00:00:00If you ever find yourself stuck in the trunk of your car, stay calm.
00:00:04All cars are supposed to be equipped with an emergency latch to help open the trunk
00:00:09from the inside in the unlikely case it happens.
00:00:12These latches are so well thought out that they can be opened by people of all ages.
00:00:17More so, handles are designed to glow in the dark, too.
00:00:21You can even pull them with the mouth if there's not enough wiggle room to use your hands.
00:00:25Never mind how you ended up in the trunk in the first place.
00:00:28Moving on…
00:00:30If you're ever working with needle and thread, remember you don't need to stick the needle
00:00:34directly into the spool.
00:00:36You may end up losing the needle altogether, not to mention you can easily hurt your fingers!
00:00:41A lot of modern sewing kits these days come with a designated place for safeguarding the
00:00:46needles.
00:00:47It's located at the bottom part of the thread spool.
00:00:50You'll just need to pull it out.
00:00:52It's even made to hold multiple sewing needles at a time.
00:00:56Several ballpoint pens come with a little secret of their own.
00:01:00Did you ever notice that in some of them, there's a small hole in the plastic part?
00:01:05It's actually a rudimentary ventilation system.
00:01:08It's supposed to let the ink easily make it to the tip of the pen.
00:01:12Okay, I know it's in the name, but you really don't need to shake the seasoning shaker
00:01:17to get any product out.
00:01:18Don't believe me?
00:01:20You're not the only one.
00:01:21Go grab your favorite seasoning bottle out of your pantry.
00:01:25If it has one of those removable plastic caps, it's perfect for the experiment.
00:01:30Instead of shaking the bottle, try holding it from the plastic cap while it's upside
00:01:35down.
00:01:36Now, gently twist the bottle from side to side and, before you know it, you get some
00:01:41gorgeously flowing seasoning without having to wiggle the shaker and make a mess all over
00:01:46the stove.
00:01:47On the same note, most salt and pepper shakers should have ridges on the bottom of the glass
00:01:53portion.
00:01:54In case you get any seasoning stuck in there, place the bottom of the salt shaker against
00:01:58the bottom of the pepper shaker and wiggle it around so the ridges click with each other.
00:02:04The seasoning should easily pour out now without you having to open the bottle.
00:02:09In colder weather, you often have so many clothing layers on you that you can hardly
00:02:13feel the purse or back straps on your shoulder anymore.
00:02:17Not to mention how fast they can slide off.
00:02:20Some jackets come with a built-in solution for that, in the form of a small tab on the
00:02:24shoulder with either a hook or a button.
00:02:27It's meant to be opened and closed comfortably, so you can keep your purse in place at any
00:02:32time.
00:02:33You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
00:02:39But you can use your vegetable peeler for chopping fine strips of onion as well.
00:02:45Just cut the onion into quarters vertically and then start slicing.
00:02:49This might also help out with those embarrassing onion tears.
00:02:53Most people miss this one, but should you ever have a closer look at your toothpaste
00:02:58tube, you will surely see some sort of coloring there – either a dot or a block.
00:03:04Colors can vary.
00:03:05They can be black, green, red, or even blue.
00:03:08These color spots are actually meant to help the assembly machines back at the toothpaste
00:03:12factory.
00:03:13They recognize when and where these machines need to cut the toothpaste tubes and proceed
00:03:18to fold them for packaging.
00:03:20For most types of footwear, if there's anything that seems a bit out of place, always know
00:03:25that it's there for a reason.
00:03:27Most manufacturers don't put extra items on shoes just for fun.
00:03:31It would definitely be a waste of time and resources.
00:03:34For footwear like boots, for example, there's often a small loop at the top back of the
00:03:39shoe.
00:03:40It's there to help you when you need to put the shoe on since you can quickly pull
00:03:44on it.
00:03:45Plus, you can also hang the shoes somewhere, most likely to dry, since most boots are meant
00:03:50to be worn in the colder weather.
00:03:52Now I've been guilty at least once of overdressing with a bunch of layers just so I won't need
00:03:58to jam everything in my check-in bag.
00:04:01But does it become a problem when you actually have to get seated?
00:04:04What do you do with your coat or your jacket?
00:04:07Well, have a closer look next time you board a plane on the seat in front of you.
00:04:12The hook that keeps the tray table upright can double as a jacket hook.
00:04:17As long as you don't need to have any meals while in the air, you're good to go.
00:04:22Most mascaras expire within 3-6 months, I'm told, depending on the manufacturer.
00:04:27But you can help speed up that process if you're not careful enough.
00:04:31Continuously pumping the mascara wand trying to mix in the product actually pushes more
00:04:37air into the tube.
00:04:38This can make it dry much faster, and you evidently won't get the desired results
00:04:43with it anymore.
00:04:44There's an easy way to check if your mascara is still good enough to use.
00:04:48If you don't hear a popping noise when you take the brush out, you may very well need
00:04:53to go get yourself a new mascara tube.
00:04:57Now I know we're living in the era of Bluetooth-connected devices, but for better quality sound, they
00:05:03still recommend using headphones that connect via audio jacks.
00:05:07Remember seeing black ridges on those jacks?
00:05:09They aren't there just to make them fit when you plug them into your phone or laptop.
00:05:15Made out of a special insulating material, these bands are meant to guard the wires when
00:05:20sound is being transmitted.
00:05:22Based on the number of bands, you can figure out which end goes where.
00:05:26Some empty space under noodles in a cup doesn't mean the company producing them wants to cheat
00:05:31you out of a full portion.
00:05:32No no!
00:05:34It's a manner of keeping the noodles intact during their transportation.
00:05:37It also helps with the circulation of hot water that is poured over the products before
00:05:42you can enjoy them.
00:05:44The V-shaped neckline was initially designed to serve a bunch of objectives.
00:05:48First, as a way of prolonging the life of the garment that would maintain its shape
00:05:52over the years.
00:05:54It's also there to fit your head through the shirt in case it needs some stretching.
00:05:58This way, it ensures a snugger grip around the neck.
00:06:01Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
00:06:07Now it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket
00:06:12with an additional mysterious pocket on the right side.
00:06:16Turns out, this pocket was used by men to easily reach their train tickets since most
00:06:21of them had to travel to work every day.
00:06:24It helped them keep their jacket buttoned up but also benefited from the use of a pocket.
00:06:29Now it's only added as a decoration, and it doesn't serve an actual purpose anymore.
00:06:35Speaking of things we don't use these days, or at least for their initial purpose, did
00:06:39you know Play-Doh was originally a cleaning product?
00:06:43In the 1920s, the market was in need of a product that could help them wipe the wallpapered
00:06:48areas around coal-burning furnaces.
00:06:51The recipe for what we now know as Play-Doh was thus invented.
00:06:55It was manufactured in white only, and was supposed to clean wallpaper by being rolled
00:07:00back and forth over the dirt.
00:07:03It was only later, in the 1940s, that new products for cleaning wallpaper were brought
00:07:07up, and Play-Doh was redirected toward another area of the market.
00:07:13Now while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean
00:07:18out the toaster?
00:07:19Well, not anymore, since I recently found out that toasters have a slide or a panel
00:07:25at the bottom that helps get rid of all those annoying breadcrumbs easily.
00:07:32Now there used to be a time when you could only have access to video games by inserting
00:07:37cartridges in your console of choice.
00:07:40These tiny objects gave many doctors a lot of headaches.
00:07:44People soon started popping up in hospitals after swallowing small game cartridges, especially
00:07:49the younger generation.
00:07:51Nintendo, the company that manufactures the majority of these devices, had to come up
00:07:56with a creative solution to prevent these accidents.
00:07:59So these days, Nintendo Switch cartridges are purposely coated with specific chemicals
00:08:05that can leave a really bad bitter taste in the mouth.
00:08:08Not that I'd recommend you ever try and taste for yourself.
00:08:13Over 40 billion Oreos are made every single year.
00:08:16It's the world's most popular manufactured cookie.
00:08:20The geometric design stamped into these cookies has the Nabisco logo, the symbol of European
00:08:25quality, surrounding the word Oreo.
00:08:28William Tournier created the chocolate cookie design we see today back in 1952.
00:08:35Headphone jacks might become a thing of the past because of wireless technology, but if
00:08:39you've seen one, you might've noticed the rings at the base of the plug.
00:08:44One ring means single-sound playback, two rings represent stereo sound in the left and
00:08:49right ear, while three rings means you've got stereo and a microphone built in.
00:08:55Now the iconic orange, red, purple, yellow, and lime green rings are Froot Loops.
00:09:00Hide a deep secret within.
00:09:02They don't represent different fruit flavors.
00:09:05All those rings are the same fruit flavors blended together.
00:09:08The colors are just for show.
00:09:12The E in Dell's logo is at an angle because the founder, Michael Dell, wanted his technology
00:09:18to turn the world on its ear.
00:09:21A compass uses magnets to point to the magnetic north pole, but it's not really north at all.
00:09:27The north pole of a compass magnet points toward the north because the north and south
00:09:32attract.
00:09:33Earth's south magnetic pole is near the geographic north, while the north pole is near Earth's
00:09:38geographic south.
00:09:40Confusing, isn't it?
00:09:42Those little red spots you sometimes see after you crack an egg are nothing to be worried
00:09:47about.
00:09:48Tiny blood spots can be caused by a small rupture in the blood vessel of the hen as
00:09:52it was laying the egg.
00:09:54Eggs with these blood spots are safe to eat, but that spot can be removed if you want.
00:09:59It won't affect the taste of the egg.
00:10:02That's comforting.
00:10:04Ketchup is a word taken from many cultures, like Chinese, Malay, and Indonesian.
00:10:10It originally meant a pickled fish sauce.
00:10:13Ketchup is also an acceptable spelling use, however, ketchup is the most popular way it's
00:10:18spelled these days.
00:10:20Airbnb's logo isn't a bent paperclip as it may seem to be.
00:10:25Bella, as it's called, for belonging, means more than that.
00:10:29There's a person's head, the location symbol, and a heart for love.
00:10:34All joined together, they make Airbnb's iconic A and symbol of togetherness.
00:10:40E120 or Natural Red 4 food coloring, aka carmine, is made from tiny beetles.
00:10:46It's been used to color anything from cakes to candy to even drinks.
00:10:52That shine on candy also comes from bugs.
00:10:55This time it's the Indian female lac bug.
00:10:58The beetle leaves behind a substance that is scraped from the trees to be formed into
00:11:03dry shellac that gives that glossy look.
00:11:07The Mozilla Firefox logo isn't a fox at all surrounding the planet.
00:11:12It's a red panda instead.
00:11:14The name Firefox is the English translation of its Chinese name.
00:11:18Those maintenance covers in the street are round for safety reasons.
00:11:22In past civilizations, like Ancient Rome, manholes, that's what they were called back
00:11:27then, were square-shaped slabs of stone.
00:11:30Unfortunately, these were prone to accidents.
00:11:33If they weren't placed properly, a square cover could slip through the square hole diagonally.
00:11:38Ow!
00:11:39Placing a round cover eliminated this problem.
00:11:42A circle cover won't slip inside because there are no angles.
00:11:47A tomato isn't technically a vegetable, but a fruit.
00:11:51Banana trees aren't related to palm trees or trees at all – they're herbs.
00:11:56Banana is considered an herb because it never builds a woody trunk the way a tree does.
00:12:01Instead, it forms a succulent stalk like lemongrass or its cousin, ginger.
00:12:07You can call them berries as well.
00:12:09The Golden Gate Bridge color wasn't meant to be the orangey-red that it is today.
00:12:14The bridge's original color was suggested to be many other colors, such as black with
00:12:19yellow stripes or even candy cane to make it visible for passing ships and aircraft,
00:12:25especially in the frequent San Francisco fog.
00:12:29But when the steel arrived covered in an orange primer to protect it from rust, the architect
00:12:35preferred the international orange color, and it stuck.
00:12:40Those legs on the back of keyboards aren't an ergonomic design to help your wrists sit
00:12:45better.
00:12:46Using the legs out for too long can tire and hurt your wrists, plus slowing your typing
00:12:50down.
00:12:51The hinge legs are just there to help you see the letters and numbers better if you
00:12:56don't know how to touch type.
00:12:59The color of a chili pepper reveals nothing about its taste or heat.
00:13:03The smaller a chili is, the hotter it'll usually be.
00:13:07The heat doesn't come from the seeds, as believed, but the white membranes that hold
00:13:12them.
00:13:13Hidden within the Toblerone logo of the mountain is the image of a bear standing on its hind
00:13:18legs about to eat that yodeler over there.
00:13:21No, not really.
00:13:23This is because bears are a big part of Bern, one of the biggest cities in Switzerland where
00:13:28the founder created the triangle chocolate tree.
00:13:31Toblerone is also a play on the founder's family name, Tobler, and the Italian word
00:13:36Turrone for honey and almond nougat.
00:13:39The space below a cup of noodles is there to protect the noodles during transport.
00:13:44This technique is called a middle suspension.
00:13:47Not only are they protected better in their styrofoam cup, but it also helps those noodles
00:13:52soften more evenly and quickly.
00:13:55Even though you might've thought that the hole in the barrel of a ballpoint pen had
00:14:00no purpose, it does!
00:14:02It's called a venting system, which helps the ink flow more smoothly.
00:14:07This way, an even amount of air pressure is created inside and outside the pen, allowing
00:14:12the ink to flow into the point easily.
00:14:15One of the most recognized logos in the cycling world has a hidden item in its famous logo.
00:14:22It's named after the Tour de France name – a cyclist hides in the O, U, and R.
00:14:28Those metal brackets on the top of the nozzles in gas stations have a unique design put into
00:14:33place in case of accidents.
00:14:35If a dodo accidentally forgets the nozzle is still inside the gas tank and starts driving
00:14:41away, the magnetic brackets separate without damaging any part of the gas pump.
00:14:47Wendy's logo is designed off of the daughter of creator Dave Thomas.
00:14:52It's also named after her nickname, but there is more to the logo than that.
00:14:57Wendy's collar spells out the word mom.
00:15:00While unintentional, it became something to mean a homey feel more than any other restaurant
00:15:05out there.
00:15:07Finding the right lane to be in while driving for your exit can sometimes be confusing,
00:15:12especially in a foreign country.
00:15:15Pay attention to the side of the road that exit signs are located – it'll be the
00:15:19lane you need to be in.
00:15:22Some toothpaste has a little seal on them that needs to be removed before you can use
00:15:26them.
00:15:27Instead of peeling back the foil layer, the toothpaste lid has a little spike on the top
00:15:32just for this reason.
00:15:35Tostitos have a secret symbol hidden right in the middle of their name.
00:15:39The two T's in the middle of the logo resemble two people enjoying Tostitos over a bowl of
00:15:45salsa.
00:15:46The salsa bowl is in red and forms the dot in the I.
00:15:50One of the most recognizable figures in the world, the Statue of Liberty, for 16 years
00:15:56functioned as a fully operational lighthouse.
00:15:59However, the light was barely visible even from Manhattan.
00:16:03In 1901, it was eventually decommissioned as a lighthouse.
00:16:07Tourists could even visit the torch for a stunning view of the city.
00:16:11But an accident damaged the Statue of Liberty's torch in 1916, and it's been closed to the
00:16:16public ever since.
00:16:19The Do Not Remove Under Penalty of Law tag on mattresses isn't put there for the consumer
00:16:24or void your warranty either if you do remove them.
00:16:28In the 1900s, manufacturers used to create the filling with basically anything – animal
00:16:34hair, old hospital beds, or clothing.
00:16:37It didn't matter at the time.
00:16:39Strict laws created the tags to stop recycled materials from being used and sold as new.
00:16:45Good thing!
00:16:46Toyota's symbol is more than just some random rings combined.
00:16:50The three overlapping ovals symbolize the merge of the hearts of consumers and Toyota
00:16:55together.
00:16:56A California sushi roll is made of seaweed, rice, cucumber, avocado, and crab meat.
00:17:04But it's not crab meat at all.
00:17:06Serrini is an imitation crab meat.
00:17:09It's made of white fish blended with sugar instead of crustaceans.
00:17:13The fish mixture is then heated and pressed into shape.
00:17:17The logo for Beats is just a lowercase b inside of a red circle.
00:17:22The circle represents a human head, with the b being the headphones in their shape.
00:17:28All those little black dots around the edges of car windows are called frits.
00:17:32A frit is a painted black enamel that's put into windshields during manufacturing.
00:17:37They block ultraviolet rays and help distribute temperatures between the metal and glass.
00:17:43There are 24 symbols hidden inside the Unilever logo.
00:17:47Let's count, shall we?
00:17:49The sun, dove, plant, spark, chili pepper, spoon, bowl, flower, ice cream, hand, hair,
00:17:58Lips, swirl, fish, clothes, bee, particles, packaging, transformation, waves, DNA, palm
00:18:08trees, heart, and virtuous cycle, whatever that is.
00:18:12These represent everything that the company believes in and produces.
00:18:16DNA?
00:18:17Bobby pins are designed so that the zigzag part goes onto your scalp, not the flat part.
00:18:23It gives a greater grip on the hair and skin, making the pins stay in longer.
00:18:28The story that the pins were named after those fashionable London constables called
00:18:33Bobbies is not true.
00:18:35I made it up.
00:18:38Have you ever been vibing out in your room, listening to some of your favorite songs,
00:18:42admiring the subwoofer of your speaker as it delivers magnificence to your eardrums?
00:18:48We all have!
00:18:49But have you ever asked yourself why that same speaker, along with other speakers across
00:18:54the globe, is almost always black?
00:18:57Some of you are probably screaming at your screen right now about your speaker being
00:19:00green, red, or any other color found in the rainbow.
00:19:04Number one, I said almost always.
00:19:07And number two, if you look closely at the gorgeous design of your brightly colored music
00:19:11player, you'll often find that the speaker beneath it is still colored black.
00:19:17One possible explanation for this is that the original technology of speakers had a
00:19:21diaphragm with black particles on it.
00:19:24So as soon as a sound is amplified, it sends a charge through the diaphragm, and these
00:19:29black particles are driven upwards.
00:19:31The carbon particles bouncing and touching the upper membrane of the diaphragm are responsible
00:19:36for creating some of the distinct sounds from our speakers that we all love so much.
00:19:42Speaker manufacturers must've gotten tired of their products changing color with prolonged
00:19:46use, combined with these black particles settling on the upper membrane of the diaphragm.
00:19:52So their logical solution was to color most speakers black.
00:19:57Another more practical belief as to why speakers are mostly colored black is that it's a hue
00:20:02that easily matches up with many types of decor.
00:20:06Walls, furniture, and clothes all often look quite well when combined with this color,
00:20:11which is why it's so prevalent everywhere you go.
00:20:15Listening to music has repeatedly scored in the top 10 pastimes in the U.S. based on research.
00:20:21Nowadays, you find sound speakers everywhere.
00:20:24In your television, laptop, and your phone, you can't escape them!
00:20:29But let's take a look at how they started off.
00:20:32Their origins are in radio and telephone technology.
00:20:35The first form of a speaker was developed by Johann Philipp Reis in 1861.
00:20:41The German was a self-taught inventor and installed the speaker on his telephone.
00:20:46It was just about able to reproduce clear tones, but it could also replicate muffled
00:20:51speech after a few revisions.
00:20:55Alexander Graham Bell, the inventor of the telephone, decided to try and produce an improved
00:21:01version of Reis' speaker.
00:21:03Essentially, Bell and other inventors wanted to make an electrodynamic speaker.
00:21:08By 1877, it was still yet to exist, but due to the desire of inventors worldwide to change
00:21:15Research confirmed that it was extremely possible to make one.
00:21:19In particular, the work of Wernher von Siemens, who came up with the idea of an electromagnetic
00:21:24coil-driven speaker, was a driving force in arriving at this conclusion.
00:21:30Why are there magnets in speakers, you might ask?
00:21:33Every speaker nowadays has an electric current, something the inventors were discussing would
00:21:38never have taken for granted at any point in their lives.
00:21:41When this electric current is changing, it produces a magnetic field.
00:21:46To make the panel of the speaker move, magnets are used to create an opposing magnetic field
00:21:51which creates vibrations.
00:21:53These vibrations are the sound we end up hearing.
00:21:56The bigger the magnet, the louder the speaker will be.
00:22:00Another inventor by the name of Thomas Edison from the US had filed a British patent for
00:22:05a system using compressed air for an amplifying mechanism.
00:22:10The first commercial electric loudspeaker saw the light of day only in 1924.
00:22:16The sound quality produced by this speaker was good enough for motion pictures.
00:22:20It took nearly 20 years for the next groundbreaking development in the world of loudspeakers.
00:22:26This came with the arrival of the duplex driver in 1943.
00:22:30It offered better clarity and coherence at high volumes, which was important in movie
00:22:35theaters.
00:22:36Fittingly, it was nicknamed the Voice of the Theater.
00:22:39The duplex driver was immediately tested by the Academy of Motion Picture Arts and
00:22:44Sciences and instantly made its film house industry standard in 1955.
00:22:50Until now, this loudspeaker design is still used.
00:22:54Indeed, the film industry does seem to put a lot of effort into its sound, and so did
00:22:59the theaters we watch them in.
00:23:01You may have noticed that these buildings often have thick curtains on the walls.
00:23:05These are soundproof or acoustic curtains, and both are much thicker than regular curtains.
00:23:11They will either consist of heavier fabrics that are tightly woven or have better quality
00:23:16linings.
00:23:17This means that these curtains will absorb sound and reduce the acoustic reflection off
00:23:21the ceiling, windows, and flat walls of the room.
00:23:25This ultimately creates a much better sonic experience.
00:23:28The carpet floors are so thick in theaters for the same reason.
00:23:32It helps to trap sound by providing insulation.
00:23:35From a practical standpoint, this carpet is also set up to prevent the sound of footsteps
00:23:40during film screenings.
00:23:42This concept of trapping sound is also the reason why putting a phone inside a cup will
00:23:47make the phone's speaker seem louder.
00:23:50Any speaker sitting or suspended in an open space projects its sound in all directions.
00:23:56As the speaker vibrates to create sound waves, an equal amount of energy leaves from both
00:24:01the front and the back.
00:24:03By placing a speaker in some form of enclosure, we can redirect some of the energy that comes
00:24:09from the back of the speaker and project it forwards.
00:24:12By putting the speaker in a cup, you're directing the sound more efficiently.
00:24:16It travels only one way, making it seem louder than what you'd hear when you take it out
00:24:21of the cup.
00:24:23Speaking of phones and speakers, ever wonder why your mobile device makes your speaker
00:24:28produce a buzzing noise?
00:24:30This can occur when the two gadgets are near one another and your mobile is trying to send
00:24:34and receive data.
00:24:36The transfer of information produces electromagnetic disturbances in the medium around the speakers.
00:24:42It creates noise in the audio, and as a result, you can hear the buzzing sound coming from
00:24:47the speaker.
00:24:48A simple way to protect the amazing vibe your speaker is creating for you from this irritating
00:24:53buzzing noise is just to move your phone away from your speaker, or vice versa.
00:25:00This will eliminate what is officially known as electromagnetic interference.
00:25:06Research across America shows that, on average, 74% of people own two or more pairs of headphones.
00:25:1346% of them mention they listen to their headphones for more than 2 hours per day.
00:25:19Some choose the headphones by their looks, others by the sound quality.
00:25:23In either case, finding the right pair is important since a lot of people are willing
00:25:27to spend over $100 on it.
00:25:30Headphones have become a true fashion accessory.
00:25:34That's why well-known figures are trying to make an impact in the headphone industry like
00:25:38it's the fashion industry.
00:25:40Music moguls Dr. Dre and Jimmy Iovine came up with the idea for the now world-famous
00:25:45Beats by Dre Headphones brand.
00:25:48They were walking along the Pacific Ocean one day in 2006 discussing a sneaker deal
00:25:54as they had an offer on the table from a major brand in that arena.
00:25:58After some discussions, they decided they wanted to do something they were more passionate
00:26:02about and landed on headphones.
00:26:05The duo's idea turned into a brand that was purchased by Apple in 2014 for $3 billion.
00:26:12It was the largest deal in Apple's history, and Beats by Dre controlled 70% of the headphone
00:26:18market at the time of signing.
00:26:20The move allowed Apple to take over the headphone space.
00:26:23The release of their popular wireless AirPods headphones in 2016 was another reason it happened.
00:26:30But how do these popular wireless headphones that many of us own actually work?
00:26:35These headphones rely on internal batteries to have enough power to remain wireless.
00:26:41Most often, they have conveniently built-in rechargeable batteries, but sometimes they
00:26:46keep going thanks to standard AA or AAA batteries.
00:26:50They receive wirelessly transmitted signals from their paired audio sources, be it your
00:26:55phone or laptop.
00:26:57These signals are encoded by the source device and transmitted most commonly via radio frequencies
00:27:03or infrared carriers.
00:27:05The headphones receive the signal and decode it to audio.
00:27:09And just like that, it's music to your ears.
00:27:12So, you hungry, but not quite ready to eat a three-course meal just yet?
00:27:20How about some instant noodles instead?
00:27:23Ah, the water's boiled, your tummy's rumbling, but there's a problem.
00:27:27The Styrofoam cup's broken, and the noodles are exposed.
00:27:31Wait, is that a space at the bottom of the cup?
00:27:34Why?
00:27:35That space is for protecting the noodles.
00:27:37It's not the company trying to save money or anything.
00:27:40Notice how the ramen in cups is hardly ever broken, but the one in the packet comes out
00:27:45looking like a mess?
00:27:47This technique is called a middle suspension.
00:27:49The noodles are packed in tightly to stop them from getting crushed in the delivery
00:27:53truck.
00:27:54It's not just about the noodles looking nice and long.
00:27:57It also helps those tasty noodles soften more easily.
00:28:01Now, morning breath isn't the best.
00:28:03Luckily, there's an easy way to get rid of it.
00:28:06Yeah, it would've been easy to think that mouthwash was invented for, you know, washing
00:28:11your mouth.
00:28:12Well, mouthwash was originally invented and sold as a floor cleaner.
00:28:17It was sold to hospitals as an antiseptic for years.
00:28:20It never really took off.
00:28:22Some genius in marketing rebranded it as a mouthwash, and the rest is minty fresh history.
00:28:28So, after you've cleaned your teeth, just remember, rebranding can be pretty powerful.
00:28:35It's hard to imagine a world without the Internet these days.
00:28:38No streaming, no online games, or pictures of cute little kitties.
00:28:42Yeah, that's not what it was designed for, but who cares, right?
00:28:46The prototype Internet was called ARPANET, or the Advanced Research Projects Agency Network.
00:28:53This machine was very sensitive.
00:28:55To stop anyone from turning it off, some clever scientist stuck a piece of paper on it with
00:28:59these powerful words.
00:29:01This machine is a server.
00:29:03Do not power it down.
00:29:04It was written in red ink.
00:29:06Hey, nice touch!
00:29:09Having your professor scribbling in the margins of your notebook isn't exactly new.
00:29:13Except that margins weren't designed for that.
00:29:16They're rat protection.
00:29:18Back in the day, rats would nibble on paper all the time.
00:29:21So, if you wrote something on the edge of the paper, it ended up inside a hungry rat.
00:29:26A couple of well-placed lines stopped your best answers from getting eaten.
00:29:31Hey, I can't finish this pizza.
00:29:34Time to cover up those leftovers.
00:29:36Luckily, I have plenty of plastic wrap.
00:29:39A little tug, and the roll just jumped out.
00:29:42Prison break!
00:29:43If you look at the rat's home – the long, thin box – there's a special little feature
00:29:48that can help you.
00:29:49A cardboard tab on each end.
00:29:52Push them in, and the roll's not going anywhere.
00:29:55Strange that I've never seen them before.
00:29:59It's lunchtime.
00:30:00I'm feeling like a California roll today.
00:30:03Seaweed, rice, cucumber, avocado, and crabmeat.
00:30:07Or is it?
00:30:08It's actually imitation crabmeat.
00:30:10It's basically cheap white fish blended with sugar.
00:30:14The fish mixture is then heated and pressed into shape.
00:30:18Yummy!
00:30:19That's maybe why it's called the hot dog of the sea.
00:30:22Nah, I just made that up.
00:30:25Your microwave has a secret we've all seen, but never paid attention to.
00:30:30That black mesh you see on the door is a Faraday cage.
00:30:34It stops the electromagnetic energy, or the microwaves, from escaping – and cooking
00:30:39you too.
00:30:40That's how it heats up your food so quickly.
00:30:43Every microwave has to have one, and they all vary in quality.
00:30:47This Faraday cage can even stop signals from your phone.
00:30:51Which I guess is useful – you don't need your popcorn to stop popping in order to take
00:30:55a call, do you?
00:30:56Airplane mode's a bit easier, though.
00:31:00Ever taken an IQ test and realized you're Einstein-level smart?
00:31:04Me neither!
00:31:06The median IQ is only 100, plus there's very little evidence that Einstein ever even
00:31:12took the test.
00:31:13In the beginning, most people thought the test was too vague to be helpful in any way.
00:31:18The test was designed for children who needed help with their studies.
00:31:21Later, they realized it could be adapted to identify intelligence.
00:31:26But it was never originally designed for that.
00:31:29Hey, never pop bubble wrap!
00:31:31You're missing out!
00:31:33And you guessed it – it was never meant to be popped or used in the way we use it
00:31:37today.
00:31:38It was invented as a new, textured wallpaper.
00:31:42By sealing two shower curtains together, they created the first bubbles.
00:31:46The idea never really took off, obviously.
00:31:49After failing as wallpaper, it discovered its true meaning in life – it could protect
00:31:54sensitive items.
00:31:56When the first computers were being shipped, bubble wrap was there to help.
00:32:00Imagine a house with bubble wrap wallpaper in every room.
00:32:03Best or worst thing ever?
00:32:05Leave me a comment below!
00:32:08If you owned one of the biggest companies in the world, selling one of the most known
00:32:12products on the planet, how would you keep your company's secret a secret?
00:32:17The formula for Coca-Cola isn't patented.
00:32:20The first recipe was, but when they made changes, no patent ever went through.
00:32:26The secret formula is still only known by a few people at the company.
00:32:30Not only that, but not even Coca-Cola's rival wants the recipe.
00:32:35In 2006, a disgruntled employee tried to sell off the secret, but it didn't work.
00:32:42Hey, take a look at your brand-new mattress.
00:32:45Do you see the Do Not Remove Under Penalty of Law tag?
00:32:48Wow, that thing looks pretty serious.
00:32:51Good news, though – the tags aren't meant for you.
00:32:54They're aimed at the mattress seller.
00:32:55100 years ago, mattress makers used to create the filling with basically anything.
00:33:01Animal hair, old hospital beds, or clothing.
00:33:05Then strict laws stopped old hospital beds from being used.
00:33:09Their mattresses were filled with germs.
00:33:12On a rainy day, Play-Doh is something everyone can make at home.
00:33:16Mash up some flour, water, salt, food coloring, and wham!
00:33:21Any creative person is amused for hours.
00:33:24Cheap, clean, non-toxic – the perfect modeling play.
00:33:28But it was never made for that.
00:33:30This stuff was originally for cleaning up walls in the 1930s.
00:33:34That's because people started going crazy for wallpaper, which you couldn't use soap
00:33:38and water on.
00:33:39Eventually, Play-Doh had to find a new home.
00:33:44Have you ever finished a lollipop and noticed a hole in the stick?
00:33:48This hole isn't just for show or to make a musical instrument with after you're
00:33:52done.
00:33:53It's there to keep that tasty sweet treat from falling off.
00:33:57While the candy's still hot, it's poured into a mold.
00:34:00As it hardens, the candy flows into the hole and creates an anchor.
00:34:06Not into lollipops?
00:34:07How about good old American gummy bears?
00:34:10Unfortunately, they aren't American at all – they're German!
00:34:14A German company started making them in 1922.
00:34:17The original name was Gummy… something something.
00:34:21Anyway, they got the inspiration from real dancing bears at live shows.
00:34:26These treats eventually made it all the way around the world.
00:34:30Ever wondered what those little bumps were for on the F and J keys on your keyboard?
00:34:35These little raised ridges are to help your index fingers be in the best possible spot
00:34:41for lightning-fast typing.
00:34:43If you can keep those fingers on F and J, it makes it way easier to reach all the keys,
00:34:47especially if you don't look at the keyboard.
00:34:50Now, everybody loves a Slinky.
00:34:52If you've ever watched one of them strut down the stairs with groovy music in the background,
00:34:57congrats – you're definitely a YouTube fan!
00:35:01People of all ages loved it when it came out.
00:35:03Which is crazy because it was never meant to be a toy at all – it's a spring!
00:35:09It was originally designed to stabilize sensitive nautical devices on ships.
00:35:14Nothing fun about that at all.
00:35:16Until that amazing day when one of them fell off a table and danced its way into our hearts.
00:35:22After many experiments, the new and improved Slinky was born.
00:35:26Give that team of scientists a medal!
00:35:30Now that little pocket on your jeans wasn't designed for loose change or keys.
00:35:34It was originally made to store your pocket watch.
00:35:37You don't have a pocket watch?
00:35:39How is that possible?
00:35:41They were all the rage in the 1890s!
00:35:44But that's not all that makes your old pair of jeans interesting.
00:35:48Look around the pocket areas – you'll see rivets sticking out.
00:35:51No, they're not some cool fashion idea from the past.
00:35:55These rivets serve a very crucial role – they help protect the sensitive areas of the jeans
00:36:00that get the most wear and tear.
00:36:03Back in the day, most people wore jeans to do hard manual labor, so they needed to be
00:36:07tough.
00:36:08If those guys back then saw you paying $100 for a pair of ripped jeans, they'd probably
00:36:13pass out from shock.
00:36:15Seatbelt on the passenger seats has a fabric loop.
00:36:19When put under a great amount of pressure, the stitches on the loop rip apart, so the
00:36:23excess fabric can assist in cushioning the passengers.
00:36:27The extra few inches can make a great difference within a dire circumstance.
00:36:31However, there isn't one on the driver's side.
00:36:34As the driver is so close to the steering wheel, it's safer for them not to have one.
00:36:40Seatbelts were originally invented in the mid-19th century, though this technology wasn't
00:36:45brought into common practice until the 1960s.
00:36:49Pre-collision sensory technology has assisted with developing the safety of seatbelts and
00:36:53other features to the next level.
00:36:56Effectively predicting a car's collision, the technology directs the seatbelts to automatically
00:37:01tighten, aligning the airbags and ensuring the brakes will be pre-loaded to reduce shock.
00:37:08Every year, 6 million car accidents occur, which explains why all cars still must continue
00:37:13to develop safety features, not only to alleviate accidents, but to protect people more effectively
00:37:19within their cars.
00:37:22The materials that make up the body of cars only started getting replaced within the last
00:37:2625 years, ranging from aluminum and magnesium alloys to carbon fiber composites.
00:37:33These lighter materials not only enable a more fuel-efficient journey, but they also
00:37:37ensure that when a car is in an accident, its build provides a crumple zone.
00:37:42As a car hits another object, the crumple zone absorbs energy from the collision.
00:37:47Although this would appear to cause more damage to the car, it helps prevent impact on the
00:37:52passengers.
00:37:53Front and rear bumpers are very underrated, and due to their long history of being used
00:37:58in cars, you can't imagine a time we didn't use them.
00:38:02They were invented in the late 1800s.
00:38:05The bumpers evolved over the years to the point we don't even realize we have them.
00:38:09But they're there, quietly waiting under the outer covers, consisting of compressible foam
00:38:14or plastic around a rigid reinforced bar.
00:38:18All the windows of your car are made of glass, but the windshield is made of a shatterproof
00:38:24version.
00:38:25It's laminated, so whatever might hit it, you can be sure there won't be any shards
00:38:29of glass falling into the front seats.
00:38:32Normal glass was used up until the 1950s.
00:38:35As vehicles became more prominent, they made modifications to ensure safety.
00:38:41Airbags seem like another common feature that has always been there.
00:38:45In fact, they were originally invented in 1968 and were ahead of their time.
00:38:50They slowly gained popularity, and through safety precautions for cars, they eventually
00:38:55became mandatory for all cars to have, only in 1998.
00:39:00They have since developed from just being an airbag within the steering wheel.
00:39:04Today, depending on the vehicle, they can be located throughout the car, ensuring all
00:39:09potential passengers will be protected.
00:39:12Flash sensors connected to an onboard computer detect when a collision occurs and trigger
00:39:17the bags, inflating within milliseconds and providing a cushioned safety within a blink
00:39:22of an eye.
00:39:24It can be difficult to predict the weather, and even more so to determine traction on
00:39:28the road.
00:39:29In the late 1960s, anti-lock braking systems, ABS, were implemented in vehicles.
00:39:36Before that, they had been used in many aircraft, with designs going as far back as 1908.
00:39:42They soon became a necessity for all vehicles, ensuring traction is maintained on slippery
00:39:47surfaces and that there is complete control when braking.
00:39:51Today, ABS has advanced so much that the latest variations ensure further detection when there
00:39:57are strong crosswinds.
00:40:00Adaptive cruise control, initially invented in 1948, has been in constant development
00:40:05over many decades.
00:40:06Today, adaptive cruise control ensures that when the car is cruising at a constant speed
00:40:12and detects a slower car ahead, it will then adjust the speed to match the car in front.
00:40:17Other advanced variants may also ensure the car will make a complete stop once identifying
00:40:22that the car in front has done the same.
00:40:26It's easy to forget to have your high beams on when driving on the long and lonesome road
00:40:30for many hours.
00:40:31Automatic high beams are quickly becoming more common.
00:40:35High-tech camera modules can easily determine what type of light is passing through and
00:40:40help ensure when the high beam will be necessary.
00:40:43Although versions of automatic high beams have been around since the 1950s, they counted
00:40:48on light-sensitive sensors and were very unreliable.
00:40:52The new varieties can identify the sources of light, whether it's from the sun, directly
00:40:57from a car's light, or even from the reflection on a sign, ensuring you won't cause issues
00:41:02with other drivers.
00:41:05It's a pain in the neck to have to ensure there isn't anyone creeping into that semi-visible
00:41:09corner, the blind spot, which causes around 400,000 accidents per year.
00:41:15Solar sensors within rear bumpers of vehicles and blind spot monitoring systems watch and
00:41:20identify adjacent lanes.
00:41:23They alert the driver that a vehicle may be in the lane beside them, whether by flashing
00:41:27lights on the dash or from beeping sounds.
00:41:30This way, they help to alleviate the many concerns the blind spot causes.
00:41:351.6 million road accidents are caused by texting and driving, and fatigue normally causes up
00:41:42to 10% of all car accidents per year.
00:41:45The driver attention monitor helps to alleviate both statistics.
00:41:50It works through sensors that monitor the car's movements and the amount of steering
00:41:54corrections to ensure the driver is paying attention to the road.
00:41:58When the system identifies that the driver isn't completely awake or is slightly distracted
00:42:02with their phone, it will prompt signals to suggest it's time for a break.
00:42:08Tires are among the most critical components for your car, with a close relationship with
00:42:12whatever path you take.
00:42:14Many safety features rely on the tires themselves for their own independent purposes.
00:42:19That's why it's super important to ensure the tires are always in top condition.
00:42:23Tire pressure monitoring systems check the air pressure of all four tires, ensuring you're
00:42:28aware when they need their pressure increased to avoid the risk of a blowout.
00:42:33The constant evolution in technologies continues to ensure you stay safe on longer stretches
00:42:38of the road.
00:42:40Lane departure warnings focus on the lines on the road, ensuring the car stays within.
00:42:45Whenever a car starts drifting over a line in the road without signaling to do so, the
00:42:49camera-based feature identifies and signals to the driver.
00:42:54The lane-keeping assist feature follows the same method of identifying when the car is
00:42:58intruding the bordering lane.
00:43:00When it gets too close, it will readjust the steering and center the car within its appropriate
00:43:05lane.
00:43:07Other features in more advanced cars have autonomous driving capabilities.
00:43:12The Autopilot systems have taken cruise control to the next level.
00:43:16Not only does it allow the vehicle to steer itself in the intended lane while maintaining
00:43:20a set speed, but it also changes lanes when required, making the ride more and more efficient.
00:43:27Some safety features are only just making a trend in car models worldwide.
00:43:31For example, night vision, using thermographic cameras to look out for pedestrians and animals
00:43:37nearby.
00:43:38It goes within the infotainment screen, facing frontwards and identifying objects from their
00:43:43heat signatures.
00:43:45It's estimated that there are over 1.4 billion cars in use worldwide, and as the world's
00:43:50population increases, it's expected that the number of cars will follow suit.
00:43:56Safety features will continue to adapt further beyond what we know of today.
00:44:01Infrared headlights will be further adapted to be used in conditions with poor visibility,
00:44:05like storms, snow, and fog.
00:44:08They'll be capable of enhancing the visibility of the driver in all conditions without affecting
00:44:13the sight of passing drivers.
00:44:15Driver override systems will soon be able to monitor and identify human behavior.
00:44:20Whether due to reckless conduct on the road or for other safety precautions, cars will
00:44:25soon have the functionality to take complete control of themselves, ensuring both the passenger's
00:44:30and the driver's safety.
00:44:32Augmented reality windshields are in early development already, providing some indicator
00:44:37reflections from the dash onto the windshield.
00:44:40So it's quite possible that soon all necessary directions for maps and alerts will appear
00:44:45right in front of the driver to ensure they never take their eyes off the road.
00:44:51Airbags will soon not only just be used within a car to ensure the passenger's safety, they
00:44:56will also activate from the outside of the car once they identify a definitive collision.
00:45:01The airbags will inflate outwards, covering the entire outside of the car and drastically
00:45:06reducing its impact.
00:45:08It may be so advanced that the bodywork of the car won't even need to be buffed out.
00:45:13The future technology of cars is expected to be so progressive that the cars themselves
00:45:18will have their own form of communication, not with human drivers, but with other cars.
00:45:24Just imagine, cars communicating and sharing information as they identify roadblocks, issues
00:45:29on the road, or disruptive weather patterns.
00:45:32It will all ensure the most efficient and safest route possible.
00:45:36Okay, I know it's kind of cold to the touch, especially on a freezing winter's day.
00:45:44But did you know that brass doorknobs actually serve a purpose apart from looking classy
00:45:48and shiny?
00:45:49Since it's a copper alloy, brass has antimicrobial properties.
00:45:53That means it can help get rid of harmful germs and bacteria, sometimes in up to two
00:45:58hours.
00:45:59In high-traffic areas, that's all the more useful.
00:46:02But since brass is much costlier than other metals like nickel and steel, you barely see
00:46:07these types of doorknobs anymore nowadays.
00:46:10Speaking of lovely multi-purpose items, most screwdrivers have a tiny little secret of
00:46:14their own.
00:46:15They can sometimes be slid through a wrench so that they can be used to create more torque
00:46:19when twisting, not to mention the uses when it comes to bolts in hard-to-reach places.
00:46:25There's a reason why buttons on women's shirts are for the left-handed, and it has nothing
00:46:30to do with fashion.
00:46:31This practice dates back to the times when chambermaids were helping ladies dress themselves,
00:46:36and it was easier for them to perform their job with this orientation.
00:46:40Having the buttons placed as such indicated a sign of wealth, so it's easy to imagine
00:46:45why the practice carried on, even though most people dress themselves nowadays.
00:46:50Next time you receive a package in your mail, take a look at your box cutter.
00:46:55If it features some diagonal lines on the blade, you're in for a little design perk.
00:46:59Turns out that these are blades that snap off.
00:47:02Continuously cutting cardboard can dull the sharp edge of the blade.
00:47:06To help prevent the need to buy a brand new box cutter, the top segment along the next
00:47:10line can be broken off to reach a new sharp edge.
00:47:14To do this, check out the small hole at the base of the tool, sometimes called the blade
00:47:18snapper.
00:47:20The people that first came up with this brilliant invention were engineers inspired by the way
00:47:24chocolate bars are segmented.
00:47:26Hold on a minute, don't throw away the cardboard package just yet.
00:47:30Most likely, you'll have some silica gel packets somewhere at the bottom of the box.
00:47:34Since this gel is basically a drying tool, it gathers up the moisture out of its environment,
00:47:39so you can store these packets for further occasions.
00:47:42Whether you'll need to dry out your phone or some other electrical object, you can place
00:47:46them in a container next to the silica gel to reduce the damage.
00:47:50You don't have to be a mechanic to know when a standard car tire needs replacing, since
00:47:54they come equipped with a neat indicator.
00:47:57Take a closer look, and you'll see that treads within the tire are a bunch of rubber notches.
00:48:03When the treads are evened out with the perpendicular bars, it's a sign you need to book an appointment
00:48:08with your local car service, since most likely the tires have lost most of their traction
00:48:13and may not be safe for driving any longer.
00:48:16The upper corners of a car windshield feature textured black dots melted into the glass edges.
00:48:22This neat add-on isn't there for design purposes.
00:48:25It's called Frit Glazing, which means that a special type of ceramic paint is added to
00:48:31the window for protecting its sealant from UV rays.
00:48:34It also conceals and creates a coarser surface for the adhesive used to set the window in place.
00:48:41Whenever you're up for a drive, check out if there's a small tab under your car's rear-view mirror.
00:48:47Bet you didn't know it's there to help switch the mirror from daytime to nighttime views.
00:48:53It uses a prismatic glass technology to blur the reflection and reduce the glare of headlights
00:48:58behind you in traffic.
00:49:01People came up with these manually tilted mirrors in the 1930s, but they became standard
00:49:05somewhere in the 1970s.
00:49:08While you're in the car, check out the headrests, as you most likely don't know that they carry
00:49:12a little disguised purpose.
00:49:15Of course, they're adjustable to accommodate passengers of any height so that they get
00:49:19the proper support for their heads and necks.
00:49:21The hidden feature is that they are detachable and come with two very solid metal bars.
00:49:27Should you ever find yourself stuck in a car and need to make a fast getaway, these bars
00:49:32come in handy to crack out the car windows.
00:49:35So you're out for a drive and you're suddenly out of gas.
00:49:39What I'm about to describe sounds more like a meme than an actual situation bound to happen.
00:49:44But what if you're in such a hurry that you accidentally drive off with the gas nozzle
00:49:48still in the tank?
00:49:49Well, the nozzles have been designed to prevent any hazards from happening, rest assured.
00:49:55They feature a breakaway device that will allow the hose to separate when taken out
00:49:59with enough force.
00:50:01Initially designed in the early 20th century to be worn exclusively by basketball players,
00:50:07sneakers soon became one of those fashion fundamentals similar to jeans and leather
00:50:11jackets.
00:50:12If you take a closer look at them, you'll see they have two extra holes on the side,
00:50:16similar to the shoelace holes.
00:50:18They're manufactured as such not only to provide extra ventilation but to allow people to get
00:50:23extra creative with their laces when wearing the shoes.
00:50:26Admit it, you've always thought that chopsticks are merged at the end for the sole purpose
00:50:30of keeping them together until you're ready to dig into your meal.
00:50:34That may or may not be the whole truth.
00:50:37Under a more detailed inspection, the wooden tools feature a square-shaped end.
00:50:42Chopsticks manufactured like this date back to an old Japanese traditional design, which
00:50:46can help with breaking the ends easily.
00:50:49The separated end can then be used as a resting block for the chopsticks to keep it more sanitized
00:50:55in hopes it can be used again, since they won't be touching the table or any other
00:50:59surface.
00:51:00Women's bikes have a special design which, surprisingly, has a historical and fashionable
00:51:06purpose.
00:51:07The lower frame is for the most part meant to make up for the generally shorter height
00:51:11of ladies, compared to that of the average gentleman.
00:51:14While that is the case for handlebars and saddles, the overall frame is lower for an
00:51:19additional purpose.
00:51:20Way back when women wore long skirts and dresses all day, every day they needed to make sure
00:51:25their outfits wouldn't get caught in the frame.
00:51:28That's how we came up with a lower-framed bicycle, perfectly made for women and their
00:51:32needs at the time.
00:51:35The fact that toothpastes are multi-colored is not just a nice perk to make dental hygiene
00:51:40more fun.
00:51:41There's a secret meaning related to each of the colors, which dates back to the 1970s.
00:51:46In those days, people grew more and more interested in their oral health care, and
00:51:51as such, they were looking for products which could do more than merely clean their teeth.
00:51:56One company was the pioneer in that regard, adding mouthwash to its toothpaste, meaning
00:52:01the blue strip.
00:52:02They later added on the red strip, meant to feature ingredients which helped with gum
00:52:07care.
00:52:08Speaking of toothpaste, check the cap next time you open a new tube, you may be in for
00:52:13a little surprise.
00:52:14There's a pointed cone shape inside the cap so you can puncture the seal of the toothpaste
00:52:19without cutting yourself or ruining your manicure.
00:52:22Not to mention it's more hygienic since you won't be able to transfer germs or other
00:52:26bacteria into the product itself.
00:52:29On the subject of bathroom countertop items, toothbrushes come with a neat add-on hidden
00:52:34in the bristle patterns.
00:52:36Apart from making the toothbrush look cooler, they also do come with a practical purpose.
00:52:41Most toothbrushes come with a pattern of blue bristles intertwined with white ones.
00:52:46The blue dye is meant to fade out, signaling the time when you need to replace your toothbrush.
00:52:52Dentists say that toothbrushes should be replaced every three to four months, but it does serve
00:52:56as a great reminder in case you forget.
00:52:59Still love playing with Lego?
00:53:01Don't judge, hey, it's a great hobby for all ages.
00:53:04Notice there's a hole on top of the Lego heads?
00:53:07Behold, you're looking at a safety feature that the people at Lego designed to prevent
00:53:12choking hazards.
00:53:13The most dangerous issue should a person swallow any of these pieces is the blocking of the
00:53:18airways.
00:53:19Designing a hole inside the Lego head helps the air to flow freely through the piece until
00:53:24it can be removed safely.
00:53:27We're now used to all sorts of modern light bulbs, some tubular, some shaped like diamonds,
00:53:32and some even twisted all together.
00:53:35Historically, light bulbs were round and the initial shape served a purpose in itself.
00:53:40It was mainly connected to the fact that glass bulbs were hand-blown, which gave them the
00:53:44round shape to begin with.
00:53:46The hidden practical reason was that the light bulb filament needed to be at the same distance
00:53:51from every surface of the glass sphere.
00:53:53The easiest way to achieve this was to make the glass in the shape of a globe.
00:54:00The cylinder on the end of a cable is sitting there, useless as it might seem.
00:54:05In fact, this is a ferrite bead that assists with many electrical wires to reduce electromagnetic
00:54:12interference.
00:54:14Electrical wires act like unintentional antennas, broadcasting the EMI.
00:54:20There's a reason why the spinning wheel inside the microwave is circular.
00:54:24A circular object will evenly distribute the heat as opposed to a rectangular and square
00:54:29one.
00:54:31When you place containers of these shapes inside, the energy is focused on the corners
00:54:36rather than spread evenly like in a round container.
00:54:41The temperature gauge on a toaster is commonly used to determine how crisp you like your
00:54:45toast, but the other, more specific use for the gauge was for the different types of bread.
00:54:52White and sweet types of bread heat up much faster as opposed to heavier brown and rye
00:54:57ones.
00:54:58The older bread is, the more time it will need in the toaster to ensure the golden brown
00:55:03results you're looking for.
00:55:06Most ovens give you the option of leaving the door ajar when broiling a dish inside.
00:55:12You probably think the goal here is to help cool down the oven after use.
00:55:17In reality, its purpose is to focus on cooking the top of the dish and to ensure a crusty
00:55:22layer.
00:55:24Controlling the buildup of heat and steam by releasing it through the slightly ajar
00:55:28door gives you the desired result without cooking the entire dish to a crispy end.
00:55:35You probably noticed that your dishwasher has specific areas for different types of
00:55:40cutleries and dishware, but all the dishware pieces should be facing towards the center
00:55:45and not all in one direction.
00:55:48What types of foods were on the plates will also determine where they should be located
00:55:53in the racks.
00:55:55As the middle of the machine gets the strongest spray, carb-based stains from tomatoes and
00:56:00potatoes should be placed there.
00:56:02The detergent is more focused on the outside during the clean, creating a waterfall-like
00:56:07cleanse.
00:56:08That's why protein-based stains, like from eggs for example, should be stacked there.
00:56:16Ceiling fans push cool air down on a hot day, circulating the room, but they can serve you
00:56:22during the winter just as effectively if you flick that switch on the side or use the pulley.
00:56:28So if you want to save some money on heating and try to quickly warm up your room on a
00:56:32cold day, turn the fan on, it will push the air up and spread the warm air around, more
00:56:38effectively warming the room up.
00:56:40Do you still use sticky notes instead of those fancy new apps on all possible gadgets?
00:56:47Welcome to the club.
00:56:48Regardless of what you use them for, they can annoyingly curl up.
00:56:52If you've had this issue, it's because you've peeled them from the bottom upwards.
00:56:57Doing it this way causes the curling.
00:56:59Peeling them from the side will ensure they remain flat, ready to remind you of your daily
00:57:04tasks.
00:57:05Did you know that can openers weren't invented until 50 years after preservation cans had
00:57:11been readily available?
00:57:13So how would it be possible to open a can?
00:57:16Here are a couple of alternative methods just in case you've misplaced your trusty opener.
00:57:22All you need is a metal spoon.
00:57:24Set the can down on the counter, hold onto it firmly and grasp the head of the spoon
00:57:29tightly.
00:57:30Apply pressure and vigorously rub the edge of the can's top over a small area.
00:57:36It takes time, but as you continuously rub, a small indentation soon opens a hole.
00:57:42Once the hole is wide enough for the spoon's tip, pry the lid upwards and keep going along
00:57:46the edges until you can finally access the hard-earned meal within.
00:57:51Most toilets rely on water pressure and gravity to function, so a power outage will not affect
00:57:58them.
00:57:59But if yours does need electricity to function, you must be worried about using it when the
00:58:03power is out.
00:58:05The good news is the power is only used to fill the toilet and not to flush it.
00:58:10As the flushing mechanism will still work, open the toilet tank and pour in a couple
00:58:14of gallons, and you're free to flush away whatever you need to.
00:58:20Blockages in shower drains occur over a long period of time.
00:58:23It's inevitable.
00:58:24We lose 50 to 100 hairs a day, and many of them will endeavor to reside within our shower
00:58:30drains.
00:58:31Hair only forms the foundations of the blockage, and this attracts the build-up of various
00:58:36other things.
00:58:37A great life hack is to use your vacuum cleaner and put the nozzle in the hole once removing
00:58:41the plug.
00:58:43Apply a wet cloth around the nozzle, ensuring air cannot escape.
00:58:47The vacuum will suck up the blockages a lot easier.
00:58:51This will help avoid any extra costs from plumbers, as they themselves use this technique.
00:58:58To make your candles last longer, trim their wicks multiple times and keep them as far
00:59:02away from water and moist as possible.
00:59:05It will guarantee that your candle's wax stays firm and steady, and continues to burn
00:59:10slower for a longer period of time.
00:59:14The empty space between the panes of the oven door is there for a reason.
00:59:19You can stick a brush in there to clean the oven door glass.
00:59:22It's easy to access this space through the bottom of the door, open the lower shelf,
00:59:27then push the brush through the hole.
00:59:31While you're parking in a garage, you might find it difficult to determine how close to
00:59:34it you need to be.
00:59:37Not all cars have sensors ensuring you keep the right distance before the bumper makes
00:59:41an indentation on the wall.
00:59:43Applying a rope with a tennis ball from the ceiling at the right distance will help you
00:59:47learn the best distance to park from the wall.
00:59:51We've all been told to loosen a lock with WD-40 or lubricant.
00:59:55Yes, we all know we should have these around the house.
00:59:59But in case you don't, a great alternative is drawing with a grey lead pencil along the
01:00:03edges of the key and then putting it into the lock.
01:00:07Continue doing this until the keyhole has been adequately lubricated and the key functions
01:00:12smoothly.
01:00:14Pliers are prone to damage when you use them to adjust faucets and shower heads and are
01:00:19also difficult to grip.
01:00:21Take a couple of pieces from the end of an old garden hose and attach them to the jaws
01:00:25of the pliers.
01:00:27You'll find a huge improvement with grip and will avoid wear and tear.
01:00:33You can find a good use for discarded rubber for different things around the house.
01:00:38When fed up with tightening or loosening with a screwdriver, try using a simple rubber band.
01:00:44Place part of it into the screw grip and the screwdriver will have far greater traction.
01:00:50Moving cement blocks isn't safe for your lower back.
01:00:53Even with a wheelbarrow, it can be a risky process to place the cement onto the ground
01:00:58without causing damage.
01:01:00Three simple cylinder pipes can make a world of difference, regardless of the size of the
01:01:04block.
01:01:05Try lifting the edge onto the first pipe with a pry bar, then pushing and maneuvering as
01:01:11you gradually direct the three pipes towards the desired location.
01:01:15Just make sure you're not doing this on a slope.
01:01:19That first strike on a nail can be a great success or will result in a throbbing thumb.
01:01:25A bobby pin is perfectly shaped to hold a nail in place, allowing for your hand to be
01:01:30clear out of harm's way and for you to strike the nail without fear.
01:01:36Use a crayon instead of a pen or pencil while working with a wet saw to ensure the markings
01:01:41are not removed.
01:01:43They will also be easier to see under the murky water.
01:01:48Checking the drains on the roof and determining when they need to be cleaned can take a lot
01:01:53of time.
01:01:55Using duct tape, attach a mirror on the end of a long broom and review whether the drains
01:02:00need to be cleaned.
01:02:02To further assist with your balance as you check on the gutters, attach a pair of old
01:02:06trainers to the end of the ladder.
01:02:08The spread of the shoe and its grip will ensure a further level of safety.
01:02:14Liquid caulk normally comes in huge tubes, so you can never use it all at once.
01:02:19The hardened tips of liquid caulk create blockages.
01:02:23Grab a used cork and drill through it to make a perfect lid, concealing the liquid
01:02:27caulk.
01:02:28Now it's ready to be used again with no blockages!
01:02:33You know, there are all sorts of amazing things you can do with products already lying around
01:02:39the house that were meant for other things.
01:02:42We'll explore some of those, plus everyday items that have other purposes you may not
01:02:47be aware of.
01:02:49I'm also in a silly mood, so hey, let's have some fun!
01:02:53Many pairs of kitchen scissors today have a serrated opening where the handles and blades
01:02:58meet.
01:02:59You can use this as an herb stripper to de-stem difficult herbs like thyme, rosemary, and
01:03:05chives.
01:03:06Saves you a lot of time trying to pick the leaves off by hand.
01:03:10And if you're short of a vase, you could present roses to your significant other this
01:03:14way.
01:03:15Just be careful when you're pointing the sharp end.
01:03:19The metal tab on soda cans can be flipped around.
01:03:22You can slip a straw in place so you don't have to hold it up to your mouth.
01:03:26This stay-on tab replaced the pull-ring tab created in the early 60s.
01:03:31You remember those, don't you?
01:03:33Those could be quite sharp and easily discarded where they could be a menace for others.
01:03:38Now you can pop your straw straight into one.
01:03:42You means you can produce some bubbles and make a mess!
01:03:47Sometimes when you purchase an article of clothing, you receive a plastic baggie with
01:03:51an extra button and a swash of fabric.
01:03:54While the fabric is clearly used to patch holes, it can also be used to test the effects
01:03:59of various cleaners on certain surfaces.
01:04:02It's handy too to test wash cycles before using them to wash the whole garment.
01:04:08And if you want to clean your nose with it, that suggestion never came from me.
01:04:13You can use a screwdriver for leverage if you're having trouble lifting or moving
01:04:18something.
01:04:19Some also have a hexagonal-shaped handle that fits inside a wrench or spanner.
01:04:24You can use it to improve torque and, again, for leverage.
01:04:28A little easier on your hands.
01:04:30Some of us aren't that strong.
01:04:31Or maybe that's just me.
01:04:34Super bands are great for many things, but if you have a bottle that's hard to open,
01:04:39you can wrap the band around it for a better grip.
01:04:43Escalators have those fluffy black brushes for a similar reason that some have yellow
01:04:48lines on their steps.
01:04:50To try and deter people from getting too close to dangerous places.
01:04:54People don't always take notice, and sometimes clothing can drape close to a point where
01:04:59the step meets the edge or skirt.
01:05:02The brush is a little barrier to help prevent this from happening.
01:05:06They can also catch bits of fluff and prevent other small things from falling down into
01:05:11the gaps.
01:05:13Your average pair of jeans has several features that are both functional and somewhat sentimental.
01:05:19The metal rivets around the pockets help secure the stress points.
01:05:23This ensures they last a bit longer than average, though not all jeans have them.
01:05:29Many still have a tiny pocket directly above the main pocket.
01:05:34This was originally meant to hold a pocket watch.
01:05:37Even though pocket watches are mostly a thing of the past, many people still use this space
01:05:42to store coins, rings, or even a portable USB.
01:05:48This may seem a little obvious, but if you've ever wondered what all the notches are in
01:05:52a car tire, it's for traction on the road.
01:05:55However, there are also a good indicator if your tire is getting too worn down.
01:06:01If those notches aren't so deep anymore and are almost flush with the road, it's
01:06:06time to replace them.
01:06:08If you don't, the next time you try to stop suddenly at a stop sign, you might be surprised
01:06:13to find your car has turned into a giant roller skate.
01:06:18Those takeaway containers most associated with Chinese restaurants are designed to not
01:06:23only carry your food home, but to store them in the fridge.
01:06:27They double as a plate as you can eat straight out of them and don't have to worry about
01:06:32dirty dishes.
01:06:34They were actually patented way back in 1894 to transport freshly shucked oysters and were
01:06:41known as oyster pails.
01:06:43They were later adapted to use as leak-proof containers for food.
01:06:48While you're sitting on an airplane and looking out the window, you may have noticed
01:06:52those little holes, or in some instances, a small singular opening near the bottom.
01:06:58This is called a breather hole, and no, it's not for you.
01:07:01It's designed to equalize the difference in air pressure which builds up between the
01:07:06pressurized cabin and the atmosphere outside, especially during high altitudes.
01:07:12It also releases moisture from between the panes to avoid frost from forming on the windows
01:07:17and obstructing that all-important view.
01:07:20Sorry, but it looks like you won't be drawing a smiley face on it any time soon.
01:07:26This was first introduced way back in 1956 by a company in Japan.
01:07:31Pretty cool, huh?
01:07:33They got their inspiration from snap-off rows on chocolate bars.
01:07:37Just don't get the two mixed up.
01:07:39One doesn't taste good.
01:07:42When it comes to measuring tape, almost every reel has an empty slot in the metallic end.
01:07:47This is called a nail grab, so you can attach it to a nail or screw.
01:07:52A handy trick to do measurements without requiring someone else to hold it in place.
01:07:58Very nifty.
01:08:01Bobby pins have grooves on one side to hold your hair in place better.
01:08:05Crazy notion, huh?
01:08:07The straight side goes face up, while the grooves go down against your head.
01:08:12They're called bobby pins because of the bobbed hairstyle, which was popular in the
01:08:161920s, though the pins were invented in the 19th century.
01:08:21The look is gone, but the pins remain.
01:08:24Please take them out before you wash your hair, as they don't look great stuck to your
01:08:28fingers.
01:08:30If you've been in a car or a bus and noticed the textured black dots baked into the black
01:08:35edges, you've probably worked out that it's not there for its pretty looks.
01:08:40It's called frit, a ceramic paint.
01:08:43Its main purpose is to protect the window from ultraviolet rays.
01:08:47It also creates a rough surface for the adhesive to cling to.
01:08:51Now, if you see a pink lump of adhesive in the corner, please do not touch it.
01:08:57It's actually someone's old bubble gum.
01:09:01If you take a look at the bottom of the lock, chances are you'll see one or two little holes.
01:09:07This is to let water out from the inside that may have been trapped due to rain.
01:09:12This mini-draining capability prevents the inner working from rusting over or freezing
01:09:17in place if the weather's very cold.
01:09:20If in another situation the lock becomes stuck, you can ease an oil-based product inside to
01:09:27lubricate the lock and get it working again.
01:09:31If you've lost the key and want to ease your frustrations, you can yell into the holes.
01:09:36It won't do anything to unlock it, but it may help you feel a little better.
01:09:42Some dress shirts have a fabric loop on the back.
01:09:45You guessed it, it's used for hanging the shirt up.
01:09:48The loops were reportedly first used in the Navy, as it was easy to simply hang them on
01:09:53the wall.
01:09:55During the 1960s in colleges, the fashion of the day was to wear the shirt buttoned
01:10:00all the way to the top, which made them difficult to hang.
01:10:04So designers began putting the loop on the back.
01:10:07If the student removed the loop, it signified that they were going steady in a relationship.
01:10:12Unless your friend ripped one off for a prank, now everyone's asking whom you're with.
01:10:18There's a little more to this story, but we haven't got time to hang around.
01:10:24And yes, that's a bad pun.
01:10:26On purpose.
01:10:27It's what I do.
01:10:29Ever wondered why coins have those little ridges along the edge?
01:10:33It's a leftover from earlier times when they were worth more.
01:10:37Counterfeiters could easily file the edges off to sell as gold or silver coins to make
01:10:42some profit.
01:10:43The ridges were created so it was much easier to tell which of the coins had been altered.
01:10:49It's not needed today, but the coins still have that altered style.
01:10:53If you ever get really bored, you could try counting how many ridges there are.
01:10:58Actually, that is a very boring idea.
01:11:01Forget that and watch another Bright Side video instead!
01:11:07You just spent the entire morning running errands up and down the street, and you finally
01:11:11stopped to treat yourself to a cup of coffee.
01:11:14You enter the nearest coffee shop, place your order, and notice that actually, you really
01:11:19need to use the bathroom.
01:11:21It's a regular-looking public one with multiple stalls.
01:11:25As you pick yours, the one in the middle, you get inside, and your mind starts to wander.
01:11:30Why on Earth do bathroom doors have a half-inch gap between the door and the lock, and why
01:11:35on Earth do they have a huge gap between the door and the floor?
01:11:39Can we have a drumroll for this moment, please?
01:11:42Well, my friend, there is not only one specific reason why public bathroom doors have so many
01:11:47gaps in them, but rather several.
01:11:50Public toilets are designed to make people spend as little time there as possible.
01:11:55You aren't supposed to feel comfortable or at home.
01:11:58So the design would have to reflect this notion.
01:12:00Here come the gaps.
01:12:02In some bathrooms, gaps are so big that users may even feel self-conscious about doing their
01:12:08business out of preoccupation that the rest of the people standing in line will see them.
01:12:14Then there's the matter of pricing.
01:12:16Making custom doors can be a heavy burden for the people building public toilets.
01:12:20This would mean understanding exact measurements so that doors would always fit the mold of
01:12:25the stalls it's supposed to be installed into.
01:12:28Not all the gaps in public bathrooms are necessarily the same size.
01:12:33They may vary, even if this variation is small and often unnoticeable.
01:12:38So these gaps actually help to reduce the margins of errors and to turn production more
01:12:43cost-effective for the people financing them.
01:12:46In case a door comes wider or more narrow than it should, the gap regulates the differences
01:12:51and allows for their installation anyway.
01:12:54There is also the case of air circulation.
01:12:57The last thing you want to do in a public bathroom is to trap odors.
01:13:01So you need a little space under and between the doors to allow the air to flow.
01:13:06Finally, the gaps are a big safety measure.
01:13:09It can always allow for people on the outside to see if someone inside a stall isn't feeling
01:13:14too okay and maybe needs some help.
01:13:17And what about that extra hole in the upper part of the sink?
01:13:21It has a name in everything – the overflow hole.
01:13:24And it's designed to keep the sink from flooding.
01:13:27So in case someone forgets and keeps the faucet going for too long, or the sink gets clogged
01:13:32and water can't drain down from the main drain hole, the overflow hole comes in to
01:13:37save the day.
01:13:38Let's say it buys you a little time before you have the entire bathroom floor flooded.
01:13:43Have you ever noticed how satisfying closing the door of a car can be?
01:13:48Car manufacturers devote a great deal of time to designing these sounds.
01:13:52Studies have shown that they create a perceived sense of quality in the buyer.
01:13:56It all begins with the primary material.
01:13:59While older cars used to be made with heavier materials, car doors nowadays are produced
01:14:04with lighter tin, which can make a rather unpleasant metallic sound once you shut them
01:14:09closed.
01:14:10So car companies employ sound engineers to ensure that there is the exact amount of foam,
01:14:15mats, and tin in a car's composition to make the most comforting sound possible.
01:14:21And what about those tiny dots on the top of your car's front window?
01:14:25The pattern of these little black dots minimizes distractions for your eyes.
01:14:29This black part, also known as frit, normally gets warmer than the clear parts, which prevents
01:14:35the windshield from deforming.
01:14:37And no, the tab under your rear-view mirror is not made only for the purpose of hanging
01:14:42fluffy dice or aromatic-pleasing air fresheners.
01:14:45It's actually a switch that allows you to adjust the position of the mirror depending
01:14:49on the time of day.
01:14:51Flip it one way, and it's the daytime driving mode.
01:14:54Flip the other, and you're ready to drive safely during nighttime as it tones down the
01:14:58glare coming from headlights of the cars behind you.
01:15:02Next time you head out to the supermarket, make sure to keep this in mind.
01:15:06In case you don't have a coin to unlock these shopping carts, there is a well-kept
01:15:10secret that can help you out.
01:15:12If you have your house keys on you, check for a rounded keyhead.
01:15:16If you happen to find one, try using it to unlock the cart.
01:15:20It should fit perfectly in there, replacing the need to carry coins around.
01:15:24Because if we're being honest, who still has them?
01:15:27Elevators.
01:15:28If you want to ride them on your terms, and your terms only, make sure to try something
01:15:32out.
01:15:33Most elevators have a secret button combination you can use to skip all the other selected
01:15:38floors and go directly to the one of your choosing.
01:15:41This might work out, especially on those days when you've pressed 13, but you wanted
01:15:46to press 33.
01:15:48On most elevators, this works once you simultaneously press the close door button together with
01:15:53your floor number.
01:15:54This should help you get to your floor without stopping.
01:15:58Some elevators require you to double-press the selected floor numbers, as double-pressing
01:16:02will often cancel the previously made request, while other elevators require you to hold
01:16:08the open door button and then double-press the buttons of the floors you'd like to cancel.
01:16:13Now to stay out of trouble, it's best not to cancel the floors of the other people in
01:16:17the elevator.
01:16:18They won't take it kindly.
01:16:20Also keep in mind that there are elevators that might not have this function.
01:16:24For honey lovers out there, go ahead and raise your hand.
01:16:28If your pot of golden honey is crystallized, know that it is actually a good sign.
01:16:34Crystallized honey means that it hasn't been pasteurized, which means better product quality.
01:16:39With a decrease in temperature, the natural ingredient of honey, also known as glucose,
01:16:44will make it crystallize.
01:16:46Now try making the best of it.
01:16:48To add some texture to your oatmeal or toast, add a layer of crystallized honey and enjoy
01:16:53nature's sugar.
01:16:54And if you don't like crystallized honey, plop it in the microwave for a minute or two.
01:16:59Ah, winter and fall.
01:17:01You know what this means, right?
01:17:02Sweater weather.
01:17:04But there's nothing more annoying than wearing your beautiful wool sweater and itching yourself
01:17:09all the way through it.
01:17:11Actually I can be more annoying than that, but let's talk about itchy sweaters.
01:17:15To keep this from happening again, here's the secret.
01:17:18Turn your sweater inside out and soak it in cold water.
01:17:21Add 2 or 3 tablespoons of vinegar and let it sit for a while.
01:17:25Then drain the water.
01:17:27Now while the sweater is still wet, massage a generous amount of hair conditioner into
01:17:32the fibers of the wool.
01:17:34After letting it soak in the hair conditioner for about 30 minutes, gently press the excess
01:17:39water out of the wool and leave it to dry flat on a towel.
01:17:43There you go, no more itchy sweater!
01:17:46Any fast-food restaurant you go to will hand out small paper cups for customers to fill
01:17:51with their ketchup, mustard, or barbecue sauce.
01:17:54But if you're eating some chicken nuggets or trying to dip your burger into the cup,
01:17:58there's always that bit of sauce that seems impossible to reach.
01:18:02Next time, try unfolding the cup.
01:18:05It'll turn into a small paper plate, and this way you'll get all the ketchup you poured
01:18:10in the first place.
01:18:12Padlocks used in outdoor environments should be cleaned and lubricated every 3 months.
01:18:17Regular lubrication will help prevent padlocks from freezing in cold weather conditions.
01:18:22Look for the tiny hole on the bottom of the lock.
01:18:25Then pour oil into it, and there you go, it opens again!
01:18:30One thing we often neglect is a point in an ointment cap.
01:18:34These pointy surfaces were designed to help us break the tinfoil protection of the ointment
01:18:38tube.
01:18:39You just turn the cap over and break the ointment seal with its own cap, and there you go!
01:18:46After a long day of work, all you really need to do is a bubble bath.
01:18:50You turn on the hot water and let it run for a few minutes.
01:18:53You might even light a candle and pour some essential oils into the water.
01:18:57Then in comes the liquid soap.
01:19:00You stir the water until the entire surface of the tub water is crammed with bubbles,
01:19:05and make your way in.
01:19:06The bubbles in a bubble bath have a fundamental primary function.
01:19:10Their job is to preserve the water's temperature, just so you can have warm water for longer.
01:19:16Do you have sweaty feet?
01:19:18Weird question, I know.
01:19:19But if you're one of these people, here's some good news.
01:19:23Trouble is not lost.
01:19:24Try putting a dry teabag inside your shoes and storing it in a dry place for a while.
01:19:30The teabags will absorb the humidity and the smell off the soles of your shoes.
01:19:35So here I am thinking, shouldn't we have learned these things in school?
01:19:39So consider this.
01:19:41People started making ridge patterns on coins in past centuries to fight counterfeiters.
01:19:46In the old days, cheaters cut off the smooth edges of coins and used that metal to mint
01:19:51new money.
01:19:52But with ridges, it became impossible to hide the cutting.
01:19:57These small cylinders on the charging cables are called chokes or ferrite cores.
01:20:02They're magnetic iron oxide that helps to prevent electromagnetic interference.
01:20:07In simple words, they protect your device from faults.
01:20:10We all know about these little pockets on jeans where people used to keep their pocket
01:20:15watches.
01:20:16But what about these small metal buttons?
01:20:18They help hold the fabric together.
01:20:20Weavers put the buttons where the jeans can tear during moving and straining.
01:20:25These small holes on some backpacks were designed to tie extra gear to them.
01:20:29So you can pass ropes through them and tie sneakers if you don't want to keep them inside
01:20:34your backpack or in your hands.
01:20:37This tiny dot next to the camera on your iPhone is a microphone.
01:20:41It helps to get good quality of sound while taking a video.
01:20:45The Spotlight feature on your Mac can be used not only for a quick search of files and apps.
01:20:51It also works as a calculator.
01:20:53Just type in a mathematical problem you need to solve.
01:20:56Spotlight also uses internal dictionary data.
01:21:00Enter any word in the search bar, and you can get information about it.
01:21:04You've just bought a new bottle of oil.
01:21:07You're taking off the lid and looking at this little cork that you can tear off by pulling
01:21:11the loop.
01:21:12Take this thing out, but don't throw it in the trash.
01:21:16Put it back in an upside-down position to control the pour's flow by pressing your
01:21:20finger against it.
01:21:23Tiny ridges on the F and J keys on the keyboard help your fingers navigate during touch typing.
01:21:29When your index fingers are on these ridges, you know exactly where other letters are.
01:21:35The brushes on the sides of the escalators are not for polishing your shoes, but for
01:21:39your safety.
01:21:41These nylon bristles prevent your laces and clothes from getting inside the escalator's
01:21:45gears.
01:21:46Now, that wouldn't be good.
01:21:49Most door handles are made of brass.
01:21:51This type of metal is good for fighting microbes.
01:21:54Bacteria can't multiply that much on such surfaces.
01:21:58These public toilets' cubicles don't look private for a reason.
01:22:02Huge gaps at the bottom were created to make you want to get out of there as soon as possible.
01:22:08Thanks to this design, there are almost no cubes.
01:22:11You can use a plastic lid from soda cups as a coaster.
01:22:15It has the perfect shape to hold your drink and keep a table surface from getting wet.
01:22:20Don't turn the lid upside down.
01:22:22Just put it on the table the same way it was on the cup.
01:22:26If you're stuck in a car during an accident and can't open the doors, you can use bars
01:22:30from the detachable headrest to break the window and get out.
01:22:35Remember those small plastic discs under the bottle lids?
01:22:39This little thing helps preserve vacuum inside bottles, keeping soda in a fizzy state.
01:22:45You've probably watched food heating in a microwave at least once in your life.
01:22:49Exciting, I know!
01:22:51But why do the developers make the doors so dark?
01:22:54This black film is necessary to block electromagnetic fields.
01:22:59Tiny dots on padlocks next to the keyhole are designed to dry out the moisture if water
01:23:05gets inside the lock.
01:23:06Also, if the lock gets jammed or starts to rust, you can pour oil into it through this
01:23:11hole to fix the problem.
01:23:14A golf ball is covered with tiny craters for good aerodynamics.
01:23:18They're called dimples, and this design helps the ball fly further and more evenly.
01:23:25Some mugs have a little groove at the outside of the bottom.
01:23:28It helps water flow out and prevents it from accumulating when the cup is in the dishwasher.
01:23:35Sunglasses were first used not to protect your eyes from the sun.
01:23:38They use such glasses during Arctic expeditions.
01:23:41A huge amount of snow can blind you just like a bright flash.
01:23:45To save their eyes, they came up with these unique glasses.
01:23:50You can use any T-shirt not only for dressing but also as a protective layer for your luggage.
01:23:55Just put your clothes on your suitcase as a cover and don't waste time plastic wrapping
01:24:00it.
01:24:01A button on the back of the shirt collar is there to keep your tie under the collar.
01:24:06Yes, people don't use it as intended because all ties are thinner now, but this button
01:24:11is still there as a decorative function.
01:24:14And here's the initial purpose of a tie.
01:24:17They created it in 17th-century Europe to tighten the collar.
01:24:21This way, people protected their necks from a strong wind.
01:24:24Then, they got used to this part of the outfit and made it a must-have accessory for royal
01:24:30gatherings.
01:24:31Soft pom-poms on hats were first invented several centuries ago.
01:24:36Sailors used them to avoid hitting their heads against low ship ceilings and ledges.
01:24:41They make most clothes hangers from cedar wood since it contains many natural oils repelling
01:24:46moths that love to eat your clothes.
01:24:50A light bulb is spherical because such a shape allows the light to distribute evenly.
01:24:55Also, such light bulbs are cheaper and easier to produce.
01:25:00Ever found these pieces of fabric in new clothes?
01:25:03They're not just patches, but also testing subjects to use before washing.
01:25:08You can put this piece in the washing machine and see what happens to it.
01:25:12If everything is fine, then you can safely put your clothes in.
01:25:16Your ceiling fan has two modes of work – winter and summer.
01:25:20You need to find the switch on it, push it up to activate the winter mode, and down for
01:25:25the summer one.
01:25:26In summer mode, the fan pushes the air down.
01:25:30It pulls the air up in winter.
01:25:33Most people have this ground plunger in the bathroom.
01:25:36In movies, they use those to eliminate a blockage in the toilet.
01:25:40In fact, the plunger is to get rid of a blockage in the sink.
01:25:44For the toilet, you need another special device.
01:25:47The extra space under your oven is not for keeping pans and pots.
01:25:52You can put some dishes there.
01:25:54The heat of the stove will keep your meals warm.
01:25:56It's useful if you're waiting for friends late for dinner.
01:26:01You're taking a pack of popcorn out of a microwave after heating.
01:26:06See the little hole at the top of the popcorn bag?
01:26:09You can use it to get rid of small unpopped grains.
01:26:12Shake the pack over the plate, and all the grains will fall out through the hole.
01:26:17Almost all people use a travel pillow incorrectly.
01:26:21Usually they put two ends forward and lay their heads back.
01:26:24Try to turn the pillow on the other side.
01:26:27The arc should be under your chin, and the two ends should be directed back.
01:26:32Lay your head forward, and your neck will feel way more comfortable in this position.
01:26:37And you'll get a good nap.
01:26:39They create magnets in a horseshoe shape to increase their magnetic power.
01:26:44The blue part indicates the south pole, the red part the north one.
01:26:48The two poles work simultaneously and increase the attraction.
01:26:53Thanks to the perfect aviation design, most planes can fly a long distance even without
01:26:58an engine.
01:27:00In 1268, Roger Bacon made the first written mention on using telescope lenses for optical
01:27:06purposes.
01:27:08Magnifying lenses inserted in frames were popular for reading both in Europe and China
01:27:12at this time.
01:27:14So it's still a question if the West took it from the East or vice versa.
01:27:19If you find yourself in the middle of the sea without food, sorry, you can try fishing.
01:27:25You can use anything for bait – your phone, watch, keys.
01:27:29And you can use laces as a fishing line.
01:27:31Tie the bait and throw it into the water.
01:27:34And good luck catching the fish that swallowed your phone – it's going to be a whopper!
01:27:39You can turn over the tab on a lid of soda cans and use it to hold a cocktail straw in
01:27:45place.
01:27:46The blue half of the eraser wasn't originally created to delete the ink.
01:27:50Initially, the blue part erased inscriptions and drawings on thick paper.
01:27:55The red part couldn't do it without leaving streets, but the blue one handled this task
01:27:59perfectly.
01:28:01Most of us tear sticking notes off incorrectly.
01:28:05Try not to do it from below, but from the side along the licking line.
01:28:09The paper will stick to the wall for longer this way.
01:28:13Ever wondered what these two holes in the lollipop stick are for?
01:28:17All the time, you say.
01:28:19Well, when they put the bar in hot syrup, the liquid flows inside.
01:28:24It creates a solid attachment for the plastic.
01:28:27And so it goes.
01:28:31Imagine you're an art detective and your task is to explore the mysteries behind the world's
01:28:36most famous paintings.
01:28:38I'm talking about works from Da Vinci, Michelangelo, Picasso.
01:28:42So grab your magnifying glass, as this journey is about to begin.
01:28:48First off on your list is Rome.
01:28:51After enjoying delicious pasta, you head to the Sistine Chapel, home to the world's most
01:28:56famous ceiling.
01:28:57Oh, and you know how they say Michelangelo painted the frescoes lying down?
01:29:01This is just a myth.
01:29:03Actually, the painter created a complex system of platforms that allowed him to paint standing.
01:29:09You're checking out the creation of Adam, that fresco in the middle.
01:29:13The Italian artist Michelangelo, the author of this masterpiece, was widely known for
01:29:18his study of human anatomy.
01:29:21Art experts argue that the right part of the painting is an anatomically correct depiction
01:29:25of an enlarged brain.
01:29:27To proof check this, you try overlapping a picture of the organ and the artwork.
01:29:32It seems to be a match.
01:29:34The cerebellum, the optic nerve, and the pituitary gland are all there.
01:29:39Even the floating green scarf thingy appears to match the vertebral artery.
01:29:44Some researchers think it was Michelangelo's way of depicting knowledge and wisdom.
01:29:49But you have to sleep on it to decide what you think.
01:29:52Moving on, you catch a train and arrive in Florence.
01:29:56Time for a quick gelato break, then straight to the Accademia Gallery.
01:30:01One of art's most celebrated sculptures is waiting for you inside, Michelangelo's David.
01:30:07David is a 17-foot tall marble wonder.
01:30:11It was carved for about three years.
01:30:13The mystery surrounding it is to figure out the statue's true expression.
01:30:18Looking at him from below, you'll think his face is serene and peaceful.
01:30:22But art historians argue that this work was largely misunderstood.
01:30:26Apparently, his body hides a very different story.
01:30:31Take a closer look, and you'll notice his brows are frowning, and the veins in his arms are popping out.
01:30:37That doesn't look too relaxed, does it?
01:30:41Michelangelo's idea was to depict David right before an important confrontation.
01:30:45So maybe he wasn't all that serene after all.
01:30:50Italy is so rich in art, you can't leave just yet.
01:30:54You're still in Florence.
01:30:56You pay a visit to the famous Uffizi Gallery.
01:30:59Many famous paintings are hosted by this museum.
01:31:02But you're checking out Botticelli's Primavera, or Spring.
01:31:07This artwork is mysterious from the get-go.
01:31:10Experts can't say the exact year it was commissioned.
01:31:13It remained untitled for years, until the painter Giorgio Vasari finally came up with a name for it, usually.
01:31:21When critics and viewers admire this painting, they focus on the figures in the foreground.
01:31:26But in this case, the actual work lies in that Botticelli painted over 46 different plant species, with almost identical precision.
01:31:35And, oh, in the painting overall, these plant figures are repeated over 200 times.
01:31:41Unbelievable!
01:31:42I'd say the last visits were full of impressions, weren't they?
01:31:46Ready to keep going?
01:31:47A plane ride later, you arrive in Paris, the city of lights, berets, and the famous Mona Lisa.
01:31:55You go through the Museum de Louvre and come to Leonardo da Vinci's masterpiece, La Gioconda.
01:32:02There are many theories regarding this work of art, and you dive into some of them.
01:32:07A strong case has been made that the Mona Lisa could be a self-portrait of da Vinci himself.
01:32:12Historians have thoroughly compared da Vinci's face and that of the Mona Lisa, and guess what?
01:32:18They appear to be strikingly similar.
01:32:21Oh, and then there's the smirk theory.
01:32:24Dentist and art expert Joseph Bartowski claims to have discovered the secret behind Mona Lisa's smirk.
01:32:31He says her tight facial expression is a typical indication of someone who lost their front teeth.
01:32:38Could it be so?
01:32:40Also, in 2010, the Italian Committee for Cultural Heritage found a collection of symbols hidden in the painting.
01:32:47These are only visible through highly technological magnifying lenses,
01:32:52but they showed that Leonardo inscribed an LV inside Mona Lisa's right eye.
01:32:58Experts guess that this is da Vinci's signature.
01:33:01But the other symbols, a CE in the left eye and a 72 in the arch of the background bridge, are still very mysterious.
01:33:11Phew, you covered a lot of ground on this one.
01:33:14Ah, of course, at the end of your visit, remember to test if her eyes really follow you around.
01:33:21Now you're headed to Amsterdam to check out the Rijksmuseum.
01:33:25You came to see a specific Rembrandt painting that hides a mysterious story.
01:33:29The Night Watch is one of Rembrandt's most famous paintings,
01:33:33but experts argue that the name of the painting and its content are mismatched.
01:33:38Let's take a closer look.
01:33:40The painting depicts a large group ready to embark on a mission.
01:33:44Rembrandt's technique is called chiaroscuro, highlighting the contrast between light and shade.
01:33:50Until 1947, art critics believed the painter was depicting a nighttime scene.
01:33:55But when the painting was cleared of a thick dust layer,
01:33:59it became clear that the scene was happening in broad daylight,
01:34:02with the sun streaming down from the top left.
01:34:05Now it's too late to change its name to The Day Watch.
01:34:09While in Amsterdam, you find a museum dedicated to Van Gogh's art.
01:34:14Did you know that he painted over 900 paintings during an impressive period of only 10 years?
01:34:20Anyway, the Van Gogh Museum hosts the biggest collection of yellow sunflower paintings
01:34:25you'll probably see in your life.
01:34:28Actually, almost all of Van Gogh's paintings feature dominant yellow shades.
01:34:32This particularity of his art may be a result of how he saw the world.
01:34:37Some art experts have speculated that one of Van Gogh's remedies changed his color perception,
01:34:43making him see more yellow around him.
01:34:46Okay, so this trip just keeps getting better.
01:34:50The next stop on your list is the United Kingdom.
01:34:53Then, on to the National Gallery.
01:34:55You may spend hours looking at Jan van Eyck's painting Arnolfini Portrait
01:35:00and not see anything out of the ordinary.
01:35:03In the foreground, a couple holds hands and stares at the viewer.
01:35:07But if you zoom in on the mirror on the wall, you'll see two more people in the room.
01:35:13Art experts say the male figure in the painting has his hands raised
01:35:17to greet these two people seen in the mirror,
01:35:19and that one of the figures is van Eyck himself.
01:35:22Oh, and that's not the only watermark the painter left.
01:35:26Above the mirror, you'll see his flamboyant signature.
01:35:29Jan van Eyck was here, 1434.
01:35:33And speaking of people trying to sneak into their art,
01:35:36Caravaggio, the renowned Italian Renaissance painter,
01:35:39left a little Easter egg in one of his famous paintings, Bacchus.
01:35:43This one is a bit difficult to spot.
01:35:46In the half-filled jar in the bottom left corner of the painting,
01:35:49there is a tiny self-portrait of the painter himself, hidden amongst the liquid.
01:35:54To see the image clearly, one needs the help of sophisticated technology,
01:35:58or at least a very efficient magnifying lens.
01:36:01But it's there, a male figure, aka Caravaggio, with a brush in his hand.
01:36:07Fun fact, the tiny self-portrait was first noticed in 1922,
01:36:12over 300 years after the painting was completed.
01:36:15It was forgotten due to poor conservation.
01:36:19To finish the trip, you fly overseas across the Atlantic, all the way to Chicago.
01:36:24The enormous collection of the Art Institute
01:36:27hosts a well-known painting by Pablo Picasso, The Old Guitarist.
01:36:31This painting's secret is so well-hidden
01:36:34that it also needs the help of X-ray machines and super-fancy technology.
01:36:38But the results are worth it.
01:36:40The readings show that Picasso painted The Old Guitarist
01:36:44on top of another unfinished painting.
01:36:46We can clearly see the outlines and shapes of a half-drawn female figure
01:36:51that Picasso gave up on mid-work.
01:36:54The emerging artists of the time used that way of saving money quite often,
01:36:58as canvases were expensive.
01:37:02This was quite a tiring world trip, wasn't it?
01:37:05Get some rest, Sherlock of Art.
01:37:07Road and construction workers are usually dressed in orange
01:37:10because the bright orange hue is visible even in bad weather.
01:37:14It's the most effective color to attract attention and alert people.
01:37:18No wonder lots of safety jackets and traffic cones are orange as well.
01:37:22The stop sign has an eight-sided shape to help drivers recognize it easily,
01:37:26even if they see it from the back.
01:37:28And when the signs weren't reflective yet,
01:37:30the octagon shape prevented drivers from confusing the stop sign
01:37:34with any other at night.
01:37:36The rumble strips on the side of the road
01:37:38are placed there to alert drivers who doze off behind the wheel.
01:37:42When their tires move over these strips,
01:37:44the noise and vibration work like an alarm clock.
01:37:47There are magnetic locks on fuel hoses at gas stations.
01:37:51They come in handy if someone drives away with the gas nozzle
01:37:53still attached to their car.
01:37:55In this case, the lock detaches the hose automatically.
01:37:58Oh, that's embarrassing.
01:38:00Gasoline looks like a rainbow in a puddle because it can't mix with water.
01:38:04It forms a thin membrane over it.
01:38:07When light reflects from it and the water at the same time,
01:38:10you've got a rainbow.
01:38:12A triple handle on a jerry can is there to make it easier
01:38:16for two people to carry it and distribute fuel evenly.
01:38:19Gas cans often have a second hole that actually needs to be uncapped too
01:38:23before you pour the gas.
01:38:25The air passage will prevent it from pouring out,
01:38:28so no more fuel waste.
01:38:30Most gas cans have two holes with caps, a bigger and a smaller one.
01:38:35You're supposed to uncap the smaller hole before pouring gas
01:38:37inside the bigger one.
01:38:39It'll prevent the liquid from glugging and spilling all over your clothes
01:38:43and the ground.
01:38:44Another little thingy we often neglect is a point on an ointment cap.
01:38:49Most tubes are usually sealed with a plastic film or a foil,
01:38:52and opening it with your fingernails isn't the best idea.
01:38:55A point easily opens even the most safely sealed tube.
01:39:00You can use most screwdrivers together with a wrench to create more torque.
01:39:05Just place the wrench over the handle of the screwdriver.
01:39:08This way, you'll need to apply a lot less force than before.
01:39:11You'll also be able to get to hard to reach areas more easily.
01:39:16They install cameras in shops, banks, and hospitals to monitor everything.
01:39:21If something happens, you can call the police or rescuers.
01:39:24The camera really helps to solve a lot of problems.
01:39:27Why are there no cameras on planes?
01:39:30The crew keep order on the plane, but they
01:39:32won't be able to do anything if something serious happens.
01:39:36Besides, there's nowhere to run on the plane.
01:39:39During the flight, the cameras are useless.
01:39:41And after the flight, the words of the passengers
01:39:44work ideally instead of cameras.
01:39:46So if cameras do no good, then why spend money on them?
01:39:51Water is great at cleaning stuff because it has triangular molecules.
01:39:55They're made of one oxygen and two hydrogen atoms, H2O.
01:39:59Such molecules have slightly different charges on their opposite sides,
01:40:03pretty much like magnets.
01:40:05That's why water easily sticks to other molecules,
01:40:07including those that make up dirt.
01:40:10Lots of private houses have triangular shaped roofs
01:40:12because this allows rain, snow, and fallen leaves to slide off the slope.
01:40:17If all this stuff piled up on top of your house,
01:40:20one day your roof would collapse.
01:40:23When a storm is coming, clouds seem to turn dark.
01:40:26But it's just an illusion.
01:40:27Thin clouds on a sunny day let the light through easily.
01:40:31They also scatter all the colors of the light spectrum.
01:40:34This makes us perceive the clouds as white.
01:40:36But the thicker the clouds are and the more water droplets they contain,
01:40:40the less light they let through and the darker they look.
01:40:44A good doorknob is the one made of brass, bronze, or some copper alloys.
01:40:49These metals have an anti-germ effect.
01:40:52Bacteria spread way slower on them.
01:40:55They also get rid of germs pretty fast, within a couple of hours.
01:40:59Nope, it doesn't mean you don't have to wash your hands.
01:41:02Diamonds have such symmetrical shape to show you their brilliance.
01:41:06Initially, the gems aren't so beautiful.
01:41:09They go through several stages of cutting
01:41:11and then become pieces of elegance.
01:41:14Most of these stones have a round shape with slightly pointed corners.
01:41:18Diamonds shine the brightest in this shape.
01:41:21Why are there two holes in the socket?
01:41:24The left hole is neutral.
01:41:25The right hole is not.
01:41:27And the gap underneath is ground.
01:41:30Electricity needs to flow through the chain.
01:41:32The current flows from the hot slot, passes through your phone charger,
01:41:36for example, and then goes through the neutral hole.
01:41:40Ever wondered what that small pocket on your jeans is for?
01:41:43People used to wear watches on chains.
01:41:45That small pocket was meant for it.
01:41:48Now, almost no one wears such a watch, but the pocket remains.
01:41:52You can still keep something small in there, like a ring.
01:41:55In London, there are some poles that look like street lamps,
01:41:58but there are no bulbs.
01:42:00Well, their official name is stink pipes,
01:42:03and they're a thing of the past now.
01:42:05But they used to come in handy back in the 19th century.
01:42:08These hollow poles would vent away the air and explosive gases
01:42:11with bad smells to prevent, shall we say, unwanted consequences.
01:42:17Most kitchen shears have metal plier-like teeth in the middle.
01:42:20Between the handle grips, they can help you crack nuts,
01:42:23crab shells, and other tough products.
01:42:26You can also open jars and bottles or remove herb stems with their help.
01:42:31Leather often looks dull to the eye because it's covered
01:42:34with itsy-bitsy scratches and scrapes.
01:42:37They scatter the light that hits the material.
01:42:39When you coat your shoes in a layer of wax, you fill these tiny crevices.
01:42:44The surface becomes smoother, and the rays of light bounce off it more evenly.
01:42:48That's why the leather looks shiny.
01:42:51Highlighters are filled with a special semi-transparent fluorescent ink
01:42:55that can glow in dim light.
01:42:57Yellow and light green hues are the most popular
01:43:00because they don't prevent you from seeing the text
01:43:03after black and white photocopying.
01:43:05Photocopiers perceive yellow and light green marks as very pale
01:43:09and don't print them.
01:43:11They make magnets shaped as a horseshoe
01:43:13because this increases the magnetic force.
01:43:15Colors matter, too.
01:43:17The blue part indicates the south pole.
01:43:19The red part, the north pole.
01:43:21The two poles work simultaneously and increase the attraction force.
01:43:26The dime-sized holes in elevator doors is actually a keyhole.
01:43:31If the doors get stuck, an operator can open them manually thanks to this hole.
01:43:35They'll just insert a special key.
01:43:38The tiny hole in the airplane window is there to balance air pressure.
01:43:43The window has three layers.
01:43:45The outer pane is extremely sturdy.
01:43:48It can withstand air pressure differences during takeoff and landing.
01:43:51The inner pane, which is the closest to you, is made of cheaper materials.
01:43:56It prevents potential damage to the window.
01:43:58The hole itself is in the middle pane.
01:44:01It not only balances the pressure but also prevents the window from fogging.
01:44:06Escalator brushes are there for your safety.
01:44:09They don't allow you to come too close to the edge of the escalator.
01:44:12This way, your clothes won't end up between the steps.
01:44:16You see the sun as yellow or orange because the atmosphere of our planet scatters such
01:44:21colors as blue, green, and violet.
01:44:24This is also why the sun looks warmer at sunrise and sunset.
01:44:29Go shopping for some oranges, and I'm sure you'll get them in a red mesh bag.
01:44:33You'll rarely see them lying around without one of those.
01:44:36It's pure marketing, and that color isn't a random choice.
01:44:39When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to
01:44:45you.
01:44:46So, you're more likely to buy them, right?
01:44:48Lemons are usually sold in green mesh bags for a similar reason.
01:44:52If you pack them in red, they'll appear more orange.
01:44:55Green goes better with yellow and makes those lemons stand out.
01:45:00Mattress manufacturers make a limited number of different mattresses, and the only way
01:45:04to make them look different is to come up with a fancy stitching pattern.
01:45:08Two mattresses of two different companies might be the exact same quality but cost differently.
01:45:14Most people will never know it and will decide that different patterns mean something in
01:45:18terms of quality.
01:45:19So, when shopping, don't mind the pattern at all.
01:45:23Almost all hotels have white bedsheets.
01:45:26They choose this color specifically to show how high their standards of cleanliness are.
01:45:31The whiter and brighter the sheets are, the more luxurious the hotel seems.
01:45:35It's much easier to see dirt and stains on white linen.
01:45:38It's like proof that you've checked into a clean room.
01:45:41You're trying on a pair of jeans, a dress or a jacket, and are about to dig your hand
01:45:46into the pocket when… you realize there's no depth to it.
01:45:50The pocket is simply not there.
01:45:53But why would anyone create pockets you can't put anything in?
01:45:57And now would be a good time to pick your iPhone up from off the floor.
01:46:01Well, the reason for fake pockets is simple.
01:46:04If a clothing item has a specific cut or shape, pockets may spoil it.
01:46:09They can alter the item's shape either in the warehouse or already on the retail rack.
01:46:14The solution?
01:46:15Getting rid of pockets in key areas.
01:46:17Plus, fake pockets are obviously cheaper, and they don't get stretched out.
01:46:22Interestingly, this practice goes back to the 17th century.
01:46:26That's when pockets were actually removable.
01:46:29They resembled small bags, and women, for example, could move them from one outfit to
01:46:34another.
01:46:35Unfortunately, it was also very convenient for pickpockets.
01:46:39They could grab such a pocket and run off with it.
01:46:42Then clothes became more streamlined, and slim pockets started to be sewn right into
01:46:47them instead of attachable bags.
01:46:50This was believed to make the shape of a person's silhouette more alluring.
01:46:54But soon, slimmer skirts came into fashion, and pockets went out of it.
01:46:59And people started using handbags instead.
01:47:02These days, most pockets are real.
01:47:05But some of them are still fake.
01:47:07So how can we make sure that we don't actually turn a fake pocket into a hole, thinking it's
01:47:12a real one?
01:47:13Well, first of all, take a look at the stitching along the edge of the pocket, where it's
01:47:17supposed to open up.
01:47:19If you see a single loose thread, just snip a piece of it and start pulling gently.
01:47:24If the pocket is real, the thread will easily come out.
01:47:28But if you feel that the stitching won't budge, most likely, you have a faux pocket
01:47:33on your hands.
01:47:34If this is the case, just leave it be.
01:47:38Now let's move on to some other everyday objects that may be hiding some secrets.
01:47:43For example, those lines on some kinds of chips.
01:47:46For one thing, they help with the distribution of spices and seasonings.
01:47:50In other words, all those substances that make your chips taste like cheese are mostly
01:47:55stored inside the lines.
01:47:57Plus, the lines make chips crunchier.
01:48:00Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
01:48:07Yellow and light green hues are the most popular because they don't prevent you from seeing
01:48:11the text after black-and-white photocopying.
01:48:15Photocopiers perceive yellow and light green marks as almost non-existent and don't print
01:48:19them.
01:48:20Now, back in the day, the first jeans had one problem.
01:48:25Photocopiers and miners, who were the original jeans wearers, put too much pressure on the
01:48:29poor piece of clothing.
01:48:31As a result, the seams couldn't withstand the stress and tore.
01:48:35So, tiny metal studs were invented to prevent this from happening.
01:48:40Most metallic zippers have a hidden lock inside them.
01:48:43That's why you shouldn't leave the zipper handle in an upward position.
01:48:47When you pull it downwards, it automatically locks.
01:48:50It's all thanks to several tiny grooves hidden underneath the handle.
01:48:54Now, about those horizontal lines on plastic bottles.
01:48:58They help hold bottles up.
01:49:00Some bottles are produced from soft plastic.
01:49:03Without the lines, they wouldn't keep their shape.
01:49:05Instead, they would twist easily or even break.
01:49:09Bath foam isn't only for fun or a nice smell.
01:49:12It helps regulate the temperature too.
01:49:14The bubbles keep the water hot, and you can enjoy your bath a bit longer.
01:49:19With or without your rubber ducky Ever noticed that layer of clear liquid in
01:49:24gel pens?
01:49:25It's called the ink follower or stopper fluid.
01:49:29The gel in such pens contains pigment particles dissolved in a polymer solution.
01:49:34The gel should be thick enough to keep the pigment particles suspended, but also thin
01:49:39enough to flow first onto the ball and then the paper.
01:49:43The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating
01:49:48or leaking out.
01:49:50Without this transparent fluid, your gel pen wouldn't function.
01:49:53The fluid always stays in one position and doesn't get dissolved with the gel.
01:49:58Neither does it move backward or flow out of the pen.
01:50:02The holes in the bottoms of your earphones allow air to circulate up and through the
01:50:06speakers.
01:50:07It allows to increase low frequencies, making the bass sound deeper.
01:50:12The quality of the sound also becomes much better.
01:50:15Some plastic milk containers have dents on their sides.
01:50:18Try as they might, they just cannot park without some damage.
01:50:22Nah, I made that up.
01:50:24These dents serve several purposes.
01:50:26For one thing, when milk spoils, this process usually causes swelling and high-pressure
01:50:31buildup inside the container.
01:50:33Oh boy!
01:50:34That's when the dent comes in handy.
01:50:36It pops out and doesn't let the jug blow up.
01:50:39Plus, if you ever decide to freeze the milk, it will expand like any other liquid.
01:50:44And then again, the indentation will pop out and prevent the container from breaking inside
01:50:49your freezer.
01:50:50That's a good thing.
01:50:53Airplane windows have rounded edges, and that's a crucial safety measure.
01:50:57It prevents aircraft accidents.
01:50:59Weak spots are usually situated in the corners.
01:51:02If airplane windows were square or rectangular, each of them would have 4 potential weak spots.
01:51:08Under pressure, they would collapse.
01:51:11If you look closely at a tram's overhead lines, you'll see that its contact wires
01:51:16zigzag back and forth instead of going in a straight line.
01:51:20The thing is that all trams have pantographs attached to their roofs.
01:51:24The upper part of the pantograph is gradually worn down by the overhead wire, and eventually
01:51:29needs to be replaced.
01:51:31To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag
01:51:37patterns.
01:51:38As the tram moves, the pantograph slides along the wire, and it wears down evenly.
01:51:44You might've wondered why some gas cans have two holes with caps – one bigger and
01:51:49one smaller.
01:51:50Before, I thought that the little hole was used when you poured something into a smaller
01:51:54container.
01:51:55But I was wrong – a very infrequent occasion.
01:51:59In reality, you're supposed to uncap it before you pour the gas inside the bigger
01:52:03hole to prevent it from glugging and spilling on your clothes and on the ground.
01:52:09Most of the buttonholes on a shirt are vertical, but the top and sometimes bottom ones are
01:52:15horizontal.
01:52:16The reason is simple – these two buttons slip out more often than others.
01:52:20Luckily, producers have found the solution that can prevent these buttons from slipping
01:52:24out – horizontal buttonholes.
01:52:27What engineering!
01:52:28Buttons tend to slip out less from such buttonholes.
01:52:32Big sachets of sugar or salt are easier to open than many people think.
01:52:36There's no need to tear off one of the ends.
01:52:39The right way is actually to tear them down the middle.
01:52:43Some boots have loops sticking out on the back.
01:52:46Their main purpose is to help you pull your shoes on easier.
01:52:49Just tug on the loop while you're pushing your heel into the boot.
01:52:53You can also use these loops to hang your boots on a hook when they're dirty or when
01:52:57you want to dry them after washing.
01:52:59Or you can run your laces through the loop if you want to tie them around your ankle.
01:53:04When you're on board the plane, you might spot a little triangle over your seat.
01:53:09Such triangles show the flight crew the best spots to check the plane's flaps through
01:53:13the window, just in case they're flapping.
01:53:16If your shoes are really slippery, just take a bit of sandpaper and rub it on the soles
01:53:21for better traction.
01:53:22They'll become more grippy, and you'll be able to wear them out in the rain.
01:53:27If they get too wet, they might turn griping, but that's only if you have talking shoes.
01:53:33If you drill several holes at the bottom of your garbage can, putting in and taking out
01:53:38trash bags will become much easier.
01:53:40You won't have any problems with suction.
01:53:44You can usually find some silica gel in bags, shoes, and many other things you buy.
01:53:49This shell absorbs excess moisture.
01:53:51Don't throw it away.
01:53:53Each time your shoes get wet, put a few packets of silica gel inside.
01:53:58The thermos wasn't actually invented to keep your coffee warm.
01:54:02It was made by a Scottish scientist who just wanted a safe place to put his chemicals at
01:54:06a stable temperature.
01:54:08So he took two bottles, put the smaller one inside the bigger one, and vacuumed out the
01:54:13air between them.
01:54:15Well, anyway, thanks for the hot coffee!
01:54:20New iPhone models with large screens have a convenient option called Reachability.
01:54:25Thanks to this function, you don't have to struggle to reach the top of the screen.
01:54:29This feature can be found in the phone's accessibility settings.
01:54:33It allows you to lower your screen down.
01:54:35The rumble strips on the side of the road are there to wake up sleepy drivers who doze
01:54:39off behind the wheel.
01:54:41When your tires drift off onto these strips, the noise and vibration work like an alarm
01:54:46clock.
01:54:47Most kitchen shears have metal plier-like teeth in the middle.
01:54:50They allow you to use the device for multiple purposes.
01:54:53They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.
01:54:58You can also open jars and bottles with their help.
01:55:01Some people even use these teeth to remove stems from herbs.
01:55:05If your audio jack has three rings, it means your device can produce stereo sound, and
01:55:10your earphones have the microphone function.
01:55:12The black grating on a microwave oven door is called a Faraday shield.
01:55:17It stops microwaves from getting away.
01:55:19If they do, your food won't cook properly.
01:55:22The digits on an egg can tell you a lot about the product.
01:55:26In many countries, there's a special labeling system.
01:55:29The first number indicates the method of production.
01:55:31The following two-letter code stands for the country where the egg was produced.
01:55:35And then you can find a registration number.
01:55:38It indicates the laying hen establishment.
01:55:40The first number in this code can vary from 0 to 3.
01:55:43Zero means it's an organic egg.
01:55:461. It's a free-range egg, which means it was produced by a hen that was allowed to
01:55:50wander around outdoors.
01:55:522. Stands for an egg produced in a deep litter indoor housing.
01:55:553. You're about to buy a cage farming egg.
01:56:00A black band that runs along the edges of your windshield is called the frit.
01:56:04It's a baked-in ceramic paint that starts as solid black bands near the edge of the
01:56:08windshield.
01:56:09Then, it dissolves into smaller dots.
01:56:12The frit makes the glass rougher, and the adhesive sticks to it better.
01:56:16The frit protects the urethane sealant.
01:56:18It's the substance that fixes the glass to the frame.
01:56:21It also prevents the sun's ultraviolet rays from melting the adhesive.
01:56:25As for the black dots, they help distribute the temperature in the car more evenly.
01:56:29They're aesthetically pleasing too.
01:56:31Without them, the contrast between the glass and the dark band would be too obvious.
01:56:37If you see a pair of jeans with an extra loop, those are special jeans for cyclists.
01:56:42They're likely to belong to the commuter clothing line, and the loop's main purpose
01:56:46is to hold your bike lock.
01:56:49Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.
01:56:55These rings are added so that you can connect the sliders with the lock and keep pickpockets
01:56:59away.
01:57:01Keyboards come with little legs.
01:57:03They were designed for you to be able to tilt your keyboard.
01:57:06This way, you can actually see which keys you're hitting.
01:57:09At the same time, a flat keyboard doesn't make your wrists so tired, and people who
01:57:13can type without looking at the keyboard don't need those legs whatsoever.
01:57:17An olive spoon is usually made of stainless steel and has a small hole cut in its bowl-shaped
01:57:23head.
01:57:24The main purpose of this utensil is to lift olives, cherries, pickled garlic, and other
01:57:28products from liquid-filled jars, cans, or bowls.
01:57:32The hole in the middle allows you to drain the liquid gathering in the spoon fast and
01:57:36easily.
01:57:37What'll they think of next?
01:57:39Donuts are shaped like rings because, otherwise, they get overdone at the edges and remain
01:57:43uncooked and gooey inside.
01:57:46Make a hole in the center, and both the outsides and the insides will be cooked at the same
01:57:50time.
01:57:51Round-shaped donuts with no holes are usually filled with custard, cream, or jelly.
01:57:58Large donuts don't have any corners, which means there are fewer weak spots for the filling
01:58:02to spurt out from.
01:58:04If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.
01:58:09To avoid such situations, flip up the tabs on the sides of the juice box.
01:58:14You can use them to hold your drink.
01:58:16Some cars have a tiny coffee cup sign on the dashboard.
01:58:19It's the vehicle's anti-drowsiness mechanism.
01:58:23Some manufacturers equip their cars with a drowsiness detection system.
01:58:26It analyzes the speed, wheel angle, and lane deviations and figures out if it's time
01:58:32for the driver to take a break.
01:58:34If it is, the vehicle makes several audio signals and the coffee cup sign starts to
01:58:38flash.
01:58:40Produce stickers on fruit and veggies you get at the supermarket are full of information.
01:58:45If there's a 4-digit code on the sticker, the product was grown conventionally.
01:58:49In most cases, it also means that pesticides were used in the process.
01:58:53If the product is organic, its sticker has 5 digits, and the first one is 9.
01:58:59Genetically modified products also have a 5-digit code, but the first number is 8.
01:59:05Sugar used to be sold in sugar loaves.
01:59:08Those were tall, hard cones.
01:59:10At those times, to get sugar ready for tea, people had to use special hammers to break
01:59:15a loaf apart first.
01:59:17After that, they cut the sugar into smaller and more nicely shaped lumps.
01:59:21Maybe in the middle of the 19th century, people invented the first press that cut sugar
01:59:25into cubes.
01:59:27This way, the product was easier to store and transport.
01:59:30A little hole in the end of your wrench can provide your screwdriver with some extra torque.
01:59:35Just slide the end with the hole over the screwdriver.
01:59:38You can also use this method when the angle is awkward.
01:59:41While driving, when it's already dark, you might get blinded by the headlights of the
01:59:45car moving behind yours.
01:59:47If you have a manual rear-view mirror, find a tab at the bottom and flip it.
01:59:52The mirror has a reflective material behind its glass.
01:59:55By flipping the tab, you change the angle of this material, dimming the lights in the
01:59:59mirror.
02:00:01Most ice cream scoopers come in different colors.
02:00:03It has nothing to do with aesthetics.
02:00:06The color indicates the size of the scoop.
02:00:08This way, you can easily figure out how many scoops you'll need to fill 32 oz.
02:00:13Wow, a 32-ounce sundae, sign me up!
02:00:17Some caps on small tubes are hollow on top and have a little spike inside.
02:00:21Its purpose is to break the foil sticker sealing the tube.
02:00:25The neck fits right in this hole, and the spike is designed to break the seal.
02:00:29This way, you don't need to tear the tiny foil seal off with your fingers.
02:00:33The letter R in a circle on the product's packaging means that the trademark is officially
02:00:38registered.
02:00:40Once it's done, the trademark's owner has the right to place this letter on all their
02:00:44products.
02:00:45You can also sue anyone who tries to use their trademark.
02:00:48A gas pump usually has a small metal latch or hook on its handle.
02:00:53That's a trigger lock.
02:00:54You can use it to lock the handle in the open position.
02:00:57Then the gas will keep pumping even if you walk away.
02:01:01Coins used to be shaped randomly or have no shape whatsoever in the past.
02:01:05Dishonest people used it to their advantage.
02:01:08They stole valuable metals the coins were made of by chipping their corners off.
02:01:12It was illegal, and to prevent this kind of fraud, round coins were invented.
02:01:17After that, it became easy to instantly notice when a coin had been fiddled with.
02:01:22Those two holes in a lollipop stick are there to hold the candy in place.
02:01:27When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.
02:01:32Now your sweet is there to stay.
02:01:35Fabric squares that come with clothes are for you to try out your cleaning products
02:01:38on them first.
02:01:39This way, you won't ruin the entire item once you decide to wash it.
02:01:44The holes in the bottoms of earphones allow air to circulate up and through the speakers.
02:01:48It helps to increase low frequencies, making the bass sound deeper.
02:01:53The sound quality also becomes much better.
02:01:55Don't I sound better?
02:01:57Thank you!
02:01:58You can adjust your stapler so that it staples documents together only temporarily.
02:02:02It's done by rotating the crimp area.
02:02:05Most staplers have two options for stapling.
02:02:07One is standard, but the other side bends staples away from the center.
02:02:11Later, when you don't need them anymore, you can easily remove them by hand.
02:02:16If you store peanut butter jars upside down, the oil will move to the bottom, and all the
02:02:21solids will be on top.
02:02:23Hey, don't laugh, that matters to some people.
02:02:26You don't want to get caught with your peanut butter down!
02:02:30That's it for today!
