This is, for example, what you will see if you cut the screen of a Mac open.

00:10:11And here's what's hidden behind the dryers in a public laundromat.

00:10:15Today, 4 out of 5 households in the US have a dryer.

00:10:19But they weren't so widely accessible when they first appeared in the 1950s

00:10:23because they were way too expensive for the average homeowner.

00:10:27Now, grocery shopping isn't an uncommon practice,

00:10:30and we all have walked past dairy fridges a million times.

00:10:33But have you ever wondered what's behind them?

00:10:35Turns out they're just shelves, and store employees stack the products from the other side.

00:10:40It makes perfect sense, but I never imagined it like this.

00:10:44Now, this photo shows what's behind the elevator button.

00:10:47Obviously, a bunch of cords.

00:10:49The buttons are all wired to a computer that manages the elevator.

00:10:53How does the computer know where the elevator is at a particular time?

00:10:57Well, there are several possible systems,

00:11:00but the most common one is a long vertical tape in the shaft with a series of holes.

00:11:05A sensor counts the number of holes that are passed,

00:11:08and that's how the location is determined.

00:11:11Okay, there are a couple of common things we all know,

00:11:15but the purpose of which remains a mystery to most.

00:11:18So let me share these secrets with you.

00:11:21Those metal rivets on jeans have been there from the very beginning.

00:11:25Jacob Davis, the iconic man who made the first pair of jeans,

00:11:29added copper rivets to places where pants are most likely to rip.

00:11:33Today, they have more of a decorative and distinctive purpose

00:11:37since they are a traditional attribute of the jeans everyone knows of.

00:11:41Now, I'll bet you know there are extra loops on some shoes.

00:11:45No, they're not for sweat or ventilation.

00:11:48Those are extra loops for laces, just like other loops you use.

00:11:51But they're there to tie your shoe around the ankle to prevent your foot from moving aside.

00:11:57That's especially helpful if you're hiking and ascending and descending hills and trails.

00:12:02Now, have you ever noticed those half-belt thingies many coats and jackets have at the back?

00:12:07Turns out they first appeared on oversized military jackets,

00:12:11so the extra fabric could be collected on the back,

00:12:14and the person doesn't stumble when working.

00:12:17Today, those belts are only added for the sake of style and tradition.

00:12:21Most clothing items you buy come with a small bag of fabric or a button, or both.

00:12:26These are actually not useless.

00:12:29Buttons obviously can be replaced if you lost the original one.

00:12:32Pieces of fabric can serve two purposes.

00:12:35You can patch up the hole, but the main purpose is to provide you with a sample of cloth

00:12:40so you can use it to test different washing products on it and see what happens to the fabric.

00:12:46Now, pom-poms on woolen hats.

00:12:49Did you know that sailors were wearing hats with pom-poms in the 18th century

00:12:53to protect their heads in case they accidentally whacked them?

00:12:56Regular people were wearing them in Scotland,

00:12:59and the color of the pom-pom signified the person's social status.

00:13:03People got back to wearing hats with those cute decorative items during the Great Depression.

00:13:07They're made of sparry yarn, so it was a cheap way to decorate your hat.

00:13:12Now, if you haven't noticed, some sidewalks have little plates with bumps on them.

00:13:17Most people don't pay much attention to them,

00:13:20but they're very important for visually impaired people.

00:13:23It signals a slope that then leads to a crosswalk.

00:13:27Also, several patterns signal different things.

00:13:30Have you noticed that the icon of a gas tank on car dashboards has a little arrow next to it?

00:13:36Well, the arrow has a purpose.

00:13:38It points at the side of the car where the gas tank is located.

00:13:42Very useful for forgetful people, like me, who constantly wonder which side it is on,

00:13:47and also for those who drive rentals once in a while.

00:13:50The answer is right in front of your eyes.

00:13:53If you can't find the arrow on your panel,

00:13:55then the fuel hose on the icon indicates the side instead.

00:13:59Now, on the back of many makeup and hygiene products,

00:14:03you'll find this symbol with a marking like 6M, 12M, and 24M.

00:14:08This is the number of months this product can serve you before you should toss it out.

00:14:13You might know that whistles work perfectly fine

00:14:16even if they don't have that ball inside.

00:14:18And yet, they have it, but why?

00:14:21Even though there's a sound without the ball,

00:14:23the noise it creates is very flat, and it's not distinguishable enough.

00:14:28When the whistle has a ball inside,

00:14:30then it starts moving with every blow,

00:14:32indicating different pitches and making the noise more noticeable.

00:14:36Lollipop sticks have those squared holes on the end of their sticks for a reason, too.

00:14:42When the candy is put on the stick,

00:14:44some of it goes into the hole, fixating the candy part.

00:14:48This way, the candy ball or whatever shape is less likely to fall off the stick.

00:14:53Yeah, it's a bummer when that happens.

00:14:55Measuring tapes have that little metal stud on the end.

00:14:59Most people know that you can use it to stick it to the side of the surface you're measuring.

00:15:03But it's not the only cool thing about it.

00:15:06Look, there's also a small slot,

00:15:08and this slot can be used to hang it on a nail,

00:15:11again to free your hands and keep measuring.

00:15:14The bottom of the end of the tape has a ridged edge.

00:15:17It'll help you make a mark if you don't have a marking tool with you.

00:15:21Have you ever wondered why the tape's blade is curved?

00:15:24Well, it helps to keep it rigid when extended.

00:15:27Pay a closer look at the blade.

00:15:30Apart from numbers and markings, there are also black diamonds.

00:15:34Those are there every 12.2 inches,

00:15:37and they're useful for construction workers to space engineering joints.

00:15:41They can also be useful for you if you want to hang something heavy, for example.

00:15:45The diamond will mark the exact center of a stud

00:15:48which is placed 16 inches apart from one another.

00:15:51And you can drill something to that center

00:15:54to make sure whatever you hang is safely attached.

00:15:57Now, most coins have ridges,

00:16:00and this is the legacy of the olden days.

00:16:03You see, back in the day, all coins were linked to a silver standard.

00:16:07The amount of silver used in a coin was proportionate to the value of the coin.

00:16:12So, the more actual silver was used to make the coin,

00:16:15the higher its value was.

00:16:17Hi-ho, silver!

00:16:19Do you remember the Lone Ranger?

00:16:21Silver was the name of his horse.

00:16:23Never mind.

00:16:24Anyway, all the coins had precious metal in them,

00:16:27and some people started shaving off a little bit of silver from it.

00:16:31It wasn't noticeable on one,

00:16:33but if done on several,

00:16:35people could get quite a bit of that precious metal.

00:16:38So, to prevent fraud,

00:16:40the edges were made with ridges for security reasons.

00:16:43So, if someone attempted to shave it off,

00:16:45the ridges would disappear,

00:16:47and no one would accept that coin anymore.

00:16:49Smart!

00:16:50Today, no one makes coins out of silver,

00:16:53the coins just represent the value.

00:16:55But the ridges are kind of a cultural heritage now.

00:16:58And finally, a typical plastic milk jug

00:17:01often has inverted circles on one or more of the sides.

00:17:05Like alien crop circles,

00:17:07this dimple is there to make the jug more resistant

00:17:10and to prevent it from erupting in case the jug falls on the floor.

00:17:14The dimple gives some more space for the liquid to expand.

00:17:17Also, as the expiration date approaches,

00:17:20the microbes in the milk start to expel some gases.

00:17:23As there are more of them trapped inside,

00:17:25the pressure in the jug is rising.

00:17:27The dimple takes care of the expansion

00:17:29and prevents the jug from exploding.

00:17:32And the cows are utterly delighted

00:17:34that their hard work is not wasted.

00:17:39If you ever find yourself stuck in the trunk of your car,

00:17:42stay calm.

00:17:43All cars are supposed to be equipped with an emergency latch

00:17:46to help open the trunk from the inside

00:17:49in the unlikely case it happens.

00:17:51These latches are so well thought out

00:17:53that they can be opened by people of all ages.

00:17:56More so, handles are designed to glow in the dark too.

00:17:59You can even pull them with the mouth

00:18:01if there's not enough wiggle room to use your hands.

00:18:04Never mind how you ended up in the trunk in the first place.

00:18:07Moving on.

00:18:08If you're ever working with needle and thread,

00:18:11remember you don't need to stick the needle

00:18:13directly into the spool.

00:18:15You may end up losing the needle altogether.

00:18:17Not to mention you can easily hurt your fingers.

00:18:20A lot of modern sewing kits these days

00:18:22come with a designated place for safeguarding the needles.

00:18:26It's located at the bottom part of the thread spool.

00:18:29You'll just need to pull it out.

00:18:31It's even made to hold multiple sewing needles at a time.

00:18:34Disposable ballpoint pens come with a little secret of their own.

00:18:38Did you ever notice that in some of them

00:18:40there's a small hole in the plastic part?

00:18:43It's actually a rudimentary ventilation system.

00:18:46It's supposed to let the ink easily make it to the tip of the pen.

00:18:50Okay, I know it's in the name,

00:18:52but you really don't need to shake the seasoning shaker

00:18:55to get any product out.

00:18:57Don't believe me?

00:18:58Hey, you're not the only one.

00:19:00Go grab your favorite seasoning bottle out of your pantry.

00:19:03If it has one of those removable plastic caps,

00:19:06it's perfect for the experiment.

00:19:08Instead of shaking the bottle,

00:19:10try holding it from the plastic cap

00:19:12while it's upside down.

00:19:14Now gently twist the bottle from side to side

00:19:17and, before you know it,

00:19:19you get some gorgeously flowing seasoning

00:19:22without having to wiggle the shaker

00:19:24and make a mess all over the stove.

00:19:26On the same note,

00:19:28most salt and pepper shakers

00:19:30should have ridges on the bottom of the glass portion.

00:19:31In case you get any seasoning stuck in there,

00:19:34place the bottom of the salt shaker

00:19:36against the bottom of the pepper shaker

00:19:38and wiggle it around

00:19:40so the ridges click with each other.

00:19:42The seasoning should easily pour out now

00:19:44without you having to open the bottle.

00:19:46In colder weather,

00:19:48you often have so many clothing layers on you

00:19:50that you can hardly feel the purse

00:19:52or back straps on your shoulder anymore.

00:19:54Not to mention how fast they can slide off.

00:19:57Some jackets come with a built-in solution for that

00:20:00in the form of a small tab on the shoulder

00:20:03with either a hook or a button.

00:20:05It's meant to be opened and closed comfortably

00:20:08so you can keep your purse in place at any time.

00:20:12You're most likely using it

00:20:14merely to peel the skin of potatoes,

00:20:16carrots, or cucumbers.

00:20:18But you can use your vegetable peeler

00:20:20for chopping fine strips of onion as well.

00:20:23Just cut the onion into quarters vertically

00:20:25and then start slicing.

00:20:27This might also help out

00:20:29with those embarrassing onion tears.

00:20:31Most people miss this one,

00:20:33but should you ever have a closer look

00:20:35at your toothpaste tube,

00:20:37you will surely see some sort of coloring there,

00:20:39either a dot or a block.

00:20:41Colors can vary.

00:20:43They can be black, green, red, or even blue.

00:20:46These color spots are actually meant

00:20:48to help the assembly machines

00:20:50back at the toothpaste factory.

00:20:52They recognize when and where these machines

00:20:54need to cut the toothpaste tubes

00:20:56and proceed to fold them for packaging.

00:20:59For most types of footwear,

00:21:01if there's anything that seems a bit out of place,

00:21:03always know that it's there for a reason.

00:21:06Most manufacturers don't put extra items

00:21:08on shoes just for fun.

00:21:10It would definitely be a waste of time and resources.

00:21:13For footwear like boots, for example,

00:21:16there's often a small loop at the top back of the shoe.

00:21:19It's there to help you when you need to put the shoe on

00:21:22since you can quickly pull on it.

00:21:24Plus, you can also hang the shoes somewhere,

00:21:26most likely to dry,

00:21:28since those boots are meant to be worn

00:21:30in the colder weather.

00:21:32Now, I've been guilty at least once

00:21:34of overdressing with a bunch of layers

00:21:36just so I won't need to jam everything

00:21:38in my check-in bag.

00:21:40But does it become a problem

00:21:42when you actually have to get seated?

00:21:44What do you do with your coat or your jacket?

00:21:46Well, have a closer look next time

00:21:48you board a plane on the seat in front of you.

00:21:51The hook that keeps the tray table upright

00:21:53can double as a jacket hook.

00:21:55As long as you don't need to have any meals

00:21:57while in the air, you're good to go.

00:22:00Now, most mascaras expire

00:22:02within 3 to 6 months, I'm told,

00:22:04depending on the manufacturer.

00:22:06But you can help speed up that process

00:22:08if you're not careful enough.

00:22:10Continuously pumping the mascara wand,

00:22:12trying to mix in the product,

00:22:14actually pushes more air into the tube.

00:22:17This can make it dry much faster,

00:22:19and you evidently won't get

00:22:21the desired results with it anymore.

00:22:23There's an easy way to check

00:22:24if your mascara is still good enough to use.

00:22:27If you don't hear a popping noise

00:22:29when you take the brush out,

00:22:31you may very well need to go

00:22:33get yourself a new mascara tube.

00:22:35Now, I know we're living in the era

00:22:37of Bluetooth-connected devices,

00:22:39but for better quality sound,

00:22:41they still recommend using headphones

00:22:43that connect via audio jacks.

00:22:45Remember seeing black ridges on those jacks?

00:22:48They aren't there just to make them fit

00:22:50when you plug them into your phone or laptop.

00:22:53They're made out of a special insulating material.

00:22:56These bands are meant to guard the wires

00:22:58when sound is being transmitted.

00:23:00Based on the number of bands,

00:23:02you can figure out which end goes where.

00:23:04Some empty space under noodles in a cup

00:23:07doesn't mean the company producing them

00:23:09wants to cheat you out of a full portion.

00:23:11No, no.

00:23:13It's a manner of keeping the noodles intact

00:23:15during their transportation.

00:23:17It also helps with the circulation of hot water

00:23:19that is poured over the products

00:23:21before you can enjoy them.

00:23:23The neckline was initially designed

00:23:25to serve a bunch of objectives.

00:23:27First, as a way of prolonging the life

00:23:29of the garment that would maintain

00:23:31its shape over the years.

00:23:33It's also there to fit your head through the shirt

00:23:35in case it needs some stretching.

00:23:37This way, it ensures a snugger grip

00:23:39around the neck.

00:23:41Lastly, it helps absorb sweat

00:23:43in case you're wearing the shirt while exercising.

00:23:46Now, it's not necessarily a custom anymore,

00:23:48but you may have stumbled upon a dinner jacket

00:23:51with an additional mysterious pocket

00:23:53on the right side.

00:23:55Turns out, this pocket was used by men

00:23:57to easily reach their train tickets

00:23:59since most of them had to travel

00:24:01to work every day.

00:24:03It helped them keep their jacket buttoned up,

00:24:05but also benefited from the use of a pocket.

00:24:08Now, it's only added as a decoration

00:24:10and it doesn't serve an actual purpose anymore.

00:24:13Speaking of things we don't use these days,

00:24:16or at least for their initial purpose,

00:24:18did you know Play-Doh was originally

00:24:20a cleaning product?

00:24:22In the 1920s, the market was in need

00:24:24of a product that could help them

00:24:26wipe the wallpapered areas

00:24:28around coal-burning furnaces.

00:24:30The recipe for what we now know

00:24:32as Play-Doh was thus invented.

00:24:34It was manufactured in white only

00:24:36and was supposed to clean wallpaper

00:24:38by being rolled back and forth

00:24:40over the dirt.

00:24:42It was only later, in the 1940s,

00:24:44that new products for cleaning wallpaper

00:24:46were brought up,

00:24:48and Play-Doh was redirected

00:24:50toward another area of the market.

00:24:52Now, while I enjoy a nice piece of toast

00:24:54for breakfast, isn't it pesky

00:24:56to have to clean out the toaster?

00:24:58Well, not anymore,

00:25:00since I recently found out

00:25:02that toasters have a slide

00:25:04or a panel at the bottom

00:25:06that helps get rid of all those

00:25:08annoying breadcrumbs easily.

00:25:10Now, there used to be a time

00:25:13when you could only have access

00:25:15to video games by inserting cartridges

00:25:16into a console of choice.

00:25:18These tiny objects gave many doctors

00:25:20a lot of headaches.

00:25:22People soon started popping up

00:25:24in hospitals after swallowing

00:25:26small game cartridges,

00:25:28especially the younger generation.

00:25:30Nintendo, the company that manufactures

00:25:32the majority of these devices,

00:25:34had to come up with a creative solution

00:25:36to prevent these accidents.

00:25:38So, these days, Nintendo Switch cartridges

00:25:40are purposely coated

00:25:42with specific chemicals

00:25:44that can leave a really bad

00:25:46aftertaste.

00:25:48Not that I'd, you know,

00:25:50recommend you ever try

00:25:52and taste for yourself.

00:25:54Have you ever wondered

00:25:56what these extra holes

00:25:58at the top of your running shoes

00:26:00are for?

00:26:02They're designed so that

00:26:04you can tie the shoes

00:26:06in multiple different ways.

00:26:08That's useful when you want

00:26:10to compensate for things

00:26:12such as a bad stride

00:26:15or when you want

00:26:17to compensate for

00:26:19the fact that your shoes

00:26:21don't fit your feet.

00:26:23So, if you want to compensate

00:26:25for the fact that your shoes

00:26:27don't fit your feet,

00:26:29you can use these extra holes

00:26:31at the top of your running shoes.

00:26:33They're designed so that

00:26:35you can tie the shoes

00:26:37in multiple different ways.

00:26:39That's useful when you want

00:26:41to compensate for things

00:26:43that are bad.

00:26:45So, if you ever want

00:26:47to compensate for

00:26:49the fact that your shoes

00:26:51don't fit your feet,

00:26:53you can use these extra holes

00:26:55at the top of your running shoes.

00:26:57They're designed so that

00:26:59you can tie the shoes

00:27:01in multiple different ways.

00:27:03That's useful when you want

00:27:05to compensate for

00:27:07the fact that your shoes

00:27:09don't fit your feet.

00:27:12It's something called

00:27:14a Faraday shield.

00:27:16And it's there to prevent

00:27:18microwaves from getting away

00:27:20and turning the entire room

00:27:22into a Faraday cage.

00:27:24If the microwaves escape,

00:27:26your meal won't cook properly either.

00:27:28So, yep, the cage is not there

00:27:30to make it difficult for you

00:27:32to see your meal while it's cooking.

00:27:34It's keeping the

00:27:36electromagnetic energy inside.

00:27:38How about a wrench-compatible screwdriver?

00:27:40You can increase its torque.

00:27:42That's why the head of your screwdriver

00:27:44is designed the way it is.

00:27:46When you have odd angles,

00:27:48you can use this strategy.

00:27:50You've probably heard those myths

00:27:52the blue side of the eraser

00:27:54can erase the pen.

00:27:56False.

00:27:58Its purpose is to erase a pencil.

00:28:00But in case you're writing

00:28:02something on heavier paper,

00:28:04the blue side can remove

00:28:06smudges you see after using

00:28:08the pink eraser too.

00:28:10Do you know that

00:28:12most of the food you eat

00:28:14comes in the red mesh bag?

00:28:16It's a trick to make this

00:28:18food look more orange

00:28:20and encourage you to make a purchase.

00:28:22An extra tip.

00:28:24Don't throw away the mesh bag.

00:28:26Tie it up so you can have

00:28:28a small pot scrubber

00:28:30to clean your sink,

00:28:32kitchen, appliances and dishes.

00:28:34You can see golf balls

00:28:36don't have a perfectly round shape.

00:28:37At one point, experienced golfers

00:28:39started noticing how through time

00:28:41older balls with imperfections

00:28:43such as nicks and bumps

00:28:45could travel further.

00:28:47Such things create turbulence

00:28:49in the air around the golf ball

00:28:51which eventually reduces drag.

00:28:53So manufacturers

00:28:55started producing balls with dimples

00:28:57so they could go farther and faster.

00:29:01You might have noticed that sometimes

00:29:03there are ridges in toothpick tops.

00:29:05It's more hygienic because

00:29:07if you take that off,

00:29:09you can prop the toothpick up on it

00:29:11and it won't touch anything.

00:29:13Another safety feature you'll find,

00:29:15this time in your car,

00:29:17is a tab on your rearview mirror.

00:29:19With it, you can change

00:29:21the position of the mirror

00:29:23so you don't get blinded

00:29:25if there's a car behind you

00:29:27with its high beams on.

00:29:29So this little tab helps you control

00:29:31the glare of lights coming from behind.

00:29:33This feature showed up in the 1930s

00:29:35but in the early 1970s

00:29:37it was used as equipment

00:29:39in most trucks and cars.

00:29:41Do you see that tiny hole

00:29:43on your iPhone

00:29:45right next to the rear-facing camera?

00:29:47It's a microphone

00:29:49and it's there so your phone

00:29:51can record sound

00:29:53as you turn your camera around.

00:29:55Some cables have a thick cylinder

00:29:57towards the end of the cord.

00:29:59It's called a ferrite core

00:30:01or a choke.

00:30:03It's a magnetic iron oxide

00:30:06For example,

00:30:08you know that annoying static noise

00:30:10you get if you bring your phone

00:30:12too close to a speaker?

00:30:14This interrupts your call

00:30:16which is why cable cords

00:30:18with big cylinders are pretty useful

00:30:20because they prevent these things.

00:30:22Do you know why nearly all luggage bags

00:30:24and backpacks have two zippers?

00:30:26It's way more convenient

00:30:28and easier to open in that way.

00:30:30But not just that,

00:30:32you can also lock these two zippers together

00:30:34to keep your bags safer.

00:30:36You know how toilets

00:30:38at public spots like malls

00:30:40have those big gaps at the bottom?

00:30:42It's primarily

00:30:44for better circulation of air.

00:30:46This type of door also makes it easier

00:30:48to clean the toilet

00:30:50or check if it's occupied

00:30:52if you're standing in line.

00:30:54Other than that,

00:30:56if you get stuck there

00:30:58and the lock gets broken,

00:31:00you still have a way to escape.

00:31:02Have you ever noticed those plastic end caps

00:31:04on utility knives?

00:31:06And they also have scales on them

00:31:08which indicates you may use them

00:31:10multiple times but with sharp edges.

00:31:12You can separate the blades

00:31:14through these plastic end caps.

00:31:16Then you can move the slider

00:31:18and bring the sharp blade to the front.

00:31:20If you've ever taken a moment

00:31:22to examine a regular grocery cart,

00:31:24especially their fold-out section,

00:31:26you probably noticed

00:31:28those metal loops jutting out.

00:31:30They're designed to protect

00:31:32the items you carry in your cart.

00:31:34You can use them

00:31:36to hang bags with soft items.

00:31:38You don't want to accidentally

00:31:40squish with heavier products

00:31:42like bread

00:31:44or easily breakable things

00:31:46like eggs.

00:31:48Many coffee mugs come

00:31:50with curved notches on their bottom.

00:31:52When you're washing your mugs,

00:31:54put them against the rack

00:31:56at an angle in your dishwasher.

00:31:58This way, the water won't pool

00:32:00into the dishwasher.

00:32:02If you're a McFlurry fan,

00:32:04you've probably noticed

00:32:06there's a square hole

00:32:08in the handle of the spoon.

00:32:10It's there so you can attach it

00:32:12to the special machine

00:32:14that mixes the ice cream

00:32:16and your favorite toppings together.

00:32:18The machine has a bar

00:32:20that slips into this square-shaped spoon

00:32:22and then thoroughly stirs it.

00:32:24And you get the spoon

00:32:26so they can minimize the mess

00:32:28during the process.

00:32:30There's a dent on one side.

00:32:32Some might see it

00:32:34as a random design decision,

00:32:36but a dent has several purposes.

00:32:38One of them is to get bigger

00:32:40if there's a gas buildup.

00:32:42This happens when your milk is spoiled.

00:32:44So you don't even have to try

00:32:46to check this out.

00:32:48Also, the dent is there

00:32:50so the jug doesn't burst

00:32:52if you accidentally drop it.

00:32:54The dent allows the expansion space

00:32:56that deals with the sudden pressure

00:32:58Dental floss.

00:33:00Sure, it's important for your dental health

00:33:02and it's easy to assume what you do with it.

00:33:04But dental floss is great

00:33:06in the kitchen as well

00:33:08because it's a very precise cake slicer.

00:33:10Way better than a regular knife.

00:33:14Most kitchen shears

00:33:16have a serrated opening

00:33:18right there at the center

00:33:20where the blades and handles meet.

00:33:22It's something you can use

00:33:24to trim difficult herbs

00:33:26Because of this opening

00:33:28you don't need to pick the leaves off by hand

00:33:30but de-stem them in one motion.

00:33:34The majority of gelatin containers

00:33:36or single-serving yogurts

00:33:38come with a tinfoil lid

00:33:40and in most cases

00:33:42you can use this covering

00:33:44as a disposable spoon.

00:33:46Just peel away the covering

00:33:48and after a couple of simple folds

00:33:50you'll have a perfect little spoon

00:33:52for your midday snack.

00:33:55You might be wearing a dress or a jacket

00:33:57and are about to dig your hand

00:33:59into the pocket when

00:34:01you realize there's no depth to it.

00:34:03The pocket is simply not there.

00:34:05But why would anyone

00:34:07create pockets you can't put anything in?

00:34:09And now would be a good time

00:34:11to pick your iPhone up

00:34:13from off the floor.

00:34:15Well, the reason for fake pockets is simple.

00:34:17If a clothing item has a specific cut or shape

00:34:19pockets may spoil it.

00:34:21They can alter the item's shape

00:34:23already on the retail rack.

00:34:25The solution?

00:34:27Getting rid of pockets in key areas.

00:34:29Plus, fake pockets are obviously cheaper

00:34:31and they don't get stretched out.

00:34:33Interestingly,

00:34:35this practice goes back to the 17th century.

00:34:37That's when pockets were actually removable.

00:34:39They resembled small bags

00:34:41and women, for example,

00:34:43could move them from one outfit to another.

00:34:45Unfortunately,

00:34:47it was also very convenient for pickpockets.

00:34:49They could grab such a pocket

00:34:51and run off with it.

00:34:53Then clothes became more streamlined

00:34:55and slim pockets started to be

00:34:57sewn right into them

00:34:59instead of attachable bags.

00:35:01This was believed to make the shape

00:35:03of a person's silhouette more alluring.

00:35:05But soon, slimmer skirts

00:35:07came into fashion

00:35:09and pockets went out of it.

00:35:11And people started using handbags instead.

00:35:13These days, most pockets are real.

00:35:15But some of them are still fake.

00:35:17So how can we make sure

00:35:19that we don't actually turn

00:35:21a fake pocket into a hole

00:35:23if it's a real one?

00:35:25Well, first of all,

00:35:27take a look at the stitching

00:35:29along the edge of the pocket

00:35:31where it's supposed to open up.

00:35:33If you see a single loose thread,

00:35:35just snip a piece of it

00:35:37and start pulling gently.

00:35:39If the pocket is real,

00:35:41the thread will easily come out.

00:35:43But if you feel that the stitching won't budge,

00:35:45most likely,

00:35:47you have a faux pocket on your hands.

00:35:49If this is the case,

00:35:51just leave it be.

00:35:53And now, let's talk about

00:35:55the other things that make

00:35:57your chips taste like cheese.

00:35:59For example,

00:36:01those lines on some kinds of chips.

00:36:03For one thing,

00:36:05they help with the distribution

00:36:07of spices and seasonings.

00:36:09In other words,

00:36:11all those substances that make

00:36:13your chips taste like cheese

00:36:15are mostly stored inside the lines.

00:36:17Plus, the lines make chips crunchier.

00:36:19Highlighters are filled with

00:36:21so that they don't prevent you

00:36:23from seeing the text

00:36:25after black-and-white photocopying.

00:36:27Photocopiers perceive yellow

00:36:29and light green marks

00:36:31as almost non-existent

00:36:33and don't print them.

00:36:35Now, back in the day,

00:36:37the first jeans had one problem.

00:36:39Workers and miners

00:36:41who were the original jeans wearers

00:36:43put too much pressure

00:36:45on the poor piece of clothing.

00:36:47As a result,

00:36:49Most metallic zippers

00:36:51have a hidden lock inside them.

00:36:53That's why you shouldn't leave

00:36:55the zipper handle in an upward position.

00:36:57When you pull it downwards,

00:36:59it automatically locks.

00:37:01It's all thanks to several tiny grooves

00:37:03hidden underneath the handle.

00:37:05Now, about those horizontal lines

00:37:07on plastic bottles.

00:37:09They help hold bottles up.

00:37:11Some bottles are produced from soft plastic.

00:37:13Without the lines,

00:37:15they wouldn't keep their shape.

00:37:17They twist easily or even break.

00:37:19Bath foam isn't only

00:37:21for fun or a nice smell.

00:37:23It helps regulate the temperature, too.

00:37:25The bubbles keep the water hot

00:37:27and you can enjoy your bath a bit longer

00:37:29with or without your rubber ducky.

00:37:31Ever noticed

00:37:33that layer of clear liquid

00:37:35in gel pens?

00:37:37It's called the ink follower

00:37:39or stopper fluid.

00:37:41The gel in such pens contains

00:37:43pigment particles dissolved

00:37:45in a polymer solution.

00:37:47These particles suspend it

00:37:49but also thin enough to flow first

00:37:51onto the ball and then the paper.

00:37:53The main task of the stopper fluid

00:37:55is to be a barrier to prevent

00:37:57the gel from evaporating

00:37:59or leaking out.

00:38:01Without this transparent fluid,

00:38:03your gel pen wouldn't function.

00:38:05The fluid always stays in one position

00:38:07and doesn't get dissolved with the gel.

00:38:09Neither does it move backward

00:38:11or flow out of the pen.

00:38:13The holes in the bottoms of your earphones

00:38:15allow air to circulate

00:38:17through your ears.

00:38:19It allows to increase low frequencies

00:38:21making the bass sound deeper.

00:38:23The quality of the sound

00:38:25also becomes much better.

00:38:27Some plastic milk containers

00:38:29have dents on their sides.

00:38:31Try as they might,

00:38:33they just cannot park

00:38:35without some damage.

00:38:37Nah, I made that up.

00:38:39These dents serve several purposes.

00:38:41For one thing,

00:38:43when milk spoils,

00:38:45that's when the dent comes in handy.

00:38:47It pops out

00:38:49and doesn't let the jug blow up.

00:38:51Plus, if you ever decide to freeze the milk,

00:38:53it will expand like any other liquid.

00:38:55And then again,

00:38:57the indentation will pop out

00:38:59and prevent the container

00:39:01from breaking inside your freezer.

00:39:03That's a good thing.

00:39:05Airplane windows have rounded edges,

00:39:07and that's a crucial safety measure.

00:39:09It prevents aircraft accidents.

00:39:11Weak spots are usually situated

00:39:13in the corners.

00:39:15In a rectangular,

00:39:17each of them would have

00:39:194 potential weak spots.

00:39:21Under pressure,

00:39:23they would collapse.

00:39:25If you look closely

00:39:27at a trim's overhead lines,

00:39:29you'll see that its contact wires

00:39:31zigzag back and forth

00:39:33instead of going in a straight line.

00:39:35The thing is that all trims

00:39:37have pantographs attached to their roofs.

00:39:39The upper part of the pantograph

00:39:41is gradually worn down

00:39:43by the overhead wire

00:39:45not strictly along the trim's path,

00:39:47but in zigzag patterns.

00:39:49As the trim moves,

00:39:51the pantograph slides along the wire

00:39:53and it wears down evenly.

00:39:55You might've wondered

00:39:57why some gas cans have

00:39:59two holes with caps,

00:40:01one bigger and one smaller.

00:40:03Before, I thought that the little hole

00:40:05was used when you poured something

00:40:07into a smaller container.

00:40:09But I was wrong.

00:40:11A very infrequent occasion.

00:40:13In reality,

00:40:15it's to prevent it from glugging

00:40:17and spilling on your clothes

00:40:19and on the ground.

00:40:21Most of the buttonholes

00:40:23on a shirt are vertical,

00:40:25but the top and sometimes

00:40:27bottom ones are horizontal.

00:40:29The reason is simple.

00:40:31These two buttons slip out

00:40:33more often than others.

00:40:35Luckily, producers have found

00:40:37the solution that can prevent

00:40:39these buttons from slipping out –

00:40:41horizontal buttonholes.

00:40:43These sachets of sugar or salt

00:40:45are easier to open than many people think.

00:40:47There's no need to tear off

00:40:49one of the ends.

00:40:51The right way is actually

00:40:53to tear them down the middle.

00:40:55Some boots have loops

00:40:57sticking out on the back.

00:40:59Their main purpose is to help

00:41:01you pull your shoes on easier.

00:41:03Just tug on the loop while

00:41:05you're pushing your heel

00:41:07into the boot.

00:41:09You can also use these loops

00:41:11to hang your boots on a hook

00:41:13and tie them around your ankle.

00:41:15When you're on board the plane,

00:41:17you might spot a little triangle

00:41:19over your seat.

00:41:21Such triangles show the flight crew

00:41:23the best spots to check

00:41:25the plane's flaps through the window,

00:41:27just in case they're flapping.

00:41:29If your shoes are really slippery,

00:41:31just take a bit of sandpaper

00:41:33and rub it on the soles

00:41:35for better traction.

00:41:37They'll become more grippy

00:41:39and you'll be able to wear them

00:41:41out in the rain.

00:41:43If you drill several holes

00:41:45at the bottom of your garbage can,

00:41:47putting in and taking out

00:41:49trash bags will become much easier.

00:41:51You won't have any problems

00:41:53with suction.

00:41:55You can usually find some silica gel

00:41:57in bags, shoes,

00:41:59and many other things you buy.

00:42:01This shell absorbs excess moisture.

00:42:03Don't throw it away.

00:42:05Each time your shoes get wet,

00:42:07put a few packets of silica gel inside.

00:42:09The thermos wasn't actually

00:42:11invented to keep your coffee warm.

00:42:13It was made by a Scottish scientist

00:42:15who just wanted a safe place

00:42:17to put his chemicals at a stable temperature.

00:42:19So he took two bottles,

00:42:21put the smaller one inside the bigger one,

00:42:23and vacuumed out the air between them.

00:42:25Well, anyway,

00:42:27thanks for the hot coffee!

00:42:29If you look at it on the street,

00:42:31you'll think a fire hydrant

00:42:33is about 3 feet in height.

00:42:35But the actual size of the device

00:42:37used to provide water supply

00:42:39to firefighters all over the world

00:42:41is twice as large.

00:42:43So why is a hydrant underground?

00:42:45They're mostly red,

00:42:47and it's not just a matter of urban design.

00:42:49First of all,

00:42:51they need to be of bright,

00:42:53easily noticeable colors

00:42:55so firefighters can spot them fast

00:42:57when they need to.

00:42:59The choice of color depends

00:43:01on how much water the hydrant can hold.

00:43:03It can sometimes vary depending on the location,

00:43:05but here's the breakdown.

00:43:07A red fire hydrant can splash

00:43:09500 gallons of water per minute,

00:43:11while a green one can process

00:43:131,500 gallons of water per minute.

00:43:15And the most plentiful ones,

00:43:17colored blue,

00:43:19can generally contain

00:43:21over 1,500 gallons.

00:43:23Hey, bowling fans,

00:43:25isn't it super annoying

00:43:27when your bowling ball gets cracked?

00:43:29Turns out that most of them get damaged

00:43:31because of incorrect storage

00:43:33or spikes in temperature.

00:43:35Now come on and face it,

00:43:37since it's already cracked a bit,

00:43:38they mostly make the inner core of the ball

00:43:40of powdered metal oxides

00:43:42like calcium or iron oxide.

00:43:44Then mix them with some resin and catalyst

00:43:46to harden the whole mixture.

00:43:48So that light bulb shape you now see

00:43:50inside of the ball is actually

00:43:52its heaviest part.

00:43:54It also influences how your bowling ball rotates

00:43:56when going down the lane.

00:43:58The same goes with spray paint cans.

00:44:00When you shake it,

00:44:02it makes a weird noise,

00:44:04but what is that thing in there?

00:44:06It's meant to hold the paint mixture in place

00:44:08and maintain its shape.

00:44:10They generally make it out of plastic, metal,

00:44:12or ceramic.

00:44:14It basically acts as a whisk

00:44:16to make sure your paint is well mixed together

00:44:18before you apply it to your surface of choice.

00:44:20Ever wondered how soda bottles

00:44:22keep that refreshing fizz for that long?

00:44:24Well, they have a little plastic ring

00:44:26fastened to the lid.

00:44:28They place it there to keep the gas from escaping

00:44:30and making the soda go flat,

00:44:32even if you shake it around

00:44:34in your bag the whole day.

00:44:36Speaking of things we use on a hot summer's day,

00:44:38wait, wait.

00:44:40Don't put your baseball cap on just yet.

00:44:42Take a look at it for a minute

00:44:44and you'll notice there's a small button

00:44:46on the very top.

00:44:48Is it functional or is it just there

00:44:50for the sake of design?

00:44:52Way back when people started using fabrics

00:44:54to cover their heads,

00:44:56some say the button was actually functional.

00:44:58Since it's on top of the cap

00:45:00where the fabric panels come together,

00:45:02the top button helps keep the cap crown

00:45:04in one single piece.

00:45:06This is more of an aesthetic feature.

00:45:08It's used to cover up the joint point

00:45:10of the fabric panels.

00:45:12Your cap might not have a button at all,

00:45:14but don't you think a cap

00:45:16actually looks better with one?

00:45:18Cotton pads have two sides,

00:45:20and if you take the time to look at them carefully,

00:45:22they're actually different in texture.

00:45:24Just in case you've ever wondered why,

00:45:26the textured side is for applying makeup

00:45:28and the even side is for removing it.

00:45:30Bookworms.

00:45:32This one is for you.

00:45:34Dust jackets that come with a lot of hardcover books

00:45:36to make your book look pretty.

00:45:38They also double as a bookmark.

00:45:40Just fold the pages you've already read

00:45:42underneath the inside of the jacket

00:45:44and voila!

00:45:46Next time you reach out for your favorite shirt,

00:45:48take a look at the top buttonhole.

00:45:50It should be stitched horizontally

00:45:52and all the other ones are vertical.

00:45:54Turns out that the dress shirt was designed this way

00:45:56since the first and the last buttons

00:45:58were the first ones to unbutton

00:46:00throughout the day.

00:46:02They then changed the direction of the buttonhole

00:46:04to ensure the shirt would stay nice and fitted

00:46:06and take it off.

00:46:08These days we have so many variations

00:46:10of this awesome dessert

00:46:12that it's hard to imagine we've ever lived without it.

00:46:14You can find different types of cookie dough ice cream

00:46:16or even chocolate chip cookie cake

00:46:18basically everywhere.

00:46:20But the famous cookie wasn't actually invented

00:46:22until 1930.

00:46:24The story goes that a woman named Ruth Graves Wakefield

00:46:26was preparing some chocolate cookies

00:46:28as she was waiting for some guests to arrive.

00:46:30She soon figured out

00:46:32she was out of baker's chocolate,

00:46:34a crucial ingredient for the classic cookies.

00:46:36To fix things up,

00:46:38she chopped up a block of semi-sweet chocolate

00:46:40thinking it would eventually spread out evenly

00:46:42throughout the batter

00:46:44given the heat of the oven.

00:46:46Things didn't necessarily go as planned

00:46:48but hey, it's great they didn't

00:46:50because this is how she invented this modern dessert

00:46:52we now can't get enough of.

00:46:54And speaking of popular snacks,

00:46:56the potato chip is even younger

00:46:58than the chocolate chip cookie.

00:47:00Well, at least historically.

00:47:02There are many stories trying to explain

00:47:04how it was invented.

00:47:06One of them goes like this.

00:47:08A chef named George Crumb

00:47:10based in New York

00:47:12put the chips together in 1953.

00:47:14He decided to try a different cooking solution

00:47:16when one of his customers

00:47:18didn't have nice things to say

00:47:20about his French fries.

00:47:22He said they were too thick

00:47:24and kind of mushy.

00:47:26Then Crumb came up with potatoes

00:47:28that were thinly sliced

00:47:30and fried until brown.

00:47:33And the result was a bunch of chips

00:47:35with open arms.

00:47:37Ice cream anyone?

00:47:39If the story is true,

00:47:41back in 1904 at the St. Louis World's Fair

00:47:43one ice cream shop owner

00:47:45ran out of cups to serve his dish.

00:47:47So he fashioned a waffle

00:47:49into the shape of a cone

00:47:51and the rest was history.

00:47:53Okay, I'll admit it,

00:47:55chewing gum-like treats

00:47:57have been around since the ancient Greeks.

00:47:59So this one isn't particularly

00:48:02An American inventor

00:48:04named Thomas Adams

00:48:06wanted to mix together different chemicals

00:48:08to create rubber.

00:48:10He tried and failed, for that matter,

00:48:12to play with chicle for his experiment

00:48:14but ended up fashioning this neat treat.

00:48:16They still use chicle to this day

00:48:18to produce most chewing gums.

00:48:20Back in the 1800s

00:48:22there lived a man named Jean-Baptiste Jolly

00:48:24who worked in the fabric industry

00:48:26as a textile maker.

00:48:28How he came up with this next invention

00:48:29has less to do with him

00:48:31and more to do with his maid.

00:48:33The story goes

00:48:35that the woman accidentally

00:48:37knocked a kerosene lamp over

00:48:39onto a tablecloth.

00:48:41Instead of getting upset

00:48:43over the damaged fabric

00:48:45Jolly noticed that the substance

00:48:47actually made the material cleaner.

00:48:49Figured it out yet?

00:48:51Yep, that's how the idea

00:48:53for the very first dry cleaner popped up.

00:48:55A very neat accident,

00:48:57if I do say so myself.

00:48:59Or at least that's how

00:49:01their inventor, a chemist

00:49:03named John Walker

00:49:05called them back in 1826.

00:49:07He scraped a stick

00:49:09coated in chemicals

00:49:11across his hearth

00:49:13totally by accident one day

00:49:15and realized that they ignited

00:49:17and created a spark.

00:49:19Initially made out of cardboard

00:49:21they were then made

00:49:23using wooden splints

00:49:25and sandpaper.

00:49:27Back in the 1940s

00:49:29the scientific community

00:49:31at the time didn't look much into it

00:49:33as the formula didn't seem

00:49:35to have many applications back then.

00:49:37It wasn't until 1951

00:49:39that he looked a bit more

00:49:41into the formula

00:49:43and decided to repurpose it

00:49:45along with a fellow

00:49:47Eastman Kodak researcher

00:49:49named Fred Joyner.

00:49:51They gave it a proper full name

00:49:53but you must know it

00:49:55by the shorter version

00:49:57Super Glue.

00:49:59Back in 1903

00:50:01a scientist named

00:50:03Edward Benedictus

00:50:05knocked over a flask by accident.

00:50:07He looked down

00:50:09and was amazed to see

00:50:11that the glassware

00:50:13had just slightly cracked

00:50:15but maintained its shape.

00:50:17He was expecting it to break

00:50:19into a million tiny pieces.

00:50:21Curious about this hidden feature

00:50:23he looked into it

00:50:25and figured out

00:50:28Crackers have holes in them

00:50:30to stop them cracking

00:50:32and breaking during baking.

00:50:34If the holes weren't there

00:50:36steam would build up inside the cracker

00:50:38and make it collapse.

00:50:40Take a look at a soda bottle

00:50:42and you'll notice a disc inside the bottle cap.

00:50:44This helps seal in the liquid

00:50:46and the drink's fizz

00:50:48stopping it from going flat.

00:50:50The long neck on your soda bottle

00:50:52is designed like that

00:50:54to encourage you to hold it there.

00:50:56The hand will only warm

00:50:58that top bit of the bottle

00:51:00instead of heating up your whole drink.

00:51:02It's always hard to see

00:51:04your food in the microwave

00:51:06because of that pesky black grate

00:51:08on the window

00:51:10but it's there to stop

00:51:12harmful microwaves from escaping.

00:51:14Called the Faraday Shield

00:51:16it protects you

00:51:18as well as ensures

00:51:20that your food cooks properly.

00:51:22Food items like chips

00:51:24can sell you half a bag of air

00:51:26but it's exactly the opposite.

00:51:28Oxygen, the gas we breathe

00:51:30would react with the chips inside the bag

00:51:32and make them go rancid quickly.

00:51:34It's called oxidizing for a reason.

00:51:36Nitrogen, on the other hand

00:51:38is an inert gas

00:51:40that helps keep the foodstuffs fresh

00:51:42and also protects them

00:51:44from breaking during transportation.

00:51:46A bag of chips

00:51:48that has this gas cushion

00:51:50lets you enjoy your crunchies

00:51:52without them turning to potato crumbs.

00:51:54It's important that the inside

00:51:56and outside cook evenly.

00:51:58Before the holes were added

00:52:00the inside would often be greasy

00:52:02and doughy while the outside was crisp.

00:52:04Margins on paper

00:52:06aren't for writing in dates

00:52:08and numbering lists.

00:52:10They were originally added

00:52:12to serve a protective function.

00:52:14Back in the day

00:52:16rats used to be a pesky problem

00:52:18in people's homes

00:52:20and paper was one of their favorite snacks.

00:52:22Margins were added

00:52:24to make it easier

00:52:26rather than taking a bite

00:52:28out of your important work.

00:52:30That hole in your hollow lollipop stick

00:52:32isn't to prevent choking

00:52:34should it ever be swallowed.

00:52:36It's actually there

00:52:38to keep the candy in place.

00:52:40Excess candy flows into the hollow tube

00:52:42and the hole,

00:52:44which when it hardens,

00:52:46keeps the pop in place.

00:52:48If it was a smooth stick

00:52:50the candy would slide off easily.

00:52:52Do you know what that one

00:52:54with long bristles is for?

00:52:56It's for dusting

00:52:58and is perfect for cleaning

00:53:00framed art, blinds and lampshades.

00:53:02What's the difference

00:53:04between a wooden hanger

00:53:06and a plastic one?

00:53:08Aside from helping keep

00:53:10your clothes in shape

00:53:12cedar wood hangers

00:53:14also repel moths and bugs.

00:53:16Salt isn't just used for cooking.

00:53:18It can get rid of tough smells.

00:53:20It also works on shoes.

00:53:22Toasters have a secret slide

00:53:24in the bottom that can be removed

00:53:26so you can clean out

00:53:28all those annoying breadcrumbs.

00:53:30If you ever had problems

00:53:32with popping chocolates from the box

00:53:34look at those little holes around them.

00:53:36They're there to help you.

00:53:38If you push a hole right next to the candy

00:53:40it'll jump out easily.

00:53:42When you take a sip from a coffee cup

00:53:44with a lid

00:53:46it decreases air pressure inside the cup

00:53:48and air tries to get in.

00:53:50The tiny hole on the lid

00:53:52allows air to enter that way

00:53:54so liquid can smoothly

00:53:56pour out the main hole.

00:53:58More on beverage lids.

00:54:00The small button on them

00:54:02let restaurant workers

00:54:04and customers too

00:54:06understand what's in a cup.

00:54:08Near each button there's a name.

00:54:10Just look at which one is pushed down.

00:54:12The numbers on the fruit stickers

00:54:14tell you how exactly they were grown.

00:54:16If there are four digits

00:54:18and the first is four or three

00:54:20the fruit has been sprayed with pesticides.

00:54:22If there are five digits

00:54:24and the first is nine

00:54:26the fruit has been grown organically.

00:54:28If there are five digits

00:54:30and the first is eight

00:54:32the fruit has been genetically modified.

00:54:34When you're on your way back to the car

00:54:37after bagging up everything you bought

00:54:39use loops on a shopping cart

00:54:41to hang the bags.

00:54:43Now softer items like bread, eggs,

00:54:45fruit and veggies

00:54:47won't get squashed by the heavier goods.

00:54:50If you don't have anyone

00:54:52to hold the other end of your tape measure

00:54:54when you try to measure something

00:54:56tap a nail on it.

00:54:58Now simply hook your tape on it

00:55:00using the tiny hole all tape measures have.

00:55:03The square shaped spoon

00:55:05that goes with a McFlurry

00:55:07helps to mix the ice cream toppings

00:55:09through the dessert.

00:55:11The spoon hooks directly to a machine

00:55:13and spins around.

00:55:15Padlocks that are used outside

00:55:17quickly get out of order because of rain.

00:55:19See this little hole in the bottom?

00:55:21It's made for pouring engine oil inside.

00:55:24Do this and the key will again

00:55:26turn in the lock without any difficulty.

00:55:29You keep banging the bottom

00:55:31of a glass ketchup jar

00:55:33but nothing's coming out.

00:55:35Here's a little tip.

00:55:37Turn your ketchup bottle at an angle

00:55:39and tap on the middle of the neck.

00:55:41In many fast food restaurants

00:55:43customers fill tiny folded paper cups

00:55:46to get a portion of ketchup or mustard.

00:55:49Here's the news.

00:55:51The cups are supposed to unfold

00:55:53and turn into small paper platters

00:55:55to hold a great deal more sauce.

00:55:57That little hole on the handle of a pot

00:55:59or a frying pan

00:56:01isn't just for hanging them on the wall.

00:56:03During cooking

00:56:05put the end of your utensil in the hole

00:56:07and it'll be propped over the pot

00:56:09to save your kitchen from extra mess.

00:56:11The blue or any other dark color bristles

00:56:14on your toothbrush

00:56:16will remind you when it's time to get a new one.

00:56:18If you see that bristles have become pale

00:56:21change the toothbrush or its head.

00:56:23An extra hole at the upper part of the sink

00:56:26has multiple hidden functions.

00:56:28First, in case someone forgets to close the tap

00:56:32the water won't overflow

00:56:34and the bathroom won't get flooded.

00:56:36Second, thanks to that hole

00:56:38the water drains faster

00:56:40as it gives an escape for the air

00:56:42helping the water flow down.

00:56:44Most metallic zippers

00:56:46have a hidden lock inside them

00:56:48to save you from awkward situations

00:56:50such as an undone fly.

00:56:52Don't leave the zipper handle

00:56:54in an upward position.

00:56:56When you pull it downwards

00:56:58it automatically locks.

00:57:00It's all thanks to those tiny grooves

00:57:02hidden underneath the handle.

00:57:04Spoiled milk emits gases

00:57:06like most foods when they go off.

00:57:08A classic plastic milk jug

00:57:10has a concave shape on one side

00:57:11so when the gases expand inside the jug

00:57:14it expands too

00:57:16and the concave shape curves out.

00:57:18Also, if you want to save some milk

00:57:20for later and freeze it

00:57:22the jug will expand when the milk gets solid as well

00:57:25occupying more space in a jug.

00:57:27Bath foam isn't only for fun

00:57:30or a nice smell.

00:57:32It also helps regulate the temperature.

00:57:34The bubbles keep the water hot

00:57:36so you can enjoy a bath a bit longer.

00:57:38Anyway, it works for acrylic bathtubs only

00:57:41but those made of metal

00:57:43lose heat really fast either way.

00:57:45Many cups and mugs

00:57:47have little grooves on the bottom on purpose.

00:57:50They're designed for washing machines.

00:57:52The grooves let the water flow

00:57:54and not spill over your feet

00:57:56when you take the cup out.

00:57:58Also, those grooves let the air flow

00:58:00so the cup doesn't crack

00:58:02even if the tea is scalding.

00:58:04A point on an ointment cap

00:58:06is there for a reason too.

00:58:08Most tubes are usually sealed with foil

00:58:11so it's better to avoid opening it with fingers

00:58:13unless you're ready to say goodbye to your nails.

00:58:16A point easily opens

00:58:18even the most safely sealed tube.

00:58:21Escalator brushes aren't for keeping

00:58:23your shoes clean and polished.

00:58:25It might be tough to apply wax

00:58:27right on that brush while the escalator's on the move.

00:58:29It's for your safety.

00:58:31Brushes won't let you come close to the edge

00:58:33so a long coat or bootcut jeans

00:58:35won't end up in between the steps.

00:58:39All Tic Tac containers are designed

00:58:41to dispense one Tic Tac

00:58:43every time you open it.

00:58:45The lid has the same shape as the candy.

00:58:47Turn the container upside down,

00:58:49gently shake it and slowly open it.

00:58:52You'll notice only one candy

00:58:54stuck between those lid grooves.

00:58:56So if you just open the container

00:58:58and shake it until five

00:59:00or even more candies fall into your mouth

00:59:02it means you've been eating Tic Tacs

00:59:04wrong all this time.

00:59:06The pom-pom on top of your beanie

00:59:08wasn't put there as a fashion accessory.

00:59:11The pom-pom was originally added to the hat

00:59:14to prevent sailors from banging their heads

00:59:16on the ceilings of the ships that were too low.

00:59:19The cylinder on the end of a cable

00:59:21is sitting there, useless as it might seem.

00:59:24In fact, this is a ferrite bead

00:59:27that assists with many electrical wires

00:59:30to reduce electromagnetic interference.

00:59:33Electrical wires act like unintentional antennas

00:59:36broadcasting the EMI.

00:59:40There's a reason why the spinning wheel

00:59:42inside the microwave is circular.

00:59:44A circular object will evenly distribute the heat

00:59:47as opposed to a rectangular and square one.

00:59:50When you place containers of these shapes inside

00:59:53the energy is focused on the corners

00:59:55rather than spread evenly

00:59:57like in a round container.

01:00:00The temperature gauge on a toaster

01:00:02is commonly used to determine

01:00:04how crisp you like your toast.

01:00:06But the other, more specific use for the gauge

01:00:09was for the different types of bread.

01:00:11White and sweet types of bread

01:00:13heat up much faster

01:00:15as opposed to heavier brown and rye ones.

01:00:18The older bread is,

01:00:20the more time it will need in the toaster

01:00:22to ensure the golden brown results

01:00:24you're looking for.

01:00:26Most ovens give you the option

01:00:28of leaving the door ajar

01:00:30when broiling a dish inside.

01:00:32You probably think the goal here

01:00:34is to help cool down the oven after use.

01:00:36In reality,

01:00:38its purpose is to focus on cooking

01:00:40the top of the dish

01:00:42and to ensure a crusty layer.

01:00:44Controlling the build-up of heat and steam

01:00:46by releasing it through the slightly ajar door

01:00:49gives you the desired result

01:00:51without cooking the entire dish

01:00:53to a crispy end.

01:00:55You probably noticed that your dishwasher

01:00:57has specific areas

01:01:00for different types of cutleries and dishware.

01:01:02But all the dishware pieces

01:01:04should be facing towards the center

01:01:06and not all in one direction.

01:01:08What types of foods were on the plates

01:01:10will also determine

01:01:12where they should be located in the racks.

01:01:14As the middle of the machine

01:01:16gets the strongest spray,

01:01:18carb-based stains from tomatoes and potatoes

01:01:20should be placed there.

01:01:22The detergent is more focused

01:01:24on the outside during the clean,

01:01:26creating a waterfall-like cleanse.

01:01:28That's why protein-based stains,

01:01:30like from eggs, for example,

01:01:32should be stacked there.

01:01:36Ceiling fans push cool air down

01:01:38on a hot day, circulating the room.

01:01:40But they can serve you

01:01:42during the winter just as effectively

01:01:44if you flick that switch on the side

01:01:46or use the pulley.

01:01:48So if you want to save some money on heating

01:01:50and try to quickly warm up your room

01:01:52on a cold day,

01:01:54turn the fan on.

01:01:57Spread the warm air around,

01:01:59more effectively warming the room up.

01:02:02Do you still use sticky notes

01:02:04instead of those fancy new apps

01:02:06on all possible gadgets?

01:02:08Welcome to the club.

01:02:10Regardless of what you use them for,

01:02:12they can annoyingly curl up.

01:02:14If you've had this issue,

01:02:16it's because you've peeled them

01:02:18from the bottom upwards.

01:02:20Doing it this way causes the curling.

01:02:22Peeling them from the side

01:02:24is one of your daily tasks.

01:02:27Did you know that can openers

01:02:30weren't invented until 50 years

01:02:32after preservation cans

01:02:34had been readily available?

01:02:36So how would it be possible

01:02:38to open a can?

01:02:40There are a couple of alternative methods

01:02:42just in case you've misplaced

01:02:44your trusty opener.

01:02:46All you need is a metal spoon.

01:02:48Set the can down on the counter.

01:02:50Hold onto it firmly

01:02:51and vigorously rub the edge

01:02:53of the can's top over a small area.

01:02:55It takes time,

01:02:57but as you continuously rub,

01:02:59a small indentation soon opens a hole.

01:03:01Once the hole is wide enough

01:03:03for the spoon's tip,

01:03:05pry the lid upwards

01:03:07and keep going along the edges

01:03:09until you can finally access

01:03:11the hard-earned meal within.

01:03:13Most toilets rely on water pressure

01:03:15and gravity to function,

01:03:17so a power outage will not affect them.

01:03:19But if yours does need

01:03:21you must be worried about using it

01:03:23when the power is out.

01:03:25The good news is the power

01:03:27is only used to fill the toilet

01:03:29and not to flush it.

01:03:31As the flushing mechanism will still work,

01:03:33open the toilet tank

01:03:35and pour in a couple of gallons

01:03:37and you're free to flush away

01:03:39whatever you need to.

01:03:41Blockages in shower drains

01:03:43occur over a long period of time.

01:03:45It's inevitable.

01:03:47We lose 50 to 100 hairs a day

01:03:49within our shower drains.

01:03:51Hair only forms the foundations

01:03:53of the blockage

01:03:55and this attracts the buildup

01:03:57of various other things.

01:03:59A great life hack is to use

01:04:01your vacuum cleaner

01:04:03and put the nozzle in the hole

01:04:05once removing the plug.

01:04:07Apply a wet cloth around the nozzle

01:04:09ensuring air cannot escape.

01:04:11The vacuum will suck up

01:04:13the blockages a lot easier.

01:04:15This will help avoid

01:04:18To make your candles last longer,

01:04:20trim their wicks multiple times

01:04:22and keep them as far away from water

01:04:24and moist as possible.

01:04:26It will guarantee that your candle's wax

01:04:28stays firm and steady

01:04:30and continues to burn slower

01:04:32for a longer period of time.

01:04:34The empty space between the panes

01:04:36of the oven door is there for a reason.

01:04:38You can stick a brush in there

01:04:40to clean the oven door glass.

01:04:42It's easy to access this space

01:04:44through the bottom of the door,

01:04:46open the lower shelf

01:04:48then push the brush through the hole.

01:04:50While you're parking in a garage,

01:04:52you might find it difficult

01:04:54to determine how close to it

01:04:56you need to be.

01:04:58Not all cars have sensors

01:05:00ensuring you keep the right distance

01:05:02before the bumper makes

01:05:04an indentation on the wall.

01:05:06Applying a rope with a tennis ball

01:05:08from the ceiling at the right distance

01:05:10will help you learn the best distance

01:05:12to park from the wall.

01:05:14Yes, we all know we should have

01:05:17these around the house.

01:05:19But in case you don't,

01:05:21a great alternative is drawing

01:05:23with a grey lead pencil along

01:05:25the edges of the key

01:05:27and then putting it into the lock.

01:05:29Continue doing this until the keyhole

01:05:31has been adequately lubricated

01:05:33and the key functions smoothly.

01:05:35Pliers are prone to damage

01:05:37when you use them to adjust

01:05:39faucets and shower heads

01:05:41and are also difficult to grip.

01:05:42Take the pliers from the end

01:05:44of an old garden hose

01:05:46and attach them to the jaws

01:05:48of the pliers.

01:05:50You'll find a huge improvement

01:05:52with grip and will avoid

01:05:54wear and tear.

01:05:56You can find a good use

01:05:58for discarded rubber

01:06:00for different things

01:06:02around the house.

01:06:04When fed up with tightening

01:06:06or loosening with a screwdriver,

01:06:08try using a simple rubber band.

01:06:10Moving cement blocks

01:06:12isn't safe for your lower back.

01:06:14Even with a wheelbarrow,

01:06:16it can be a risky process

01:06:18to place the cement

01:06:20onto the ground without causing damage.

01:06:22Three simple cylinder pipes

01:06:24can make a world of difference

01:06:26regardless of the size of the block.

01:06:28Try lifting the edge

01:06:30onto the first pipe

01:06:32with a pry bar,

01:06:34then pushing and maneuvering

01:06:36as you gradually direct

01:06:39That first strike on a nail

01:06:41can be a great success

01:06:43or will result in a throbbing thumb.

01:06:45A bobby pin is perfectly shaped

01:06:47to hold a nail in place,

01:06:49allowing for your hand

01:06:51to be clear out of harm's way

01:06:53and for you to strike

01:06:55the nail without fear.

01:06:57Use a crayon instead of a pen

01:06:59or pencil while working

01:07:01with a wet saw

01:07:03to ensure the markings

01:07:05are not removed.

01:07:08Checking the drains on the roof

01:07:10and determining when they need

01:07:12to be cleaned can take a lot of time.

01:07:14Using duct tape,

01:07:16attach a mirror on the end

01:07:18of a long broom

01:07:20and review whether the drains

01:07:22need to be cleaned.

01:07:24To further assist with your balance

01:07:26as you check on the gutters,

01:07:28attach a pair of old trainers

01:07:30to the end of the ladder.

01:07:32The spread of the shoe

01:07:34and its grip will ensure

01:07:37So you can never use it all at once.

01:07:39The hardened tips of liquid caulk

01:07:44grab used cork and drill through

01:07:46to make a perfect lid

01:07:48concealing the liquid caulk.

01:07:50Now it's ready to be

01:07:52used again with no blockages.

01:07:54OK, I know it's kind of cold

01:07:56to the touch,

01:07:58especially on a freezing winter's day.

01:08:00But did you know that brass

01:08:02doorknobs actually serve a purpose

01:08:03Brass has antimicrobial properties.

01:08:06That means it can help get rid of harmful germs and bacteria, sometimes in up to 2 hours.

01:08:12In high-traffic areas, that's all the more useful, but since brass is much costlier than

01:08:16other metals like nickel and steel, you barely see these types of doorknobs anymore nowadays.

01:08:22Speaking of lovely multi-purpose items, most screwdrivers have a tiny little secret of

01:08:26their own.

01:08:27They can sometimes be slid through a wrench so that they can be used to create more torque

01:08:31when twisting.

01:08:33Not to mention the uses when it comes to bolts in hard-to-reach places.

01:08:38There's a reason why buttons on women's shirts are for the left-handed, and it has nothing

01:08:42to do with fashion.

01:08:44This practice dates back to the times when chambermaids were helping ladies dress themselves,

01:08:48and it was easier for them to perform their job with this orientation.

01:08:53Having the buttons placed as such indicated a sign of wealth, so it's easy to imagine

01:08:58why the practice carried on, even though most people dress themselves nowadays.

01:09:03Next time you receive a package in your mail, take a look at your box cutter.

01:09:07If it features some diagonal lines on the blade, you're in for a little design perk.

01:09:11Turns out that these are blades that snap off.

01:09:15Continuously cutting cardboard can dull the sharp edge of the blade.

01:09:18To help prevent the need to buy a brand new box cutter, the top segment along the next

01:09:22line can be broken off to reach a new sharp edge.

01:09:26To do this, check out the small hole at the base of the tool, sometimes called the blade

01:09:30snapper.

01:09:32The people that first came up with this brilliant invention were engineers inspired by the way

01:09:36chocolate bars are segmented.

01:09:39Hold on a minute, don't throw away the cardboard package just yet.

01:09:42Most likely, you'll have some silica gel packets somewhere at the bottom of the box.

01:09:46Since this gel is basically a drying tool, it gathers up the moisture out of its environment,

01:09:51so you can store these packets for further occasions.

01:09:54Whether you'll need to dry out your phone or some other electrical object, you can place

01:09:58them in a container next to the silica gel to reduce the damage.

01:10:03You don't have to be a mechanic to know when a standard car tire needs replacing, since

01:10:07they come equipped with a neat indicator.

01:10:10Take a closer look, and you'll see that treads within the tire are a bunch of rubber notches.

01:10:15When the treads are evened out with the perpendicular bars, it's a sign you need to book an appointment

01:10:20with your local car service.

01:10:22It's most likely the tires have lost most of their traction, and may not be safe for

01:10:26driving any longer.

01:10:28The upper corners of a car windshield feature textured black dots melted into the glass

01:10:33edges.

01:10:34This neat add-on isn't there for design purposes.

01:10:37It's called Frit Glazing, which means that a special type of ceramic paint is added to

01:10:43the window for protecting its sealant from UV rays.

01:10:47It also conceals and creates a coarser surface for the adhesive used to set the window in

01:10:52place.

01:10:54Whenever you're up for a drive, check out if there's a small tab under your car's rearview

01:10:59mirror.

01:11:00Bet you didn't know it's there to help switch the mirror from daytime to nighttime views.

01:11:05It uses a prismatic glass technology to blur the reflection and reduce the glare of headlights

01:11:11behind you in traffic.

01:11:13People came up with these manually tilted mirrors in the 1930s, but they became standard

01:11:17somewhere in the 1970s.

01:11:20While you're in the car, check out the headrests, as you most likely don't know that they carry

01:11:25a little disguised purpose.

01:11:27Of course, they're adjustable to accommodate passengers of any height so that they get

01:11:31the proper support for their heads and necks.

01:11:34The hidden feature is that they are detachable and come with two very solid metal bars.

01:11:40Should you ever find yourself stuck in a car and need to make a fast getaway, these bars

01:11:44come in handy to crack out the car windows.

01:11:48So you're out for a drive and you're suddenly out of gas.

01:11:51What I'm about to describe sounds more like a meme than an actual situation bound to happen.

01:11:56But what if you're in such a hurry that you accidentally drive off with the gas nozzle

01:12:00still in the tank?

01:12:02Well, the nozzles have been designed to prevent any hazards from happening, rest assured.

01:12:07They feature a breakaway device that will allow the hose to separate when taken out

01:12:11with enough force.

01:12:13Initially designed in the early 20th century to be worn exclusively by basketball players,

01:12:19sneakers soon became one of those fashion fundamentals similar to jeans and leather

01:12:23jackets.

01:12:24If you take a closer look at them, you'll see they have two extra holes on the side,

01:12:28similar to the shoelace holes.

01:12:30They're manufactured as such not only to provide extra ventilation but to allow people to get

01:12:35extra creative with their laces when wearing the shoes.

01:12:39Admit it, you've always thought that chopsticks are merged at the end for the sole purpose

01:12:43of keeping them together until you're ready to dig into your meal.

01:12:46That may or may not be the whole truth.

01:12:49Under a more detailed inspection, the wooden tools feature a square-shaped end.

01:12:54Chopsticks manufactured like this date back to an old Japanese traditional design, which

01:12:59can help with breaking the ends easily.

01:13:02The separated end can then be used as a resting block for the chopsticks to keep it more sanitized

01:13:07in hopes it can be used again, since they won't be touching the table or any other

01:13:11surface.

01:13:12Women's bikes have a special design which, surprisingly, has a historical and fashionable

01:13:18purpose.

01:13:19The lower frame is for the most part meant to make up for the generally shorter height

01:13:23of ladies, compared to that of the average gentleman.

01:13:27While that is the case for handlebars and saddles, the overall frame is lower for an

01:13:31additional purpose.

01:13:32Way back when women wore long skirts and dresses all day, every day they needed to make sure

01:13:37their outfits wouldn't get caught in the frame.

01:13:40That's how we came up with a lower-framed bicycle, perfectly made for women and their

01:13:44needs at the time.

01:13:47The fact that toothpastes are multi-colored is not just a nice perk to make dental hygiene

01:13:52more fun.

01:13:53There's a secret meaning related to each of the colors, which dates back to the 1970s.

01:13:58In those days, people grew more and more interested in their oral health care, and

01:14:03as such, they were looking for products which could do more than merely clean their teeth.

01:14:09One company was the pioneer in that regard, adding mouthwash to its toothpaste, meaning

01:14:13the blue strip.

01:14:15They later added on the red strip, meant to feature ingredients which helped with gum

01:14:19care.

01:14:21Speaking of toothpaste, check the cap next time you open a new tube.

01:14:24You may be in for a little surprise.

01:14:27There's a pointed cone shape inside the cap, so you can puncture the seal of the toothpaste

01:14:31without cutting yourself or ruining your manicure.

01:14:34Not to mention, it's more hygienic since you won't be able to transfer germs or other

01:14:38bacteria into the product itself.

01:14:42On the subject of bathroom countertop items, toothbrushes come with a neat add-on hidden

01:14:47in the bristle patterns.

01:14:48Apart from making the toothbrush look cooler, they also do come with a practical purpose.

01:14:54Most toothbrushes come with a pattern of blue bristles intertwined with white ones.

01:14:58The blue dye is meant to fade out, signaling the time when you need to replace your toothbrush.

01:15:04Dentists say that toothbrushes should be replaced every three to four months, but it does serve

01:15:09as a great reminder in case you forget.

01:15:11Still love playing with Lego?

01:15:14Don't judge.

01:15:15Hey, it's a great hobby for all ages.

01:15:16Notice there's a hole on top of the Lego heads?

01:15:19Behold, you're looking at a safety feature that the people at Lego designed to prevent

01:15:24choking hazards.

01:15:26The most dangerous issue should a person swallow any of these pieces is the blocking of the

01:15:30airways.

01:15:32Designing a hole inside the Lego head helps the air to flow freely through the piece until

01:15:37it can be removed safely.

01:15:39We're now used to all sorts of modern light bulbs, some tubular, some shaped like diamonds,

01:15:44and some even twisted all together.

01:15:47Historically, light bulbs were round and the initial shape served a purpose in itself.

01:15:53It was mainly connected to the fact that glass bulbs were hand-blown, which gave them the

01:15:57round shape to begin with.

01:15:59The hidden practical reason was that the light bulb filament needed to be at the same distance

01:16:03from every surface of the glass sphere.

01:16:06The easiest way to achieve this was to make the glass in the shape of a globe.

01:16:12Hey, have you ever been vibing out in your room, listening to some of your favorite songs,

01:16:17admiring the subwoofer of your speaker as it delivers magnificence to your eardrums?

01:16:23We all have!

01:16:24But have you ever asked yourself why that same speaker, along with other speakers across

01:16:28the globe, is almost always black?

01:16:31Some of you are probably screaming at your screen right now about your speaker being

01:16:35green, red, or any other color found in the rainbow.

01:16:39Number one, I said almost always.

01:16:42And number two, if you look closely at the gorgeous design of your brightly colored music

01:16:46player, you'll often find that the speaker beneath it is still colored black.

01:16:52One possible explanation for this is that the original technology of speakers had a

01:16:56diaphragm with black particles on it.

01:16:59So as soon as a sound is amplified, it sends a charge through the diaphragm, and these

01:17:04black particles are driven upwards.

01:17:06The carbon particles bouncing and touching the upper membrane of the diaphragm are responsible

01:17:11for creating some of the distinct sounds from our speakers that we all love so much.

01:17:16Speaker manufacturers must've gotten tired of their products changing color with prolonged

01:17:21use, combined with these black particles settling on the upper membrane of the diaphragm.

01:17:26So their logical solution was to color most speakers black.

01:17:31Another more practical belief as to why speakers are mostly colored black is that it's a hue

01:17:37that easily matches up with many types of decor.

01:17:40Walls, furniture, and clothes all often look quite well when combined with this color,

01:17:46which is why it's so prevalent everywhere you go.

01:17:50Listening to music has repeatedly scored in the top 10 pastimes in the US based on research.

01:17:55Nowadays, you find sound speakers everywhere.

01:17:59Between your television, laptop, and your phone, you can't escape them!

01:18:04But let's take a look at how they started off.

01:18:07Their origins are in radio and telephone technology.

01:18:10The first form of a speaker was developed by Johann Philip Rice in 1861.

01:18:16The German was a self-taught inventor and installed the speaker on his telephone.

01:18:21It was just about able to reproduce clear tones, but it could also replicate muffled

01:18:26speech after a few revisions.

01:18:30Alexander Graham Bell, the inventor of the telephone, decided to try and produce an improved

01:18:35version of Rice's speaker.

01:18:37Essentially, Bell and other inventors wanted to make an electrodynamic speaker.

01:18:42By 1877, it was still yet to exist, but due to the desire of inventors worldwide to change

01:18:49this, research confirmed that it was extremely possible to make one.

01:18:54In particular, the work of Wernher von Siemens, who came up with the idea of an electromagnetic

01:18:59coil-driven speaker, was a driving force in arriving at this conclusion.

01:19:04Why are there magnets in speakers, you might ask?

01:19:08Every speaker nowadays has an electric current, something the inventors we're discussing

01:19:12would never have taken for granted at any point in their lives.

01:19:16When this electric current is changing, it produces a magnetic field.

01:19:21To make the panel of the speaker move, magnets are used to create an opposing magnetic field

01:19:26which creates vibrations.

01:19:28These vibrations are the sound we end up hearing.

01:19:31The bigger the magnet, the louder the speaker will be.

01:19:34Another inventor by the name of Thomas Edison from the U.S. had filed a British patent for

01:19:40a system using compressed air for an amplifying mechanism.

01:19:44The first commercial electric loudspeaker saw the light of day only in 1924.

01:19:50The sound quality produced by this speaker was good enough for motion pictures.

01:19:55It took nearly 20 years for the next groundbreaking development in the world of loudspeakers.

01:20:00This came with the arrival of the duplex driver in 1943.

01:20:05It offered better clarity and coherence at high volumes, which was important in movie

01:20:09theaters.

01:20:10Fittingly, it was nicknamed the Voice of the Theater.

01:20:14The duplex driver was immediately tested by the Academy of Motion Picture Arts and Sciences

01:20:19and instantly made its film house industry standard in 1955.

01:20:24Until now, this loudspeaker design is still used.

01:20:28Indeed, the film industry does seem to put a lot of effort into its sound, and so do

01:20:33the theaters we watch them in.

01:20:35You may have noticed that these buildings often have thick curtains on the walls.

01:20:40These are soundproof or acoustic curtains, and both are much thicker than regular curtains.

01:20:46They will either consist of heavier fabrics that are tightly woven or have better quality

01:20:50linings.

01:20:51This means that these curtains will absorb sound and reduce the acoustic reflection off

01:20:56the ceiling, windows, and flat walls of the room.

01:20:59This ultimately creates a much better sonic experience.

01:21:03The carpet floors are so thick in theaters for the same reason.

01:21:07It helps to trap sound by providing insulation.

01:21:10From a practical standpoint, this carpet is also set up to prevent the sound of footsteps

01:21:14during film screenings.

01:21:17This concept of trapping sound is also the reason why putting a phone inside a cup will

01:21:22make the phone's speaker seem louder.

01:21:24Any speaker sitting or suspended in an open space projects its sound in all directions.

01:21:30As the speaker vibrates to create sound waves, an equal amount of energy leaves from both

01:21:36the front and the back.

01:21:38By placing a speaker in some form of enclosure, we can redirect some of the energy that comes

01:21:43from the back of the speaker and project it forwards.

01:21:47By putting the speaker in a cup, you're directing the sound more efficiently.

01:21:51It travels only one way, making it seem louder than what you'd hear when you take it out

01:21:56of the cup.

01:21:58Speaking of phones and speakers, ever wonder why your mobile device makes your speaker

01:22:02produce a buzzing noise?

01:22:04This can occur when the two gadgets are near one another, and your mobile is trying to

01:22:09send and receive data.

01:22:11The transfer of information produces electromagnetic disturbances in the medium around the speakers.

01:22:17It creates noise in the audio, and as a result, you can hear the buzzing sound coming from

01:22:22the speaker.

01:22:23A simple way to protect the amazing vibe your speaker is creating for you from this irritating

01:22:28buzzing noise is just to move your phone away from your speaker, or vice versa.

01:22:34This will eliminate what is officially known as electromagnetic interference.

01:22:41Research across America shows that, on average, 74% of people own two or more pairs of headphones.

01:22:4846% of them mention they listen to their headphones for more than 2 hours per day.

01:22:53Some choose the headphones by their looks, others by the sound quality.

01:22:57In either case, finding the right pair is important since a lot of people are willing

01:23:02to spend over $100 on it.

01:23:05Headphones have become a true fashion accessory.

01:23:08That's why well-known figures are trying to make an impact in the headphone industry

01:23:12like it's the fashion industry.

01:23:15Music moguls Dr. Dre and Jimmy Iovine came up with the idea for the now world-famous

01:23:20Beats by Dre Headphones brand.

01:23:23They were walking along the Pacific Ocean one day in 2006 discussing a sneaker deal

01:23:28as they had an offer on the table from a major brand in that arena.

01:23:33After some discussions, they decided they wanted to do something they were more passionate

01:23:37about and landed on headphones.

01:23:40The duo's idea turned into a brand that was purchased by Apple in 2014 for $3 billion.

01:23:47It was the largest deal in Apple's history, and Beats by Dre controlled 70% of the headphone

01:23:53market at the time of signing.

01:23:55The move allowed Apple to take over the headphone space.

01:23:58The release of their popular wireless AirPods headphones in 2016 was another reason it happened.

01:24:05But how do these popular wireless headphones that many of us own actually work?

01:24:10These headphones rely on internal batteries to have enough power to remain wireless.

01:24:16Most often, they have conveniently built-in rechargeable batteries, but sometimes they

01:24:20keep going thanks to standard AA or AAA batteries.

01:24:25They receive wirelessly transmitted signals from their paired audio sources, be it your

01:24:30phone or laptop.

01:24:32These signals are encoded by the source device and transmitted most commonly via radio frequencies

01:24:38or infrared carriers.

01:24:40The headphones receive the signal and decode it to audio.

01:24:43And just like that, it's music to your ears.

01:24:49Road and construction workers are usually dressed in orange because the bright orange

01:24:53hue is visible even in bad weather.

01:24:56It's the most effective color to attract attention and alert people.

01:25:00No wonder lots of safety jackets and traffic cones are orange as well.

01:25:04The stop sign has an eight-sided shape to help drivers recognize it easily, even if

01:25:08they see it from the back.

01:25:10And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing

01:25:15the stop sign with any other at night.

01:25:18The rumble strips on the side of the road are placed there to alert drivers who doze

01:25:22off behind the wheel.

01:25:24When their tires move over these strips, the noise and vibration work like an alarm clock.

01:25:29There are magnetic locks on fuel hoses at gas stations.

01:25:33They come in handy if someone drives away with the gas nozzle still attached to their

01:25:36car.

01:25:37In this case, the lock detaches the hose automatically.

01:25:40Oh, that's embarrassing.

01:25:43Gasoline looks like a rainbow in a puddle because it can't mix with water.

01:25:46It forms a thin membrane over it.

01:25:49When light reflects from it, and the water at the same time, you've got a rainbow.

01:25:54A triple handle on a jerry can is there to make it easier for two people to carry it

01:25:59and distribute fuel evenly.

01:26:01Gas cans often have a second hole that actually needs to be uncapped too before you pour the

01:26:06gas.

01:26:07The air passage will prevent it from pouring out, so no more fuel waste.

01:26:12Most gas cans have two holes with caps, a bigger and a smaller one.

01:26:17You're supposed to uncap the smaller hole before pouring gas inside the bigger one.

01:26:21That'll prevent the liquid from glugging and spilling all over your clothes and the ground.

01:26:26Another little thingy we often neglect is a point on an ointment cap.

01:26:31Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails

01:26:35isn't the best idea.

01:26:37A point easily opens even the most safely sealed tube.

01:26:42You can use most screwdrivers together with a wrench to create more torque.

01:26:47Just place the wrench over the handle of the screwdriver.

01:26:50This way, you'll need to apply a lot less force than before.

01:26:53You'll also be able to get to hard-to-reach areas more easily.

01:26:58They install cameras in shops, banks, and hospitals to monitor everything.

01:27:03If something happens, you can call the police or rescuers.

01:27:06The camera really helps to solve a lot of problems.

01:27:09Why are there no cameras on planes?

01:27:12The crew keep order on the plane, but they won't be able to do anything if something

01:27:16serious happens.

01:27:18Besides, there's nowhere to run on the plane.

01:27:21During the flight, the cameras are useless, and after the flight, the words of the passengers

01:27:26work ideally instead of cameras.

01:27:28So, if cameras do no good, then why spend money on them?

01:27:33Water is great at cleaning stuff because it has triangular molecules.

01:27:36They're made of one oxygen and two hydrogen atoms, um, H2O.

01:27:41Such molecules have slightly different charges on their opposite sides, pretty much like

01:27:45magnets.

01:27:47That's why water easily sticks to other molecules, including those that make up dirt.

01:27:52Lots of private houses have triangular-shaped roofs because this allows rain, snow, and

01:27:56fallen leaves to slide off the slope.

01:27:59If all this stuff piled up on top of your house, one day, your roof would collapse.

01:28:05When a storm is coming, clouds seem to turn dark, but it's just an illusion.

01:28:09Thin clouds on a sunny day let the light through easily.

01:28:13They also scatter all the colors of the light spectrum.

01:28:16This makes us perceive the clouds as white, but the thicker the clouds are and the more

01:28:20water droplets they contain, the less light they let through and the darker they look.

01:28:25A good doorknob is the one made of brass, bronze, or some copper alloys.

01:28:31These metals have an anti-germ effect.

01:28:34Bacteria spread way slower on them.

01:28:37They also get rid of germs pretty fast, within a couple of hours.

01:28:41Nope, it doesn't mean you don't have to wash your hands.

01:28:45Diamonds have such symmetrical shape to show you their brilliance.

01:28:48Initially, the gems aren't so beautiful.

01:28:51They go through several stages of cutting and then become pieces of elegance.

01:28:56Most of these stones have a round shape with slightly pointed corners.

01:29:00Diamonds shine the brightest in this shape.

01:29:03Why are there two holes in the socket?

01:29:06The left hole is neutral, the right hole is not, and the gap underneath is ground.

01:29:11Electricity needs to flow through the chain.

01:29:14The current flows from the hot slot, passes through your phone charger, for example, and

01:29:19then goes through the neutral hole.

01:29:21Ever wondered what that small pocket on your jeans is for?

01:29:25People used to wear watches on chains.

01:29:27That small pocket was meant for it.

01:29:29Now, almost no one wears such a watch, but the pocket remains.

01:29:33You can still keep something small in there, like a ring.

01:29:37In London, there are some poles that look like street lamps, but there are no bulbs.

01:29:42Well, their official name is stink pipes, and they're a thing of the past now, but

01:29:46they used to come in handy back in the 19th century.

01:29:50These hollow poles would vent away the air and explosive gases with bad smells to prevent,

01:29:55shall we say, unwanted consequences.

01:29:59Most kitchen shears have metal plier-like teeth in the middle.

01:30:02Between the handle grips, they can help you crack nuts, crab shells, and other tough products.

01:30:07You can also open jars and bottles or remove herb stems with their help.

01:30:13Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and

01:30:17scrapes.

01:30:18They scatter the light that hits the material.

01:30:21When you coat your shoes in a layer of wax, you fill these tiny crevices.

01:30:26The surface becomes smoother, and the rays of light bounce off it more evenly.

01:30:30That's why the leather looks shiny.

01:30:33Photocopiers are filled with a special semi-transparent fluorescent ink that can glow in dim light.

01:30:39Yellow and light green hues are the most popular because they don't prevent you from seeing

01:30:44the text after black-and-white photocopying.

01:30:47Photocopiers perceive yellow and light green marks as very pale and don't print them.

01:30:52They make magnets shaped as a horseshoe because this increases the magnetic force.

01:30:58Colors matter, too.

01:30:59The blue part indicates the south pole.

01:31:01The red part, the north pole.

01:31:03The two poles work simultaneously and increase the attraction force.

01:31:08The dime-sized holes in elevator doors is actually a keyhole.

01:31:13If the doors get stuck, an operator can open them manually thanks to this hole.

01:31:17They'll just insert a special key.

01:31:20The tiny hole in the airplane window is there to balance air pressure.

01:31:25The window has three layers.

01:31:27The outer pane is extremely sturdy.

01:31:29It can withstand air pressure differences during takeoff and landing.

01:31:33The inner pane, which is the closest to you, is made of cheaper materials.

01:31:38It prevents potential damage to the window.

01:31:40The hole itself is in the middle pane.

01:31:43It not only balances the pressure but also prevents the window from fogging.

01:31:48Escalator brushes are there for your safety.

01:31:51They don't allow you to come too close to the edge of the escalator.

01:31:54This way, your clothes won't end up between the steps.

01:31:58You see the sun as yellow or orange.

01:32:01Because the atmosphere of our planet scatters such colors as blue, green, and violet, this

01:32:06is also why the sun looks warmer at sunrise and sunset.

01:32:10Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.

01:32:15You'll rarely see them lying around without one of those.

01:32:17It's pure marketing, and that color isn't a random choice.

01:32:21When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to

01:32:27you.

01:32:28So, you're more likely to buy them, right?

01:32:30Lemons are usually sold in green mesh bags for a similar reason.

01:32:34If you pack them in red, they'll appear more orange.

01:32:37Green goes better with yellow and makes those lemons stand out.

01:32:42Mattress manufacturers make a limited number of different mattresses, and the only way

01:32:46to make them look different is to come up with a fancy stitching pattern.

01:32:50Two mattresses of two different companies might be the exact same quality but cost differently.

01:32:56Most people will never know it and will decide that different patterns mean something in

01:33:00terms of quality.

01:33:01So, when shopping, don't mind the pattern at all.

01:33:05Almost all hotels have white bedsheets.

01:33:08They choose this color specifically to show how high their standards of cleanliness are.

01:33:12The whiter and brighter the sheets are, the more luxurious the hotel seems.

01:33:17It's much easier to see dirt and stains on white linen.

01:33:20It's like proof that you've checked into a clean room.

01:33:24You just spent the entire morning running errands up and down the street, and you finally

01:33:28stopped to treat yourself to a cup of coffee.

01:33:31You enter the nearest coffee shop, place your order, and notice that actually, you really

01:33:36need to use the bathroom.

01:33:38It's a regular-looking public one with multiple stalls.

01:33:41As you pick yours, the one in the middle, you get inside, and your mind starts to wander.

01:33:47Why on Earth do bathroom doors have a half-inch gap between the door and the lock?

01:33:51And why on Earth do they have a huge gap between the door and the floor?

01:33:56Can we have a drumroll for this moment, please?

01:33:59Well my friend, there is not only one specific reason why public bathroom doors have so many

01:34:04gaps in them, but rather several.

01:34:07Public toilets are designed to make people spend as little time there as possible.

01:34:11You aren't supposed to feel comfortable or at home.

01:34:14So the design would have to reflect this notion.

01:34:17Here come the gaps.

01:34:19In some bathrooms, gaps are so big that users may even feel self-conscious about doing their

01:34:25business out of preoccupation that the rest of the people standing in line will see them.

01:34:30Then there's the matter of pricing.

01:34:33Making custom doors can be a heavy burden for the people building public toilets.

01:34:37This would mean understanding exact measurements so that doors would always fit the mold of

01:34:42the stalls it's supposed to be installed into.

01:34:45Not all the gaps in public bathrooms are necessarily the same size.

01:34:50They may vary, even if this variation is small and often unnoticeable.

01:34:54So these gaps actually help to reduce the margins of errors and to turn production more

01:34:59cost-effective for the people financing them.

01:35:03In case a door comes wider or more narrow than it should, the gap regulates the differences

01:35:08and allows for their installation anyway.

01:35:11There is also the case of air circulation.

01:35:13The last thing you want to do in a public bathroom is to trap odors.

01:35:18So you need a little space under and between the doors to allow the air to flow.

01:35:23Finally, the gaps are a big safety measure.

01:35:26It can always allow for people on the outside to see if someone inside a stall isn't feeling

01:35:31too okay and maybe needs some help.

01:35:34And what about that extra hole in the upper part of the sink?

01:35:37It has a name in everything – the overflow hole.

01:35:41And it's designed to keep the sink from flooding.

01:35:43So in case someone forgets and keeps the faucet going for too long, or the sink gets clogged

01:35:48and water can't drain down from the main drain hole, the overflow hole comes in to

01:35:53save the day.

01:35:54Let's say it buys you a little time before you have the entire bathroom floor flooded.

01:36:00Have you ever noticed how satisfying closing the door of a car can be?

01:36:04Car manufacturers devote a great deal of time to designing these sounds.

01:36:08Studies have shown that they create a perceived sense of quality in the buyer.

01:36:13It all begins with the primary material.

01:36:16While older cars used to be made with heavier materials, car doors nowadays are produced

01:36:20with lighter tin, which can make a rather unpleasant metallic sound once you shut them

01:36:25closed.

01:36:26So car companies employ sound engineers to ensure that there is the exact amount of foam,

01:36:32mats, and tin in a car's composition to make the most comforting sound possible.

01:36:37And what about those tiny dots on the top of your car's front window?

01:36:41The pattern of these little black dots minimizes distractions for your eyes.

01:36:46This black part, also known as frit, normally gets warmer than the clear parts, which prevents

01:36:51the windshield from deforming.

01:36:54And no, the tab under your rear-view mirror is not made only for the purpose of hanging

01:36:58fluffy dice or aromatic-pleasing air fresheners.

01:37:02It's actually a switch that allows you to adjust the position of the mirror depending

01:37:06on the time of day.

01:37:07Flip it one way, and it's the daytime driving mode.

01:37:11Flip the other, and you're ready to drive safely during nighttime as it tones down the

01:37:15glare coming from headlights of the cars behind you.

01:37:19Next time you head out to the supermarket, make sure to keep this in mind.

01:37:22In case you don't have a coin to unlock these shopping carts, there is a well-kept secret

01:37:27that can help you out.

01:37:29If you have your house keys on you, check for a rounded keyhead.

01:37:33If you happen to find one, try using it to unlock the cart.

01:37:36It should fit perfectly in there, replacing the need to carry coins around.

01:37:41Because if we're being honest, who still has them?

01:37:44Elevators.

01:37:45If you want to ride them on your terms, and your terms only, make sure to try something

01:37:49out.

01:37:50Most elevators have a secret button combination you can use to skip all the other selected

01:37:54floors and go directly to the one of your choosing.

01:37:58This might work out, especially on those days when you've pressed 13, but you wanted to

01:38:03press 33.

01:38:04On most elevators, this works once you simultaneously press the close door button together with

01:38:09your floor number.

01:38:11This should help you get to your floor without stopping.

01:38:14Some elevators require you to double-press the selected floor numbers, as double-pressing

01:38:19will often cancel the previously made request, while other elevators require you to hold

01:38:24the open door button and then double-press the buttons of the floors you'd like to

01:38:28cancel.

01:38:29Now, to stay out of trouble, it's best not to cancel the floors of the other people in

01:38:34the elevator.

01:38:35They won't take it kindly.

01:38:37Also keep in mind that there are elevators that might not have this function.

01:38:41For honey-lovers out there, go ahead and raise your hand.

01:38:44If your pot of golden honey is crystallized, know that it is actually a good sign.

01:38:50Crystallized honey means that it hasn't been pasteurized, which means better product quality.

01:38:55With a decrease in temperature, the natural ingredient of honey, also known as glucose,

01:39:01will make it crystallize.

01:39:02Now, try making the best of it.

01:39:04To add some texture to your oatmeal or toast, add a layer of crystallized honey and enjoy

01:39:09nature's sugar.

01:39:11And if you don't like crystallized honey, plop it in the microwave for a minute or two.

01:39:15Ah, winter and fall.

01:39:17You know what this means, right?

01:39:19Sweater weather.

01:39:20But there's nothing more annoying than wearing your beautiful wool sweater and itching yourself

01:39:25all the way through it.

01:39:27Actually, I can be more annoying than that, but let's talk about itchy sweaters.

01:39:31To keep this from happening again, here's the secret.

01:39:34Turn your sweater inside out and soak it in cold water.

01:39:38Add 2 or 3 tablespoons of vinegar and let it sit for a while.

01:39:42Then drain the water.

01:39:44Now while the sweater is still wet, massage a generous amount of hair conditioner into

01:39:48the fibers of the wool.

01:39:51After letting it soak in the hair conditioner for about 30 minutes, gently press the excess

01:39:55water out of the wool and leave it to dry flat on a towel.

01:39:59There you go, no more itchy sweater!

01:40:02Any fast-food restaurant you go to will hand out small paper cups for customers to fill

01:40:07with their ketchup, mustard, or barbecue sauce.

01:40:10But if you're eating some chicken nuggets or trying to dip your burger into the cup,

01:40:15there's always that bit of sauce that seems impossible to reach.

01:40:19Next time, try unfolding the cup.

01:40:22It'll turn into a small paper plate, and this way you'll get all the ketchup you poured

01:40:26in the first place.

01:40:29Padlocks used in outdoor environments should be cleaned and lubricated every 3 months.

01:40:34Regular lubrication will help prevent padlocks from freezing in cold weather conditions.

01:40:39Look for the tiny hole on the bottom of the lock, then pour oil into it, and there you

01:40:44go, it opens again!

01:40:47One thing we often neglect is a point in an ointment cap.

01:40:50These pointy surfaces were designed to help us break the tinfoil protection of the ointment

01:40:55tube.

01:40:56You just turn the cap over and break the ointment seal with its own cap, and there you go!

01:41:03After a long day of work, all you really need to do is a bubble bath.

01:41:07You turn on the hot water and let it run for a few minutes.

01:41:10You might even light a candle and pour some essential oils into the water.

01:41:14Then in comes the liquid soap.

01:41:17You stir the water until the entire surface of the tub water is crammed with bubbles,

01:41:21and make your way in.

01:41:23The bubbles in a bubble bath have a fundamental primary function.

01:41:27Their job is to preserve the water's temperature, just so you can have warm water for longer.

01:41:33Do you have sweaty feet?

01:41:34Weird question, I know.

01:41:36But if you're one of these people, here's some good news.

01:41:39Trouble is not lost.

01:41:41Try putting a dry teabag inside your shoes and storing it in a dry place for a while.

01:41:47The teabags will absorb the humidity and the smell off the soles of your shoes.

01:41:51So here I am thinking, shouldn't we have learned these things in school?

01:41:55Well, either way, if you learned something new today, make sure to tell us about it in

01:42:00the comments below!

01:42:09These types of cheese have holes for a reason.

01:42:12For example, Swiss cheese is made with special bacteria that produce carbon dioxide.

01:42:17As the CO2 is emitted, it blows like bubblegum, leaving tiny craters, also known as cheese

01:42:24eyes.

01:42:25Then the cheese is cooled down, but the holes stay in place.

01:42:31Over 40 billion Oreos are made every single year.

01:42:34It's the world's most popular manufactured cookie.

01:42:38The geometric design stamped onto these cookies has the Nabisco logo, the symbol of European

01:42:43quality, surrounding the word Oreo.

01:42:46William Tournier created the chocolate cookie design we see today back in 1952.

01:42:54If you use reusable bottles, you probably know that sometimes they smell.

01:43:00Even if you only use it for regular water, it still smells.

01:43:04It's not the water that smells, it's the microorganisms in it.

01:43:08If you drink water from a bottle, the particles of your saliva and sweat stay in there.

01:43:13Those bacteria start to build up in the bottle, causing the smell.

01:43:17So if you choose reusable bottles, make sure to wash them every day to prevent those bacteria

01:43:23from building up.

01:43:24After washing, let it dry completely before using it again.

01:43:31Not only are the jeans blue, but the police officers' uniforms as well.

01:43:35The first official police officers appeared in the 19th century in London.

01:43:40They were given a blue uniform to contrast with the red and white uniform that military

01:43:44workers had already been wearing.

01:43:47Two decades afterward, the police force was adopted in the USA, and they followed the

01:43:51patterns.

01:43:52The uniform is still blue nowadays because it proved to be a good color.

01:43:57It's not that visible in dark hours, and police officers can observe things and people

01:44:02staying unnoticed.

01:44:03Also, stains aren't that visible on dark material.

01:44:07And well, everyone knows that police officers wear blue, and they're recognized it.

01:44:12So why change that?

01:44:16Baby carrots are tiny, and unlike regular carrots, wet.

01:44:20Not unlike baby humans.

01:44:22Baby carrots aren't some special sort of carrot.

01:44:25They're actually made of regular carrots by cutting off the skin and outer layers and

01:44:29then polishing them to look that pretty.

01:44:32The problem is, they can't retain moisture.

01:44:35A regular carrot retains some water inside because of the layers that lock it in.

01:44:39Once they're chopped out, baby carrots can dry out easily.

01:44:43So they usually sell them in bags with some water inside.

01:44:50Jeans have metal rivets, and they're there from the very beginning.

01:44:53Jacob Davis, the man who made the first pair of jeans, added copper rivets to spots where

01:44:58pants are more likely to rip – flies and pockets – to make them stronger.

01:45:03Today, they have more of a decorative purpose since they are distinctive and traditional

01:45:07for jeans.

01:45:09Another special thing about jeans is those tiny pockets they have that seemingly serve

01:45:14no purpose.

01:45:15Well, maybe it's true now.

01:45:17But years ago, when many cowboys were wearing jeans, the pocket was made specifically to

01:45:22keep a pocket watch there.

01:45:24Also, back then, a pair of jeans had just four pockets.

01:45:28That tiny pocket, the watch pocket, two big pockets in front, and just one pocket in the

01:45:33back.

01:45:36Car headrests are all about comfort, and detachable headrests are all about safety.

01:45:41If you pull the headrest out, you'll see two sturdy metal bars.

01:45:45If you ever get locked or trapped in a car, you can use the bars to smash the window and

01:45:50get out.

01:45:53Those little red spots you sometimes see after you crack an egg are nothing to be worried

01:45:58about.

01:45:59Tiny blood spots can be caused by a small rupture in a blood vessel of a hen as it was

01:46:04laying the egg.

01:46:05Eggs with these blood spots are safe to eat, but that spot can be removed if you want.

01:46:10It won't affect the taste of the egg.

01:46:12That's comforting.

01:46:15Hidden within the Toblerone logo of the mountain is the image of a bear standing on its hind

01:46:20legs, about to eat that yodeler over there.

01:46:23No, not really.

01:46:24This is because bears are a big part of Bern, one of the biggest cities in Switzerland where

01:46:29the founder created the triangular chocolate tree.

01:46:32Toblerone is also a play on the founder's family name, Tobler, and the Italian word

01:46:38Torrone, for honey and almond nougat.

01:46:43The space below a cup of noodles is there to protect the noodles during transport.

01:46:48This technique is called a middle suspension.

01:46:50Not only are they protected better in their styrofoam cup, but it also helps those noodles

01:46:55soften more evenly and quickly.

01:46:58Even though you might've noticed that the hole on the barrel of ballpoint pens has no

01:47:02purpose, it does.

01:47:04It's called a venting system, which helps the ink flow more smoothly.

01:47:08This way, an even amount of air pressure is created inside and outside the pen, allowing

01:47:13the ink to flow into the point easily.

01:47:17It's not an accident that soy sauce bottles have 2 spouts.

01:47:21The sauce is liquid, and it flows out of the bottle pretty quickly once you turn it over.

01:47:26Most Asian food lovers will admit they've spilled it at least once in a lifetime.

01:47:31That's why nowadays, restaurants prefer serving soy sauce in special bottles that have 2 spouts.

01:47:37This design allows you to control when and how much sauce will come out.

01:47:41Just put your finger on one spout while you pour the sauce through another.

01:47:45If you press your finger tightly to the spout, the sauce will stop flowing, and if you remove

01:47:50your finger, it will flow again.

01:47:52And please, do not remove your finger in a restaurant.

01:47:55It will freak everybody out.

01:47:59You've probably noticed that train and bus seats are covered in fabrics with weird patterns.

01:48:04Any idea why?

01:48:06They use these patterns to cover any germs and stains on the seat.

01:48:09Oh boy.

01:48:10The brighter the color and the more patterned it is, the harder it will be for a passenger

01:48:15to notice any stains and get grossed out.

01:48:17Also, the patterns are usually so ugly that no one even wants to look at them for long

01:48:22enough to spot any stains.

01:48:25So yeah, the pattern is there to make you look away, and if you look, to make it less

01:48:30noticeable.

01:48:31No bus will ever have plain white seats, that's a guarantee.

01:48:36The middle tab on soda cans can be flipped around.

01:48:39You can slip a straw in place so you don't have to hold it up your mouth.

01:48:43This stay-on tab replaced the pull-ring tab created in the early 60s.

01:48:47You remember those, don't you?

01:48:49Those could be quite sharp and easily discarded where they could be a menace for others.

01:48:54Now you can pop your straw straight into one.

01:48:57Also means you can produce some bubbles and make a mess like a 3-year-old.

01:49:02Sometimes when you purchase an article of clothing, you receive a plastic baggie with

01:49:07an extra button and a swatch of fabric.

01:49:10While the fabric is clearly used to patch holes, it can also be used to test the effects

01:49:15of various cleaners on certain surfaces.

01:49:17It's handy, too, to test wash cycles before using them to wash the whole garment.

01:49:25Escalators have those fluffy black brushes for a similar reason that some have yellow

01:49:29lines on their steps – to try and deter people from getting too close to dangerous

01:49:34places.

01:49:35People don't always take notice, and sometimes clothing can drape close to the point where

01:49:40the step meets the edge or skirt.

01:49:42The brush is a little barrier to help prevent this from happening.

01:49:46They can also catch bits of fluff and prevent other small things from falling down into

01:49:50the gaps.

01:49:53Those takeaway containers most associated with Chinese restaurants are designed to not

01:49:58only carry your food home, but to store it in the fridge.

01:50:02They double as a plate, as you can eat straight out of them and don't have to worry about

01:50:06dirty dishes.

01:50:08They were actually patented way back in 1894 to transport freshly shucked oysters and were

01:50:14known as oyster pails.

01:50:16They were later adapted to use as leak-proof containers for food.

01:50:22Ever wondered why coins have those little ridges along the edge?

01:50:25It's a leftover from earlier times when they were worth more.

01:50:28Counterfeiters could easily file the edges off to sell as gold or silver coins to make

01:50:33some profit.

01:50:34The ridges were created so it was much easier to tell which of the coins had been altered.

01:50:39It's not needed today, but the coins still have that altered style.

01:50:45All crackers and some cookies have holes to make sure the final product has the right

01:50:50texture.

01:50:51These teeny tiny holes allow steam to escape, so your crackers and cookies won't snap.

01:50:57If it weren't for these holes, also known as dockers, steam would build up inside the

01:51:01treat, and the final result might have been scrumptious, but it would've been rather

01:51:06oddly shaped.

01:51:09Dogs like to walk in circles before snoozing because they inherited this behavior pattern

01:51:13from their ancestors.

01:51:15There were no special doggy beds back then, so most pooches would have to push down tall

01:51:20grass to make a sort of snoozing spot.

01:51:22Plus, as a bonus, those movements scared off all the critters lurking in the vegetation.

01:51:30Donuts are ring-shaped for a similar reason.

01:51:32If they hadn't had holes right in the center, the dough there would've always been undercooked.

01:51:37By the way, they're often associated with the police because, back in the 1950s, donut

01:51:43shops were among the only places open late.

01:51:46They were a perfect place for police officers to grab something to eat and even deal with

01:51:50some paperwork during the night shift.

01:51:54Your jeans are blue on the outside and white on the inside because of a smart way to weave

01:51:59the fabric.

01:52:00The warp thread is dyed, while the weft thread has no color – it's just white.

01:52:06This way, manufacturers reduce the amount of dye needed for each piece of clothing.

01:52:11They're still dying to make the jeans.

01:52:18Tires on the landing gear don't burst because they're designed for a load that's four

01:52:22to five times as great as they experience during landing.

01:52:26The wheel itself might break, but the tire won't burst.

01:52:30This little tip based on people's psychology can help you choose the fastest line at the

01:52:34airport.

01:52:35If there are several lines at check-in, opt for the left one.

01:52:39It's believed that you will get to the counter more quickly this way.

01:52:43Most people are right-handed and intuitively choose the right side.

01:52:48Your skin usually becomes a bit dry during the flight.

01:52:52This happens because of low humidity levels in the cabin.

01:52:55Bring a good moisturizer with you to keep your skin hydrated on board.

01:53:00Do you know that airplane pilots always eat different meals before a flight?

01:53:05This way, if one of them gets food poisoning, the other will be able to take control of

01:53:09the plane.

01:53:11Airplane tray tables are some of the dirtiest surfaces in the cabin, so make sure to wash

01:53:15your hands frequently.

01:53:17And clean that table with an antibacterial wipe to get rid of all those bacteria living

01:53:21there.

01:53:22If you're sitting in an aisle seat, you can have more space to stretch your legs out.

01:53:27Just push the button on the underside of the outermost armrest.

01:53:31This will move the armrest up, giving you more space for your legs and preventing the

01:53:35armrest from jabbing into your side.

01:53:39Here's a reason why they turn the lights off in the cabin.

01:53:42Passengers need to get used to the darkness in case an emergency landing happens at night.

01:53:47This way, their eyes are already used to the absence of light, which makes it easier to

01:53:51evacuate.

01:53:53Flight attendants ask you to open window shades so they can see what's happening outside.

01:53:59This way, they can choose the best way to evacuate passengers in case of an emergency.

01:54:05Almost all passenger planes are white, since this color best reflects the sun's rays and

01:54:09prevents the plane from heating up.

01:54:12Another good reason is that white paint is cheaper.

01:54:15Also, workers and engineers can easily notice any damage on a white surface.

01:54:20It's better to avoid making important decisions during a flight.

01:54:25Your brain doesn't get enough oxygen at such heights.

01:54:28This negatively affects its functioning.

01:54:31Chewing gum, hard candies, and mints can help you to avoid this annoying ear-popping

01:54:36during take-off and landing, but not because of the candy itself.

01:54:40You feel better thanks to the process of swallowing.

01:54:44Yawning helps, too.

01:54:46As for the gum, it also helps get rid of that bad breath caused by the thin air at high

01:54:50altitudes, which pulls moisture right out of your body.

01:54:55Dry air can make you feel as if you're coming down with a cold.

01:54:58The air in the cabin dries out your nose and throat, as if you have symptoms of a cold.

01:55:03These symptoms usually go away right after landing.

01:55:07The water they use to make coffee and tea on board isn't always clean enough.

01:55:12Yeah, many companies use very good water filters now, but still, it's better to ask for bottled

01:55:18water if you're thirsty.

01:55:20That tiny triangle on the aircraft wall over your seat means a lot for flight attendants.

01:55:26These triangles mark the windows through which you can see flashing indicators.

01:55:31Those signal the retraction of the landing gears and the closing of the flaps.

01:55:35Let's say the pilots find out there's some problem.

01:55:37In that case, a flight attendant rushes to the necessary window to check what's happening.

01:55:43But for passengers, this is just the best place for photos, since you can see the wings

01:55:47perfectly.

01:55:48Seats in the middle of the cabin above the wings are the best for you if you have motion

01:55:52sickness.

01:55:54This area is more balanced and shakes the least during turbulence.

01:55:58If you tend to get nervous during the flight, do some physical exercise not long before

01:56:02boarding the plane.

01:56:04A little workout helps lower your stress levels and makes your body release endorphins, the

01:56:08happiness hormones.

01:56:09Also, this physical activity compensates for the hours you spend sitting still.

01:56:15The turbines are located under the wings, since this makes it cheaper, faster, and easier

01:56:20to service the engines.

01:56:22Previously, they used to be placed in the tail.

01:56:25It required expensive equipment and much more time to repair.

01:56:29When they started installing the engines below the wings, ticket prices went down.

01:56:34Imagine you're flying in a hot air balloon.

01:56:37See the burner system installed under the gas bag, also called the envelope?

01:56:41It heats the air inside, which makes the balloon go up.

01:56:44So, turbulence is the same hot air but created by nature.

01:56:49When the air heats up, it rises a plane.

01:56:51When it becomes cooler, the aircraft goes down.

01:56:55And passengers feel as if they're riding a roller coaster.

01:56:58A stream of hot air left by another plane can also cause turbulence.

01:57:02It's common for most flights, but usually, turbulence is so light that passengers don't feel it.

01:57:08Do you know that planes can fly even after one engine fails?

01:57:12Pilots can control such emergency situations and land the aircraft safely.

01:57:16Passengers may feel a slight tilt during the flight, but in most cases, they don't even

01:57:20know the plane is flying with only one engine.

01:57:23Your eyes get oxygen straight from the air.

01:57:26It's not delivered by the blood.

01:57:28So your eyes can feel somewhat dry during the flight.

01:57:31Put eyedrops in your bag.

01:57:32They'll help you keep your eyes moist.

01:57:34It's forbidden to carry large volumes of liquids on board because some hazardous substances

01:57:39can easily dissolve in water.

01:57:42If a plane has to land on water, its wings become a life-saving pillow.

01:57:46Empty fuel tanks help the aircraft stay afloat, too.

01:57:49By the way, it can be from 10 minutes to 60 hours before the plane sinks.

01:57:54It all depends on the model, weather conditions, and the pilot's skills.

01:57:58Those smiling flight attendants you meet when you get into the cabin usually hide their

01:58:02hands behind their bags.

01:58:04They're counting people entering the plane to make sure that all passengers are on board.

01:58:09Despite all the words people say about airplane food, it's not actually so bad.

01:58:13The problem is your sense of taste.

01:58:16It's not so acute since the air in the cabin makes your mouth dry.

01:58:19It also dulls your sense of smell.

01:58:21That's why airlines add a lot of spices and salt to their meals.

01:58:26Is it true that your hair grows faster during the flight?

01:58:29Not really.

01:58:30Scientists haven't managed to prove it.

01:58:32This myth appeared in the first part of the 20th century when some passengers noticed

01:58:36that their stubble had grown longer during the flight.

01:58:40It's normal for people to get headaches during the flight, especially right after takeoff.

01:58:44You climb to an altitude higher than Mount Everest within about 10 minutes.

01:58:49These changes happen too fast for your body to adjust.

01:58:53Seatbelts on planes stretch across your stomach to save you from getting slammed against the

01:58:57ceiling in case of turbulence.

01:58:59When it happens, the aircraft starts moving up and down, and your waist belt holds you

01:59:04securely.

01:59:06And seatbelts in cars protect people from horizontal collisions.

01:59:10Airplanes have special protection from lightning.

01:59:12Even if it strikes, passengers won't feel it.

01:59:15Airplanes are covered with an aluminum coating that conducts electric current but doesn't

01:59:20let it get inside the plane.

01:59:21Electronics and fuel tanks also have extra protection.

01:59:25Plane seats are so uncomfortable because airlines try to fit the maximum number of passengers

01:59:30on the plane.

01:59:31That's why there's so little space between seats.

01:59:35Two additional rows means 12 more passengers.

01:59:38Also, companies make airplane seats lighter to save on fuel costs.

01:59:43One seemingly insignificant extra weight can cost an airline thousands of dollars.

01:59:49And by the way, your seat has a fire-resistant coating.

01:59:52It's necessary to prevent a fire from spreading in case of an accident.

01:59:56Airport workers transport unclaimed luggage to special centers.

02:00:00If the owner doesn't show up within three months, the baggage is put up for sale in

02:00:05specialized stores.

02:00:07You couldn't use your phone on an airplane in the past since cell phones were really

02:00:10dangerous for navigation.

02:00:13Your radio signals could disrupt the settings in aircraft electronics.

02:00:17Oxygen masks fall down not only during strong turbulence, but also when the air pressure

02:00:22inside the cabin changes dramatically.

02:00:25Passengers are okay if they put on their oxygen masks, but in such cases are considered to

02:00:30be an emergency.

02:00:31And pilots do their best to quickly go down to a safe altitude so that passengers can

02:00:36breathe without oxygen masks.

02:00:40Imagine you're an art detective, and your task is to explore the mysteries behind the

02:00:45world's most famous paintings.

02:00:47I'm talking about works from Da Vinci, Michelangelo, Picasso.

02:00:52So grab your magnifying glass, as this journey is about to begin.

02:00:57First off on your list is Rome.

02:01:00After enjoying delicious pasta, you head to the Sistine Chapel, home to the world's most

02:01:05famous ceiling.

02:01:07Oh, and you know how they say Michelangelo painted the frescoes lying down?

02:01:11This is just a myth.

02:01:12Actually, the painter created a complex system of platforms that allowed him to paint standing.

02:01:19You're checking out the creation of Adam, that fresco in the middle.

02:01:23The Italian artist Michelangelo, the author of this masterpiece, was widely known for

02:01:27his study of human anatomy.

02:01:30Art experts argue that the right part of the painting is an anatomically correct depiction

02:01:35of an enlarged brain.

02:01:37To proof check this, you try overlapping a picture of the organ and the artwork.

02:01:42It seems to be a match.

02:01:44The cerebellum, the optic nerve, and the pituitary gland are all there.

02:01:49Even the floating green scarf thingy appears to match the vertebral artery.

02:01:54Some researchers think it was Michelangelo's way of depicting knowledge and wisdom, but

02:01:59you have to sleep on it to decide what you think.

02:02:02Moving on, you catch a train and arrive in Florence.

02:02:06Time for a quick gelato break, then straight to the Accademia Gallery.

02:02:11One of art's most celebrated sculptures is waiting for you inside, Michelangelo's David.

02:02:17David is a 17-foot tall marble wonder.

02:02:20It was carved for about three years.

02:02:23The mystery surrounding it is to figure out the statue's true expression.

02:02:27Looking at him from below, you'll think his face is serene and peaceful.

02:02:32But art historians argue that this work was largely misunderstood.

02:02:36Apparently, his body hides a very different story.

02:02:40Take a closer look, and you'll notice his brows are frowning, and the veins in his arms

02:02:46are popping out.

02:02:47That doesn't look too relaxed, does it?

02:02:50Michelangelo's idea was to depict David right before an important confrontation.

02:02:55So maybe he wasn't all that serene after all.

02:03:00Italy is so rich in art, you can't leave just yet.

02:03:04You're still in Florence.

02:03:05You pay a visit to the famous Uffizi Gallery.

02:03:09Many famous paintings are hosted by this museum.

02:03:12But you're checking out Botticelli's Primavera, or Spring.

02:03:17This artwork is mysterious from the get-go.

02:03:20Experts can't say the exact year it was commissioned.

02:03:23It remained untitled for years, until the painter Giorgio Vasari finally came up with

02:03:28a name for it.

02:03:30Usually, when critics and viewers admire this painting, they focus on the figures in the

02:03:34foreground.

02:03:36But in this case, the actual work lies in that Botticelli painted over 46 different

02:03:41plant species with almost identical precision.

02:03:45And oh, in the painting overall, these plant figures are repeated over 200 times.

02:03:51Unbelievable!

02:03:52I'd say the last visits were full of impressions, weren't they?

02:03:55Ready to keep going?

02:03:57A plane ride later, you arrive in Paris.

02:04:00The City of Lights, Paris, and the famous Mona Lisa.

02:04:05You go through the Museum de Louvre and come to Leonardo da Vinci's masterpiece, La Gioconda.

02:04:12There are many theories regarding this work of art, and you dive into some of them.

02:04:16A strong case has been made that the Mona Lisa could be a self-portrait of da Vinci

02:04:21himself.

02:04:22Historians have thoroughly compared da Vinci's face and that of the Mona Lisa, and guess

02:04:27what?

02:04:28They appear to be strikingly similar.

02:04:31Oh, and then there's the smirk theory.

02:04:34Dentist and art expert Joseph Bartowski claims to have discovered the secret behind Mona

02:04:39Lisa's smirk.

02:04:40He says her tight facial expression is a typical indication of someone who lost their front

02:04:46teeth.

02:04:47Could it be so?

02:04:49Also, in 2010, the Italian Committee for Cultural Heritage found a collection of symbols hidden

02:04:56in the painting.

02:04:57These are only visible through highly technological magnifying lenses, but they showed that Leonardo

02:05:03inscribed an LV inside Mona Lisa's right eye.

02:05:08Most guess that this is da Vinci's signature, but the other symbols, a CE in the left eye

02:05:15and a 72 in the arch of the background bridge, are still very mysterious.

02:05:21You covered a lot of ground on this one.

02:05:24Ah, of course, at the end of your visit, remember to test if her eyes really follow you around.

02:05:31Now you're headed to Amsterdam to check out the Rijksmuseum.

02:05:34You came to see a specific Rembrandt painting that hides a mysterious story.

02:05:39The Night Watch is one of Rembrandt's most famous paintings, but experts argue that the

02:05:44name of the painting and its content are mismatched.

02:05:48Let's take a closer look.

02:05:49The painting depicts a large group ready to embark on a mission.

02:05:54Rembrandt's technique is called chiaroscuro, highlighting the contrast between light and

02:05:58shade.

02:05:59Until 1947, art critics believed the painter was depicting a nighttime scene, but when

02:06:06the painting was cleared of a thick dust layer, it became clear that the scene was happening

02:06:10in broad daylight, with the sun streaming down from the top left.

02:06:15Now it's too late to change its name to The Day Watch.

02:06:19While in Amsterdam, you find a museum dedicated to Van Gogh's art.

02:06:24Did you know that he painted over 900 paintings during an impressive period of only 10 years?

02:06:30Anyway, the Van Gogh Museum hosts the biggest collection of yellow sunflower paintings you'll

02:06:35probably see in your life.

02:06:37Actually, almost all of Van Gogh's paintings feature dominant yellow shades.

02:06:42This particularity of his art may be a result of how he saw the world.

02:06:47Some art experts have speculated that one of Van Gogh's remedies changed his color perception,

02:06:53making him see more yellow around him.

02:06:56Okay, so this trip just keeps getting better.

02:06:59The next stop on your list is the United Kingdom.

02:07:02Then, on to the National Gallery.

02:07:05You may spend hours looking at Jan van Eyck's painting Arnolfini Portrait and not see anything

02:07:11out of the ordinary.

02:07:12In the foreground, a couple holds hands and stares at the viewer.

02:07:17But if you zoom in on the mirror on the wall, you'll see two more people in the room.

02:07:23Art experts say the male figure in the painting has his hands raised to greet these two people

02:07:27seen in the mirror, and that one of the figures is Van Eyck himself.

02:07:32Oh, and that's not the only watermark the painter left.

02:07:35Above the mirror, you'll see his flamboyant signature.

02:07:39Jan van Eyck was here, 1434.

02:07:43And speaking of people trying to sneak into their art, Caravaggio, the renowned Italian

02:07:48Renaissance painter, left a little Easter egg in one of his famous paintings, Bacchus.

02:07:53This one is a bit difficult to spot.

02:07:56In the half-filled jar in the bottom left corner of the painting, there is a tiny self-portrait

02:08:00of the painter himself, hidden amongst the liquid.

02:08:04To see the image clearly, one needs the help of sophisticated technology, or at least a

02:08:09very efficient magnifying lens.

02:08:10But it's there, a male figure, aka Caravaggio, with a brush in his hand.

02:08:17Fun fact, the tiny self-portrait was first noticed in 1922, over 300 years after the

02:08:23painting was completed.

02:08:25It was forgotten due to poor conservation.

02:08:28To finish the trip, you fly overseas across the Atlantic, all the way to Chicago.

02:08:34The enormous collection of the Art Institute hosts a well-known painting by Pablo Picasso,

02:08:39The Old Guitarist.

02:08:41This painting's secret is so well-hidden that it also needs the help of x-ray machines and

02:08:46super fancy technology.

02:08:48But the results are worth it.

02:08:50The readings show that Picasso painted The Old Guitarist on top of another unfinished

02:08:55painting.

02:08:56We can clearly see the outlines and shapes of a half-drawn female figure that Picasso

02:09:02gave up on mid-work.

02:09:04The emerging artists of the time used that way of saving money quite often, as canvases

02:09:09were expensive.

02:09:12This was quite a tiring world trip, wasn't it?

02:09:15Get some rest, Sherlock of Art!

02:09:18Have you ever stopped to think about the thrilling secrets of day-to-day modern life

02:09:23on planet Earth?

02:09:24I'm talking about tiny windows and washing machines, and little holes in airplane windows.

02:09:31If you haven't got a clue of what I'm talking about, tag along and allow yourself to be

02:09:36as surprised as I was when I found out!

02:09:40Remember the drawer at the bottom of your oven?

02:09:43Maybe you've been ignoring it all along, or using it to store pots and pans.

02:09:48Well, even though it can serve this function, that's not the only thing it's there for.

02:09:53The best way to use the bottom drawer is to keep your meal heated while you're waiting

02:09:57to serve it.

02:09:58Genius, right?

02:10:01Talking about secret doors, have you noticed that most washing machines have little flap

02:10:06doors at the bottom too?

02:10:08These doors actually serve as drain traps.

02:10:11It's where all the items that we put to wash together with our jeans and jackets go to.

02:10:17It's a type of collector, let's say, of small items.

02:10:21It stops them from getting into the main drain pipes and clogging them.

02:10:25It saves us hundreds of dollars in repairs each month.

02:10:29Now, who hasn't gone through the confusing task of having to measure how much pasta to

02:10:35cook for one serving?

02:10:36Well, here's the solution.

02:10:39The holes in the center of pasta spoons.

02:10:42They were actually made for measuring the exact amount of dry pasta you need for one

02:10:46serving.

02:10:48If you try stuffing wet cooked pasta through it, well, good luck with that.

02:10:54On a similar topic, have you ever wondered why pen caps have holes in them?

02:10:59Maybe you thought it was a design feature to regulate air pressure.

02:11:03But in reality, these holes have a much simpler and more important function – to reduce

02:11:08the risk of choking.

02:11:11Lots of people love to bite on their caps, and this tiny hole prevents them from choking

02:11:16in case they accidentally swallow a cap and it gets stuck in their throat.

02:11:21For kitchen lovers, there's a hidden secret right in front of your eyes that can change

02:11:25your life.

02:11:27Think pans, now think handles.

02:11:29Right, they have holes in them!

02:11:32As it turns out, these holes were designed to hold the spoon you're using for cooking.

02:11:37And instead of dripping sauce all over the stove or your kitchen floor, you can place

02:11:42the spoon in the hole and let it drip the sauce directly back into the pan.

02:11:49Speaking of everyday items, and I was, most doorknobs are made of brass because this material

02:11:56makes them naturally germ-free.

02:11:59Unlike plastic ones, brass doorknobs are kind of magical.

02:12:03They can disinfect themselves without you having to clean them.

02:12:07Neat, right?

02:12:09Have you ever noticed that at the bottom of a measuring tape, there is a little dip?

02:12:14You can find it in that metallic part you need to pull on to measure something.

02:12:19Well, that dip is actually the exact size of a regular nail.

02:12:24It was designed for people to place the tape on top of a nail and use it as a support while

02:12:29they stretch the tape.

02:12:31Well, I can't wait to try it out for myself!

02:12:35As for the margins in your notebook, they were invented to protect people's notes

02:12:39from mice.

02:12:41No, the mice weren't copying your answers for the math quiz.

02:12:45Actually, there were times when people had to cohabitate with rats and mice that often

02:12:51chewed on paper.

02:12:53So to prevent information from getting completely lost, people created margins.

02:12:59This way, texts were moved closer to the middle of pages and remained unharmed by rodents.

02:13:06Perhaps this is where to-digest information came from.

02:13:11And what about those tiny holes at the bottom of airplane windows?

02:13:16They have an extremely important function of regulating the air pressure inside the

02:13:21cabin.

02:13:22In other words, they help planes fly high up in the sky.

02:13:26Big responsibility, right?

02:13:29By the way, tray tables on an airplane are the germiest places inside the entire cabin.

02:13:35Studies showed that the trays had 8 times the amount of germs on the toilet flush button.

02:13:42Now, how about we cut a commercial airplane in half and see what's inside?

02:13:48Well, it would look more or less like this – rows of seats on top and everything else

02:13:53that needs to be stored at the bottom.

02:13:56I'm talking about passengers' luggage, emergency supplies, parts of the wing system,

02:14:01and so on.

02:14:04Moving on to bowling balls.

02:14:05Yes, I know it's a clumsy transition.

02:14:09Anyway, have you ever wondered what the insides of a bowling ball look like?

02:14:14If you have cut a professional ball in two, you'll see a familiar shape.

02:14:19Look closely, do you see it?

02:14:21Doesn't that look like the logo of Brightside?

02:14:24Anyway, professional bowling balls are different from the ones in your local bowling alley.

02:14:29That's because they're designed to make fancy moves.

02:14:33They actually have some really complex engineering inside.

02:14:36They're shaped to help skilled professionals get more strikes.

02:14:40The weight of professional bowling balls is designed to be projected inward as they travel

02:14:45down the bowling lane.

02:14:47This makes it harder for them to get into the gutters on the sides of the lane.

02:14:52Speaking of balls, let's take a look inside a baseball.

02:14:57To make it light and aerodynamic, producers use several different layers.

02:15:02Starting from the core, we have a cork center enveloped by black rubber.

02:15:07Then there's a layer of red rubber followed by two or three alternating layers of wool

02:15:12yarn.

02:15:13After that, there's a visible white leather cover and that beautiful red seam on the side,

02:15:19stitching it all together.

02:15:22And what if you had X-ray vision and managed to look inside a human bone?

02:15:27Spooky!

02:15:28I'd say what calls most attention is this spiderweb-like situation at the center of

02:15:34the ball.

02:15:35In reality, it's a highly condensed and complex structure of nerves that you have

02:15:40inside your bones.

02:15:42Aren't you lucky?

02:15:45Now I've got a riddle for you.

02:15:46What is round, can be found near the ocean, and looks like an aerial view of the Guggenheim

02:15:52Museum in New York City – the one that's made almost entirely of ramps.

02:15:57If you said a nautilus shell, then you guessed right!

02:16:01A nautilus is a shellfish whose house you can find in countless souvenir stores near

02:16:06the beach.

02:16:08It's made up of two layers – a matte white outer layer and an iridescent white inner

02:16:13layer.

02:16:14And if you were to cut it in half, it would look very similar to the insides of the Guggenheim

02:16:20Museum.

02:16:22Aloe leaves are good for healing purposes and also for hydration.

02:16:26But if you managed to look inside of an aloe leaf, the image you'd see would be satisfying

02:16:32and very relaxing.

02:16:34Who hasn't dreamed of a pool filled with jelly?

02:16:39There seems to be nothing more mundane and regular than a tube of toothpaste.

02:16:44But you wouldn't think so if you cut open a tube that contains several colors.

02:16:49Now there have been speculations that the insides of such a toothpaste tube might be

02:16:54divided by barriers so that the stripes don't mix.

02:16:58If you cut it in half, you'll see that it has only one interior chamber.

02:17:04As it happens, there's a lot of science behind the making of striped toothpaste.

02:17:09According to a specialist, they have to ensure that the paste in all the stripes has the

02:17:14same physical properties.

02:17:16This way, the colors are naturally prevented from mixing with one another.

02:17:20That's why, if you tear a tube open, you'll see something that looks like several slices

02:17:25of pizza in different colors.

02:17:28If you open your closet, you're bound to find at least a few wooden hangers.

02:17:33Usually they're made of cedar wood, which is a natural moth repellent.

02:17:38So cedar hangers actually protect your clothes from moth infestation.

02:17:43For some people, more than others, eyeliner is an everyday must, boy isn't it?

02:17:49But did you know that back in ancient Egyptian times, both men and women used coral eyeliners

02:17:56to protect their eyes from the sun's glare?

02:17:59Way to go for the Egyptians for figuring that out!

02:18:02Now if I could just learn to walk like one…

02:18:05Normally, we use headrests for the purpose of, well, resting our heads, right?

02:18:12Well, not only.

02:18:14As it turns out, headrests can be easily removed from the seats and used to break car windows

02:18:20in case of emergencies.

02:18:23This one is a trick very few people know about.

02:18:26You probably place your doormat horizontally, like most of us do.

02:18:31But doormats serve the purpose of absorbing dirt from the soles of your shoes before you

02:18:36enter your home.

02:18:37So for this function to work as it's meant to, the best way to place a doormat is vertically.

02:18:44This way, you take more steps on the top of the doormat before entering your house.

02:18:51And last but not least…

02:18:52Now I don't want to be accusatory here, but you have probably been vacuuming your

02:18:57house the wrong way, and I can prove it.

02:19:01Most people just vacuum floors and carpets in one direction or move the brush back and

02:19:06forth several times, thinking they've got all the dust out.

02:19:10But according to cleaning professionals, the best way to vacuum is in rows.

02:19:15First you go forward with the brush until you arrive at the end of the row.

02:19:20Then you fluff the carpet up and move back down along the same row, gathering the dust

02:19:25that wasn't collected in the first sweep.

02:19:27Talk about efficient cleaning!

02:19:30On the other hand, my idea of housecleaning is to sweep the room with a glance.

02:19:35Hey, I don't want to disturb that protective layer of dust.

02:19:40You're heading to a supermarket to get a few small items.

02:19:45The self-service checkout is way faster than waiting for people to unload their huge shopping

02:19:50carts.

02:19:51But this loud voice from a machine, commanding over and over again, spoils all the appetite.

02:19:58I have some good news for you.

02:20:00You can turn it off.

02:20:02Take a closer look at the screen.

02:20:04You'll probably see a volume button at the bottom.

02:20:08Use your finger to mute the annoying polite voice once and for all.

02:20:13Not all machines have this hidden option though, but it's definitely worth checking out.

02:20:19Usually a sunflower oil bottle has this weird inner cap.

02:20:24Most people remove the entire top layer and throw it away.

02:20:28But there's actually a better way to use it.

02:20:31Turn the removed element inside, down, and put it into the bottleneck.

02:20:36It will make a great dispenser.

02:20:38And you'll never spill more oil than you wanted in your salad.

02:20:43Planning a picnic with your friends in the wild?

02:20:46Forget about the classic picnic basket.

02:20:48We got it all wrong.

02:20:50It's not a basket, but a bucket.

02:20:52Yep, it's way better to put your picnic stuff into several buckets.

02:20:57This will help evenly distribute the weight among all guests.

02:21:01And when you find a nice spot for your picnic and get all the stuff out, turn the buckets

02:21:06over and use them as stools.

02:21:09When the food is over, put the buckets into each other to save space on the way back home.

02:21:15Your toast is getting burnt, but you don't have any kitchen tongs at hand?

02:21:20Take two identical forks.

02:21:22Put them together time to time.

02:21:25Stick them tightly with a rubber band.

02:21:27And voila, your tongs are ready.

02:21:30Ever wondered what this double bottom under the Nutella lid is for?

02:21:34There's only one way to find out.

02:21:36Here's a brand new Nutella jar.

02:21:39Let's remove the white carton circle and then peel off the foil.

02:21:43Surprise!

02:21:44There should be a little knife to cut the gold foil cover.

02:21:47Now you know how to get access to your favorite guilty pleasure without scratching your hands.

02:21:54Don't throw away the glass jar after you're done with Nutella.

02:21:57It can turn into a candle holder or a lantern.

02:22:01Wash it.

02:22:02Paint it to your taste.

02:22:03Add some decorations or lettering.

02:22:06Glue a decorative rope around the neck of the jar.

02:22:10Set a candle inside the jar or put string lights inside it.

02:22:14No one will ever guess that it used to be a Nutella jar.

02:22:18It'll be our secret.

02:22:21Have you ever wondered why Ritz crackers have ridges?

02:22:25You can use them as a safe knife for cheese and similar soft products like cucumber, ham,

02:22:31and so on.

02:22:33Just roll the cracker as if it were a tiny pizza cutter and press.

02:22:38Now all the ingredients fit on your cracker perfectly.

02:22:41Enjoy your snack.

02:22:43Do you have one of those old baking trays that you never use but still hesitate to throw

02:22:48away?

02:22:49Good news.

02:22:50You can recycle it and make a gorgeous frame for a painting or a picture.

02:22:55There are two ways to do so.

02:22:57Degrease the surface of your tray and attach the image to the bottom.

02:23:02In this case, the frame will stick forward.

02:23:05Or you can flip the tray upside down and the edges will hide behind.

02:23:10Hang this construction on a wall or put it on a shelf.

02:23:14And feel free to use metal paint to give your frame an appropriate color.

02:23:20An old cutting board can make a great frame for a mirror.

02:23:24Use double-sided tape to attach a matching mirror to the surface of your board.

02:23:29Make sure the mirror is firmly glued.

02:23:32And now you can hang it on a wall using the board's handle.

02:23:36Or put it on a cabinet and lean it on a wall.

02:23:39Don't forget to wash and dry the cutting board before beginning this DIY.

02:23:44We don't want the mirror to smell fishy.

02:23:47Another superpower of a cutting board is keeping wires tangle-free.

02:23:52Wrap some string lights around an old wooden cutting board and put it in your closet.

02:23:57The next holiday season, you'll have it completely untangled.

02:24:02A hairdryer can make a great mini vacuum cleaner when you need an emergency cleaning.

02:24:08Cut a plastic bottle and dry it.

02:24:11Put a layer of fabric on the fan of your hairdryer.

02:24:15Then place the fan in the plastic bottle bottom portion.

02:24:19Fix the bottle and attach it to the hairdryer using a plaster.

02:24:23Turn it on and you're ready to clean the mess.

02:24:26You can use a retro gas stove grate to hang your indoor plants.

02:24:31Attach it to the wall with screws or nails.

02:24:34Now you're ready to hang flower pots, string lights, and any other decor items.

02:24:40If the color of your stove grate doesn't match the interior,

02:24:43you can always fix this using spray paint.

02:24:47Chopsticks and wooden ice cream sticks can also turn into a beautiful panel

02:24:52that will decorate your interior.

02:24:54Glue the edges together to create a grid.

02:24:57You can also put together your name or any other word you want out of sticks.

02:25:03Then wrap the grid around with string lights and enjoy your decor.

02:25:08Don't throw away wrinkled kitchen foil.

02:25:10It can help to sparkle up your day.

02:25:13Crumple identical foil balls and glue them over a glass, a mirror frame,

02:25:18or even a book, and your life will immediately become more glamorous.

02:25:23If you need to sharpen your dull scissors, take aluminum foil

02:25:27and crunch it up into a ball.

02:25:30Sharpen the edges of the scissors right on that ball of foil.

02:25:34To speed up your ironing routine, place sheets of tinfoil

02:25:38under your ironing board and then put the cover back on.

02:25:42The tinfoil will reflect the heat.

02:25:44The iron will get hotter and will do the job much faster.

02:25:49If you struggle to organize all your jewelry

02:25:52and lose your favorite items from time to time, use a sponge to store it.

02:25:57Just make a few cuts and put your shiny little friends inside these cuts.

02:26:02They will sit firmly in the sponge and won't fall out or mix.

02:26:07You can also use a sponge to create an organizer for your jewelry.

02:26:12Find a cute box, cut your sponge into matching pieces,

02:26:15and put them inside the box.

02:26:18Use glue or tape to attach the sponge to the box

02:26:22and enjoy your new jewelry casket.

02:26:25You can easily make chocolate-filled strawberries at home.

02:26:29Take a plastic syringe, fill it with chocolate paste,

02:26:32remove the leaves from a strawberry, and stick the syringe

02:26:36into the hole from which the sprig usually sticks out.

02:26:40Squeeze chocolate into the berry and it's ready.

02:26:43You can use the same technique when you bake eclairs, apples,

02:26:47or want to leave a chocolate note on a pancake

02:26:50to surprise your significant other in the morning.

02:26:54Wooden pants hangers with metal clips can

02:26:56be handy when it comes to hanging curtains or a backdrop for your photo

02:27:00shoot.

02:27:01If you need to hang curtains but don't have any special hooks,

02:27:05attach several plants hangers along the entire length of the curtains

02:27:09and then hang this construction on a ledge.

02:27:13An old metal tea jar serves as a mini shelf

02:27:16for small things in your kitchen.

02:27:18Apply double-sided tape to the jar and stick it

02:27:21to the top corner of your cabinet.

02:27:24There's nothing better than a nice piece of buttered toast

02:27:27for breakfast, if we're not counting hot fudge sundaes.

02:27:30But if you find it harder to spread out cold butter over your toast,

02:27:34here's an idea.

02:27:36Use a cheese grater.

02:27:37Figure out the amount you need and grate the product.

02:27:40The process will also soften the butter, making it easier to spread,

02:27:44and you won't have to melt a too large amount of it in the process.

02:27:48But still, that hot fudge.

02:27:51Dried pasta comes in all sorts of different shapes and sizes for a reason.

02:27:55That's because each type of pasta goes best with a particular sauce.

02:28:00Pasta shells, for example, are perfect with denser and chunkier sauces.

02:28:04Why?

02:28:05Because the sauce gets inside the shells,

02:28:08making it easier to serve and eat the dish.

02:28:11The ribbed outer surface also helps with covering the shells in the sauce.

02:28:16If you ever end up burning your cookies,

02:28:19you can save them with your trusty grater, too.

02:28:22Just grate off the blackened parts after carefully taking

02:28:25the cookies from the baking tray.

02:28:27But be careful and wait until the cookies have cooled down.

02:28:30Also, if you ruin their shape a bit, you can always

02:28:33dip them in some melted chocolate.

02:28:36After the chocolate cools down, you'll have perfectly shaped cookies.

02:28:40Although, after it gets past your lips and beyond,

02:28:43does the shape of the cookie actually matter?

02:28:46Just saying.

02:28:49If you like adding a lot of ingredients to your sandwiches

02:28:52but don't really appreciate it when the bread gets soggy,

02:28:55there is a way to reduce the amount of moisture.

02:28:58Pick your sliced tomatoes or cucumbers and place them between two paper

02:29:02towels for up to five minutes.

02:29:04After that, you can use them.

02:29:06Also, make sure to spread butter, cheese, or sauces like mayo or ketchup

02:29:11onto the bread first.

02:29:12This will help you seal the bread and keep moisture at bay.

02:29:17Some people think that the little white string that you find near an egg yolk

02:29:21needs to be removed before you cook the egg.

02:29:24Well, I'm here to tell you that these strands are called chalaza,

02:29:27and you don't actually need to get rid of them.

02:29:30They help keep the yolk in place at the egg's center.

02:29:33A chalaza is not going to mess up the consistency or the taste of your food,

02:29:37so removing it is completely up to you.

02:29:41Ever notice that most juice boxes come with two flaps, one on each side?

02:29:46Those are actually handles.

02:29:47Manufacturers design the boxes this way to make it easier for us to hold them.

02:29:52This way, we don't end up squeezing the box, making the juice spill out.

02:29:58Now, you don't need to be a baking pro to know that you can use both white

02:30:02and brown sugar in your recipes.

02:30:04But have you ever wondered what the difference between these two is?

02:30:08It turns out that the only thing that sets them apart

02:30:11is that, during production, a small amount of molasses

02:30:15is added to the brown sugar.

02:30:17Molasses is basically a sort of syrup you get when processing sugarcane.

02:30:22It's usually removed during the refining process.

02:30:25That's how white sugar is produced.

02:30:27But if some amount of molasses remains in the final product,

02:30:31we end up with brown sugar, with its specific taste and darker hue.

02:30:35It's a good thing.

02:30:38There are a lot of things you can put in your dishwasher apart from your dishes.

02:30:42For example, you can clean such things as your silicone oven mitts

02:30:46or the knobs of some kitchen appliances, like your oven or stove.

02:30:51Some kitchen sponges and reusable towels may be safe to clean in the dishwasher

02:30:55as well.

02:30:57Speaking of kitchen cleaning products, there are a lot of things

02:31:00you can do with dish soap, like de-griming your patio furniture.

02:31:04Just add a bit of dish detergent to some warm water

02:31:07and use the solution to wipe down your outdoor furniture

02:31:10with a piece of cloth.

02:31:12Finally, rinse it clean using your garden hose.

02:31:16You can also use dish soap to get rid of greasy stains on your clothes,

02:31:20be it pasta sauce or salad dressings.

02:31:22Hey, sometimes we miss our mouths.

02:31:25So just apply a little dish detergent to the stain and then rinse with water.

02:31:30Use non-colored soap for lighter clothes.

02:31:32For more difficult stains, let the dish soap sink in for a bit,

02:31:36then throw the piece of clothing in the washer as usual.

02:31:38And think about maybe getting a bib.

02:31:42If none of the methods have helped you organize your closet

02:31:45and you're still overwhelmed with large piles of clothes,

02:31:48there's a simple way that might be effective.

02:31:51It's called the one-in, one-out rule.

02:31:54That means for every new piece of clothing you buy,

02:31:57you need to get rid of one you already have.

02:32:00That means you'll always be de-cluttering your space.

02:32:03To make it easier to find something in your closet, good luck!

02:32:07Keep your most-used items at eye level.

02:32:10This way they'll be easier to find and pull out when you're in a hurry.

02:32:14Those items that you tend to use less often,

02:32:16like your evening clothes, for example,

02:32:18can stay on the shelves above or below your eye level.

02:32:23You can make good use of old spice tins.

02:32:25If you glue some powerful magnets to the inside of the tins,

02:32:28they can double as magnetic shelves.

02:32:31You can use them for all sorts of everyday items,

02:32:34like kitchen pliers, ice cream scoops, or even cutlery.

02:32:38You can also place them on any metallic surface,

02:32:41like your refrigerator door.

02:32:43They'll blend in nicely with your kitchen magnets.

02:32:46Hidden in your laundry room, there's a great tool for picking up pet hair.

02:32:51It sometimes works better than lint rollers.

02:32:54Take a dryer sheet and, using some elbow grease,

02:32:57you'll get rid of that dog or cat hair in no time.

02:33:00It works on all sorts of surfaces,

02:33:02but it's especially effective for upholstered furniture.

02:33:06If you don't like it when a door starts squeaking whenever you enter a room,

02:33:11get a bar of soap and rub it straight on the hinges.

02:33:14This will only help for a while, though,

02:33:16but it'll do the trick until you manage to get to a hardware store.

02:33:20And, you know, buy some oil.

02:33:23Have you ever noticed that, in some elevators,

02:33:25there's a star next to the number of a specific floor?

02:33:28No, it's not to indicate where my office is.

02:33:32It's there to point out where the nearest exit is.

02:33:35And it's not always on the first floor.

02:33:37It's most likely located on the floor closest to the street.

02:33:42Have you ever wondered why stop signs are red?

02:33:45Back in the day, they didn't actually have any particular color at all.

02:33:49Before the 1920s, they didn't even have a standardized shade.

02:33:54In 1922, though, someone came up with the octagon.

02:33:58But initially, it was painted yellow.

02:34:00All because the red coloring tended to fade out too quickly because of sun exposure.

02:34:05So yellow turned out to be the best option.

02:34:08It took another 30 years for fade-resistant enamel paint to be invented.

02:34:13We ended up changing the color of the stop sign back to red.

02:34:16After all, it's still the best color if you want something to be easily noticeable.

02:34:22Do you know there's a type of rose that can grow taller than people?

02:34:27According to the Guinness Book of World Records,

02:34:29the tallest rosebush ever found grew in Vienna, Austria.

02:34:33It was a staggering 28.5 feet tall.

02:34:36Yes, it arose to a great height.

02:34:40In the same way we all have unique patterns on our fingerprints,

02:34:43no two tigers have the same set of stripes.

02:34:46It makes it easier for people working with this feline species

02:34:49to distinguish one tiger from another.

02:34:52I'll bet you didn't know the White House has its own flower shop

02:34:56hidden in the basement of the building.

02:34:58It's supposed to provide flower arrangements for all sorts of events that take place there.

02:35:04It's probably no surprise that pizza has become an American staple dish

02:35:08despite its Italian origin.

02:35:11People in the US love it so much

02:35:13that they buy 350 slices of pizza every second in the States.

02:35:18Man, I'm not getting my fair share.

02:35:21To manage the huge demand for this delicious dish,

02:35:24around 17% of all restaurants in the US are pizzerias.

02:35:29Finally, there's a way to make lemon juice without the seeds getting into your beverage.

02:35:34Try cutting the fruit in two and squeezing it with a pair of kitchen tongs.

02:35:39The pointed end of the lemon should be facing down.

02:35:42The juice will flow down, but the seeds will remain inside the lemon.

02:35:46Ooh, lemony. It goes well with pizza.

02:35:51Have you ever wondered what these extra holes at the top of your running shoes are for?

02:35:56They're designed so that you can tie the shoes in multiple different ways.

02:36:00That's useful when you want to compensate for things

02:36:02such as a bad stride or even a damaged toe.

02:36:07Plus, you can change the look of your shoes the way you prefer.

02:36:12Many people use a dust jacket of their book as a bookmarker.

02:36:16No problem with that. It will save your book from bent page corners.

02:36:20But the primary purpose of a dust cover is to keep the book safe from distortions.

02:36:25For instance, if you spill juice or drop some of the food on your book while reading it.

02:36:31The Tic Tac dispenser has this little groove on its top,

02:36:35so you can dispense only one Tic Tac at a time.

02:36:38Even though, let's be honest here, nobody does that.

02:36:41Most of us just spill a whole bunch at once,

02:36:43and then we wiggle all those extra Tic Tacs back in.

02:36:48Those rubber bumps you see between the tire treads are there for your safety.

02:36:53The raised edges tell you what the minimum height of your tread is.

02:36:56If the bump and the edges are even,

02:36:59it's time for you to visit the tire shop as soon as possible.

02:37:03But if the bumps are well beneath the level of the edges, you're good to go.

02:37:08What about that black grating on the microwave window?

02:37:12It's something called a Faraday shield.

02:37:14And it's there to prevent microwaves from getting away

02:37:17and turning the entire room into a Faraday cage.

02:37:20If the microwaves escape, your meal won't cook properly either.

02:37:24So yep, the cage is not there to make it difficult for you to see your meal while it's cooking.

02:37:29It's keeping the electromagnetic energy inside.

02:37:34How about a wrench-compatible screwdriver?

02:37:37Cover your screwdriver with the end of your wrench and you can increase its torque.

02:37:41That's why the head of your screwdriver is designed the way it is.

02:37:45When you have odd angles, you can use this strategy.

02:37:49You've probably heard those myths,

02:37:51the blue side of the eraser can erase the pen.

02:37:54False.

02:37:55Its purpose is to erase a pencil.

02:37:57But in case you're writing something on heavier paper,

02:38:01the blue side can remove smudges you see after using the pink eraser too.

02:38:06Have you ever wondered why oranges in supermarkets mostly come in the red mesh bag?

02:38:12It's a trick to make this food look more orange and encourage you to make a purchase.

02:38:17An extra tip, don't throw away the mesh bag.

02:38:20Tie it up so you can have a small pot scrubber to clean your sink,

02:38:23kitchen, appliances and dishes.

02:38:28You can see golf balls don't have a perfectly round shape.

02:38:32Their surface is covered with many little dimples,

02:38:34something golf balls didn't always have.

02:38:37At one point, experienced golfers started noticing how through time,

02:38:41older balls with imperfections such as nicks and bumps could travel further.

02:38:47Such things create turbulence in the air around the golf ball,

02:38:51which eventually reduces drag.

02:38:54So, manufacturers started producing balls with dimples so they could go farther and faster.

02:39:01You might have noticed that sometimes there are ridges in toothpick tops.

02:39:05It's more hygienic because when you break that off,

02:39:07you can prop the toothpick up on it and it won't touch anything.

02:39:14Another safety feature you'll find, this time in your car,

02:39:17is a tab on your rear view mirror.

02:39:20With it, you can change the position of the mirror

02:39:22so you don't get blinded if there's a car behind you with its high beams on.

02:39:27So, this little tab helps you control the glare of lights coming from behind.

02:39:31This feature showed up in the 1930s,

02:39:33but in the early 1970s, it became a part of standard equipment in most trucks and cars.

02:39:41Do you see that tiny hole on your iPhone right next to the rear-facing camera?

02:39:46It's a microphone, and it's there so your phone can record sound

02:39:49as you turn your camera around.

02:39:53Some cables have a thick cylinder towards the end of the cord.

02:39:57It's called a ferrite core, or a choke.

02:40:00It's a magnetic iron oxide that stops high-frequency electromagnetic interference.

02:40:06For example, you know that annoying static noise you get

02:40:09if you bring your phone too close to a speaker?

02:40:12This interrupts your call, which is why cable cords with big cylinders

02:40:16are pretty useful because they prevent these things.

02:40:21Do you know why nearly all luggage bags and backpacks have two zippers?

02:40:25It's way more convenient and easier to open in that way.

02:40:29But not just that, you can also lock these two zippers together

02:40:32to keep the stuff inside your bags safer.

02:40:36You know how toilets at public spots like malls have those big gaps at the bottom?

02:40:42It's primarily for better circulation of air.

02:40:45This type of door also makes it easier to clean the toilet

02:40:48or check if it's occupied if you're standing in line.

02:40:52Other than that, if you get stuck there and the lock gets broken,

02:40:56you still have a way to escape. You can just crawl out.

02:41:01Ever notice those plastic end caps on utility knives?

02:41:05And they also have scales on them,

02:41:07which indicates you may use them multiple times but with sharp edges.

02:41:12You can separate the blades through these plastic end caps.

02:41:16Then you can move the slider and bring the sharp blade to the front.

02:41:20If you've ever taken a moment to examine a regular grocery cart,

02:41:24especially their fold-out section,

02:41:26you probably noticed those metal loops jutting out.

02:41:30They're designed to protect the items you carry in your cart.

02:41:34You can use them to hang bags with soft items.

02:41:37You don't want to accidentally squish with heavier products like bread

02:41:41or easily breakable things like eggs.

02:41:46Many coffee mugs come with curved notches on their bottom.

02:41:49When you're washing your mugs,

02:41:50put them against the rack at an angle in your dishwasher.

02:41:54This way, the water won't pool in there,

02:41:56so your favorite cup will be completely dry

02:41:58by the time you take it out of the dishwasher.

02:42:02If you're a McFlurry fan,

02:42:04you've probably noticed there's a square hole in the handle of the spoon.

02:42:08It's there so you can attach it to the special machine

02:42:10that mixes the ice cream and your favorite toppings together.

02:42:14The machine has a bar that slips into this square-shaped spoon

02:42:18and then thoroughly stirs it.

02:42:20And you get the spoon so they can minimize the mess during the process.

02:42:24Quite neat, wouldn't you say?

02:42:28A regular milk jug has a dent on one side.

02:42:31Some might see it as a random design decision,

02:42:34but a dent has several purposes.

02:42:37One of them is to get bigger if there's a gas buildup.

02:42:40This happens when your milk is spoiled,

02:42:43so you don't even have to try to check this out.

02:42:45Also, the dent is there so the jug doesn't burst if you accidentally drop it.

02:42:50The dent allows the expansion space that deals with the sudden pressure

02:42:54that happens when you drop the jug.

02:42:58Dental floss.

02:42:59Sure, it's important for your dental health,

02:43:01and it's easy to assume what you do with it.

02:43:04But dental floss is great in the kitchen as well

02:43:07because it's a very precise cake slicer.

02:43:10Way better than a regular knife.

02:43:14Most kitchen shears have a serrated opening

02:43:17right there at the center where the blades and handles meet.

02:43:20It's something you can use to trim difficult herbs

02:43:23such as rosemary, thyme, or chives.

02:43:26Because of this opening, you don't need to pick the leaves off by hand,

02:43:30but de-stem them in one motion.

02:43:34The majority of gelatin containers or single-serving yogurts

02:43:37come with a tinfoil lid.

02:43:39And in most cases, you can use this covering as a disposable spoon.

02:43:44Just peel away the covering, and after a couple of simple folds,

02:43:47you'll have a perfect little spoon for your midday snack.

02:43:52Over 40 billion Oreos are made every single year.

02:43:55It's the world's most popular manufactured cookie.

02:43:59The geometric design stamped into these cookies

02:44:01has the Nabisco logo, the symbol of European quality,

02:44:05surrounding the word Oreo.

02:44:07William Tournier created the chocolate cookie design we see today back in 1952.

02:44:13Headphone jacks might become a thing of the past

02:44:16because of wireless technology.

02:44:18But if you've seen one, you might have noticed the rings

02:44:21at the base of the plug.

02:44:23One ring means single sound playback.

02:44:25Two rings represent stereo sound in the left and right ear,

02:44:29while three rings means you've got stereo and a microphone built in.

02:44:33Now, the iconic orange, red, purple, yellow, and lime green rings of Froot Loops

02:44:39hide a deep secret within.

02:44:41They don't represent different fruit flavors.

02:44:44All those rings are the same fruit flavors blended together.

02:44:47The colors are just for show.

02:44:51The E in Dell's logo is at an angle

02:44:53because the founder, Michael Dell,

02:44:56wanted his technology to turn the world on its ear.

02:45:00A compass uses magnets to point to the magnetic North Pole.

02:45:03But it's not really North at all.

02:45:06The North Pole of a compass magnet points toward the North

02:45:09because the North and South attract.

02:45:11Earth's South magnetic pole is near the geographic North,

02:45:15while the North Pole is near Earth's geographic South.

02:45:19Confusing, isn't it?

02:45:21Those little red spots you sometimes see after you crack an egg

02:45:25are nothing to be worried about.

02:45:27Tiny blood spots can be caused by a small rupture in the blood vessel of the hen

02:45:31as it was laying the egg.

02:45:33Eggs with these blood spots are safe to eat,

02:45:36but that spot can be removed if you want.

02:45:38It won't affect the taste of the egg.

02:45:41That's comforting.

02:45:42Ketchup is a word taken from many cultures,

02:45:45like Chinese, Malay, and Indonesian.

02:45:48It originally meant a pickled fish sauce.

02:45:51Catsup is also an acceptable spelling used.

02:45:54However, ketchup is the most popular way it's spelled these days.

02:45:59Airbnb's logo isn't a bent paperclip as it may seem to be.

02:46:04Bello, as it's called for belonging, means more than that.

02:46:08There's a person's head, the location symbol, and a heart for love.

02:46:12All joined together, they make Airbnb's iconic A and symbol of togetherness.

02:46:18E120, or Natural Red 4 food coloring, aka carmine,

02:46:23is made from tiny beetles.

02:46:25It's been used to color anything from cakes to candy to even drinks.

02:46:30That shine on candy also comes from bugs.

02:46:33This time, it's the Indian female lac bug.

02:46:37The beetle leaves behind a substance that is scraped from the trees

02:46:40to be formed into dry shellac that gives that glossy look.

02:46:45The Mozilla Firefox logo isn't a fox at all surrounding the planet.

02:46:50It's a red panda instead.

02:46:52The name Firefox is the English translation of its Chinese name.

02:46:57Those maintenance covers in the street are round for safety reasons.

02:47:01In past civilizations, like Ancient Rome, manholes – that's what they were called

02:47:06back then – were square-shaped slabs of stone.

02:47:09Unfortunately, these were prone to accidents.

02:47:12If they weren't placed properly, a square cover could slip through the square hole diagonally.

02:47:17Ow!

02:47:18Placing a round cover eliminated this problem.

02:47:21A circle cover won't slip inside because there are no angles.

02:47:26A tomato isn't technically a vegetable, but a fruit.

02:47:30Banana trees aren't related to palm trees or trees at all – they're herbs.

02:47:35Banana is considered an herb because it never builds a woody trunk the way a tree does.

02:47:40Instead, it forms a succulent stalk, like lemongrass or its cousin, ginger.

02:47:45You can call them berries as well.

02:47:48The Golden Gate Bridge color wasn't meant to be the orangey-red that it is today.

02:47:53The bridge's original color was suggested to be many other colors, such as black with

02:47:58yellow stripes or even candy cane to make it visible for passing ships and aircraft,

02:48:04especially in the frequent San Francisco fog.

02:48:08But when the steel arrived covered in an orange primer to protect it from rust, the architect

02:48:14preferred the international orange color, and it stuck.

02:48:19Those legs on the back of keyboards aren't an ergonomic design to help your wrists sit

02:48:23better.

02:48:25Using the legs out for too long can tire and hurt your wrists, plus slowing your typing

02:48:29down.

02:48:30The hinge legs are just there to help you see the letters and numbers better if you

02:48:34don't know how to touch type.

02:48:37The color of a chili pepper reveals nothing about its taste or heat.

02:48:42The smaller a chili is, the hotter it'll usually be.

02:48:46The heat doesn't come from the seeds, as believed, but the white membranes that hold

02:48:50them.

02:48:52Hidden within the Toblerone logo of the mountain is the image of a bear standing on its hind

02:48:57legs about to eat that yodeler over there.

02:49:00No, not really.

02:49:02This is because bears are a big part of Bern, one of the biggest cities in Switzerland where

02:49:06the founder created the triangle chocolate tree.

02:49:10Toblerone is also a play on the founder's family name, Tobler, and the Italian word

02:49:15Torrone, for honey and almond nougat.

02:49:18The space below a cup of noodles is there to protect the noodles during transport.

02:49:23This technique is called a middle suspension.

02:49:26Not only are they protected better in their styrofoam cup, but it also helps those noodles

02:49:31soften more evenly and quickly.

02:49:34Even though you might've thought that the hole in the barrel of a ballpoint pen had

02:49:38no purpose, it does!

02:49:41It's called a venting system, which helps the ink flow more smoothly.

02:49:45This way, an even amount of air pressure is created inside and outside the pen, allowing

02:49:51the ink to flow into the point easily.

02:49:54One of the most recognized logos in the cycling world has a hidden item in its famous logo.

02:50:00Inside the Tour de France name, a cyclist hides in the O, U, and R.

02:50:07Those metal brackets on the top of the nozzles in gas stations have a unique design put into

02:50:12place in case of accidents.

02:50:14If a dodo accidentally forgets the nozzle is still inside the gas tank and starts driving

02:50:20away, the magnetic brackets separate without damaging any part of the gas pump.

02:50:26Wendy's logo is designed off of the daughter of creator Dave Thomas.

02:50:30It's also named after her nickname, but there is more to the logo than that.

02:50:36Wendy's collar spells out the word mom.

02:50:39While unintentional, it became something to mean a homey feel, more than any other restaurant

02:50:44out there.

02:50:46Finding the right lane to be in while driving for your exit can sometimes be confusing,

02:50:51especially in a foreign country.

02:50:53Pay attention to the side of the road that exit signs are located.

02:50:57It'll be the lane you need to be in.

02:51:00Some toothpaste has a little seal on them that needs to be removed before you can use

02:51:05them.

02:51:06Instead of peeling back the foil layer, the toothpaste lid has a little spike on the top

02:51:11just for this reason.

02:51:14Tostitos have a secret symbol hidden right in the middle of their name.

02:51:18The two T's in the middle of the logo resemble two people enjoying tostitos over a bowl of

02:51:23salsa.

02:51:24The salsa bowl is in red and forms the dot in the I.

02:51:29One of the most recognizable figures in the world, the Statue of Liberty, for 16 years

02:51:34functioned as a fully operational lighthouse.

02:51:37However, the light was barely visible even from Manhattan.

02:51:42In 1901, it was eventually decommissioned as a lighthouse.

02:51:46Tourists could even visit the torch for a stunning view of the city.

02:51:50But an accident damaged the Statue of Liberty's torch in 1916, and it's been closed to the

02:51:55public ever since.

02:51:58The Do Not Remove Under Penalty of Law tag on mattresses isn't put there for the consumer

02:52:03or void your warranty either if you do remove them.

02:52:07In the 1900s, manufacturers used to create the filling with basically anything.

02:52:13Animal hair, old hospital beds, or clothing.

02:52:16It didn't matter at the time.

02:52:18Strict laws created the tags to stop recycled materials from being used and sold as new.

02:52:24Good thing!

02:52:25Toyota's symbol is more than just some random rings combined.

02:52:29The three overlapping ovals symbolize the merge of the hearts of consumers and Toyota

02:52:34together.

02:52:35A California sushi roll is made of seaweed, rice, cucumber, avocado, and crab meat.

02:52:43But it's not crab meat at all.

02:52:45Serrini is an imitation crab meat.

02:52:48It's made of white fish blended with sugar instead of crustaceans.

02:52:52The fish mixture is then heated and pressed into shape.

02:52:56The logo for Beats is just a lowercase b inside of a red circle.

02:53:00The circle represents a human head, with the b being the headphones in their shape.

02:53:06All those little black dots around the edges of car windows are called frits.

02:53:11A frit is a painted black enamel that's put into windshields during manufacturing.

02:53:16They block ultraviolet rays and help distribute temperatures between the metal and glass.

02:53:22There are 24 symbols hidden inside the Unilever logo.

02:53:25Let's count, shall we?

02:53:27The sun, dove, plant, spark, chili pepper, spoon, bowl, flower, ice cream, hand, hair,

02:53:37lips, swirl, fish, clothes, bee, particles, packaging, transformation, waves, DNA, palm

02:53:46trees, heart, and virtuous cycle.

02:53:51These represent everything that the company believes in and produces.

02:53:55DNA?

02:53:56Bobby pins are designed so that the zigzag part goes onto your scalp, not the flat part.

02:54:02It gives a greater grip on the hair and skin, making the pins stay in longer.

02:54:07The story that the pins were named after those fashionable London constables, called bobbies,

02:54:12is not true.

02:54:14I made it up.

02:54:16Ladies and gentlemen, please welcome our special guest today, the garbage bag.

02:54:21Canadian inventors created this irreplaceable household item about 70 years ago.

02:54:26Today, it comes in a huge variety of shapes, colors, and sizes.

02:54:30And if you think it can only serve one basic purpose, I have a big surprise for you.

02:54:35It can even prevent you from unwanted communication, but more on that later.

02:54:40What if I told you that you've been using your garbage bags wrong your entire life?

02:54:44If you take a closer look at it, you'll probably notice that the seam is inside out, and it's

02:54:49not by accident.

02:54:50In fact, you're not supposed to shake up the bag to open it.

02:54:54You gotta place the bag over a garbage can like a hat, and then just push the middle

02:54:58of the bag down to the can.

02:55:00No worries, you're not the only person who didn't know that.

02:55:03This eye-opening trick went viral online and got millions of views.

02:55:07Imagine that you need to dye your hair, paint walls, or mold a clay mug immediately, but

02:55:12you don't have a protective suit on hand.

02:55:14Here comes the good news.

02:55:16You can make one out of a plastic bag.

02:55:18It will take you less than a minute.

02:55:20Just find a bag wide enough to fit your torso.

02:55:22Cut one hole in the bottom of the bag for your head, and make two holes for the arms

02:55:26on the sides.

02:55:27Voila!

02:55:28Feel free to make a hat from another plastic bag to protect your hair.

02:55:32When the job is done, you can wash this handmade suit and reuse it.

02:55:36Our next hack is for those who don't like to waste money.

02:55:39You can use a real plastic bag instead of a raincoat that looks like a plastic bag anyway.

02:55:44Just make a round cut for your face, and you're ready to go.

02:55:47You can reuse it as many times as you want.

02:55:50You can use a plastic bottle to create a recycled bag dispenser.

02:55:54Take a large bottle.

02:55:55It can be either a bottle of soda or washing gel.

02:55:58What matters is its shape.

02:56:00It must be straight so you can easily store bags inside it.

02:56:04Wash the bottle, dry it, and cut off the bottleneck and bottom.

02:56:07Turn it upside down.

02:56:08There you go.

02:56:09Your bag dispenser is ready.

02:56:11You can use your imagination to paint and decorate your DIY project with stickers and

02:56:16lettering to your taste.

02:56:18When the design is ready, attach it to the back of the bottle and stick this holder to

02:56:22the wall in your kitchen or one of the cabinet doors.

02:56:25Imagine you've been planning a perfect hiking weekend for ages.

02:56:29But when you actually get there, it starts raining.

02:56:32Don't rush back home.

02:56:33Plastic bags will serve you well if you need to put your clothes or equipment on wet grass.

02:56:38Also, you can make an emergency sleeping bag cover using a large garbage bag.

02:56:42After the rain, it will serve as a nice mattress to lay under your sleeping bag to protect

02:56:46it from moisture and provide an additional layer for a cozy nap.

02:56:51Just fill the bag with some soft leaves and straw that lie on the ground, and there you go.

02:56:56A large garbage bag can be your best friend when you're camping with friends somewhere

02:57:00in the wild.

02:57:01You can turn it into a temporary handmade shower, toilet, or even a dressing room out of it.

02:57:07Just hang it on the tree, and no one will spy on you.

02:57:10If you went for a walk wearing a pair of your favorite shoes that get wet easily, here's

02:57:14an easy tip to keep your socks dry.

02:57:16Put plastic bags over your socks, tuck the edges of the bags into your socks or trousers,

02:57:21and then put your shoes on.

02:57:24There's one obvious drawback, though.

02:57:26Feet can slip inside the shoes, so be careful.

02:57:29These plastic socks are also handy when you're trying to put on tight jeans that usually

02:57:33make your feet stick inside them.

02:57:36Have you ever had your bag torn at the worst possible moment?

02:57:39A plastic bag with handles can become an emergency backpack.

02:57:42Just place your stuff inside the bag, put your hands through the handlers, and you're

02:57:46ready to go.

02:57:48A garbage bag is also a good material for book covers.

02:57:51You can reuse multicolored bags to create a unique pattern for your favorites.

02:57:56You're moving to a new house and packing all your belongings.

02:57:59Suddenly, you run out of boxes.

02:58:01Sounds familiar.

02:58:02No problem.

02:58:04Grab a package of large garbage bags and pack the remaining stuff.

02:58:07Unlike boxes, this packaging will protect your property from rain or snow.

02:58:12Garbage bags are especially good for packing blankets, pillows, and stuffed toys.

02:58:17If you need to make a vacuum packing for your clothes or stuffed toys, simply put your belongings

02:58:22in a trash bag, place a tube from your vacuum cleaner inside the bag, and then turn it on.

02:58:28The vacuum cleaner will remove all your excess hair from the bag, and you'll save space

02:58:32in your suitcase or basement.

02:58:35Someone really special has invited you home to cook a romantic dinner together.

02:58:39Finally, you want to show all your extraordinary cooking skills, but your special someone doesn't

02:58:44have an apron, and you don't want to mess up your new outfit.

02:58:47No worries.

02:58:48Make an emergency apron using a large garbage bag.

02:58:51It will surprise that special someone even more.

02:58:55Speaking of stylish outfits, are you familiar with the term garbage bag dress?

02:59:00Celebrities and famous fashion brands shock the audience with outfits looking like trash

02:59:04bags from time to time.

02:59:06Some of them actually make outfits using garbage bags like fabric.

02:59:10It's a popular option for young artists who can't afford to buy and use expensive fabrics.

02:59:15Garbage bags are very flexible, so they are a useful material for making patterns for

02:59:20future outfits.

02:59:21When it comes to garbage bags, the DIY project's possibilities are almost infinite.

02:59:27People use bags to make lampshades, clothes covers, small cosmetic bags, makeup organizers,

02:59:33recycled glasses, and whatnot.

02:59:35Some even weave baskets, bags, and floor rugs out of them.

02:59:39It's pretty easy to handcraft a rug.

02:59:41You need to cut several bags into equal strips and weave a long braid from these strips.

02:59:46Now twist this braid into a spiral and tire glue each layer together.

02:59:51To secure this entire construction from breaking, you can screw your rug on a sewing machine

02:59:55from the middle to the edges, as if you're drawing a star.

02:59:58This plastic braid can also serve as emergency laces, a rope, or a handmade ribbon for decorating

03:00:04gifts and flowers.

03:00:06Filmmaking is another yield where garbage bags can be real stars.

03:00:10If you're shooting indoors and the sunlight is too sharp, you can put white garbage bags

03:00:14on all windows to diffuse the light or to set the white balance.

03:00:18Black lightproof garbage bags may serve you as a shading curtain to get rid of the sunlight

03:00:22in the room whatsoever.

03:00:24Feel free to use a white bag to create a diffused light bulb.

03:00:27Inflate the bag like a balloon and put it next to a lamp, but make sure to use a LED

03:00:32light so it doesn't get too hot.

03:00:34Everyone knows that touching a plastic bag with a hot iron is a bad idea because it will

03:00:39melt, but this lets us create unique shapes from this colorful and affordable material.

03:00:45Want to make a unique designer vase?

03:00:47Take a bowl and cover it with paper tightly.

03:00:49Then wrap the matching strips of plastic bag around the bowl.

03:00:53Now place another layer of paper on the top and gently iron over the entire surface of

03:00:57the bowl.

03:00:58Voila!

03:00:59The plastic's melted and you've got a new stylish and eco-friendly vase.

03:01:04Garbage bags can produce very cool sound effects.
