FunTranscript
00:00You may have already noticed the stripes on some types of chips.
00:04Well, on the one hand, they facilitate the distribution of spices and seasonings.
00:09In other words, the substances that give your chips a cheese taste are mainly stored inside these stripes.
00:16And on the other hand, the stripes also make the chips more crispy.
00:21Some cars have a small coffee cup-shaped indicator on their dashboard.
00:26This is the vehicle's anti-sleeping mechanism.
00:29Some manufacturers equip their cars with a sleep detection system.
00:34This system analyzes speed, wheel angle and trajectory deviations to detect when it is time for the driver to take a break.
00:42If this is the case, the vehicle emits several sound signals and the coffee cup-shaped indicator starts to blink.
00:49Some plastic milk bottles have recesses on the sides.
00:54They have several functions.
00:56For example, when the milk boils, this process usually leads to inflation and an increase in pressure inside the bottle.
01:03It is at this moment that the recess becomes useful because it accuses the pressure and time preventing the bottle from exploding.
01:10In addition, if you decide to freeze the milk, it will dilate like any other liquid.
01:16And again, it is the recess that will change and prevent the bottle from bursting inside your freezer.
01:24You may be wondering why jerrycans have three handles.
01:28This is a clever idea from the designer.
01:31So, if you carry the container alone, you can only use the central handle to distribute the weight evenly.
01:39But if your friend wants to help you, each of you can grab the side handle.
01:44Did you know that the first jeans had a problem?
01:48Indeed, the workers and miners who were among the first to wear jeans, exerted too much pressure on this poor fabric.
01:56As a result, the seams did not resist the tension and tore.
02:00To avoid this, tiny metal nails were invented.
02:05The sticker notes come off relatively easily because the adhesive is evenly distributed on the paper.
02:11In the form of small drops.
02:14Only some of these drops touch the surface of the object on which you stuck the note.
02:19Which explains why, when you take off a post-it and stick it on something else, it continues to stick.
02:26And this until all the glue is used or covered with dirt.
02:31Soda bottles are always filled in such a way that there is a space between the liquid and the cap.
02:37And this is due to the fact that soda contains carbon dioxide.
02:41A gas that can spread when the bottle is heated.
02:44If there was no space in the bottle, it could burst under the effect of the pressure exerted inside.
02:50In addition, by opening your drink, the gases escape in the form of bubbles.
02:54And, without this space, it would risk overflowing.
02:58The space provided also allows to solve this problem.
03:02Dental floss is very useful for teeth, but it can be difficult to use because it regularly slips from the fingers and gets tangled.
03:10To avoid these problems, cut a piece of dental floss and tie these two ends together.
03:15It will be much easier to use and will not hurt your fingers.
03:20Let's take a look at these horizontal lines on the plastic bottles.
03:24These allow the bottles to keep their shape.
03:27Some bottles are made with flexible plastic.
03:31Without these lines, these bottles would not be able to keep their shape over time.
03:36And they would easily twist, or could even break.
03:40The round and flexible part located under the capsule of a soda bottle prevents the gases from escaping.
03:46Without it, your soda would become flat in no time.
03:50Probably even before you bought it.
03:53If you do not have a place to put your dental floss after using it,
03:57cut its flat end at the level of the first groove and place it on the table.
04:02This allows you to rest the used part of your dental floss on the wrinkled part so that it does not touch the table.
04:09You can also make a fortune support for disposable chopsticks.
04:14These have an extra piece at the end.
04:17Break this piece before separating the chopsticks.
04:20When you want to take a break, all you have to do is simply place the chopstick on this... support.
04:27Donuts have a ring shape because, without the hole in the middle,
04:31they may be overcooked on the edges, but not cooked and sticky inside.
04:36With a hole in the middle, the outside and the inside are cooked and ready to be consumed at the same time.
04:44Have you ever noticed this layer of transparent liquid in gel ink pens?
04:49This is what is called the ink follower.
04:52The gel of these pens contains pigment particles dissolved in a polymer solution.
04:57The gel must be thick enough to hold the pigment particles in suspension,
05:01but also thin enough to flow first on the ball, then on the paper.
05:06The main task of the liquid is to create a barrier to prevent the gel from evaporating or flowing.
05:12Without this transparent fluid, your gel pen would not work.
05:16The liquid remains in the same position and does not dissolve with the gel.
05:20It does not move back either and does not flow out of the pen.
05:25Some buttoned shirts have a hidden button behind the collar.
05:29It is mainly used to prevent the tie from overflowing.
05:33Here is how to protect your bank card from potential scams.
05:37Take a marker and mask the last four numbers.
05:40You can also use a sticker that is easy to remove and place on the security code.
05:46Have you ever had a guest who, unfortunately, did not use his underglaze?
05:51Take a hair dryer and hold it a few centimeters from the stain.
05:55Plug it in over medium heat for a few minutes to evaporate the trace.
05:59If a discolored trace persists, mix the same amount of vinegar and olive oil in a bowl.
06:05Apply it to the marked area and rub until the stain disappears, then wipe.
06:11Do not waste time to thoroughly remove the burn marks on the bottom of a saucepan.
06:15Instead, fill it with water and add three tablespoons of salt.
06:20Let it rest overnight so that the salt dissolves the cooking residues
06:24and empty the water from the saucepan in the morning.
06:27This way, it will be much easier to remove all this grease.
06:32Imagine the scene. You are on vacation and your shirt is all wrinkled in your suitcase.
06:36You need it tonight, but the hotel has no iron to iron.
06:40Don't panic. Hang the shirt in the bathroom,
06:43and while you take a hot shower, the heat and humidity will cool your shirt.
06:49OK, it won't be perfect, but it will be much better, and all without any effort.
06:55The football match will start from one moment to the next,
06:58and it turns out that you no longer have a battery suitable for your remote control.
07:02You can use a smaller battery instead, which will easily fit inside.
07:07Now take aluminum foil and cool it.
07:10Place the aluminum ball in the space located on the negative or flat end of the battery.
07:16There you go, you can turn on the TV now.
07:19When your tongs break and the piece of plastic escapes from its hole all the time,
07:24it is certainly a sign that you need a new pair.
07:27But there is a way to extend their lifespan.
07:30Put the piece back in its hole,
07:32and then attach these kind of clamps that you can find on the packed bread.
07:36The clamp will provide enough support for the sandal to stay in place.
07:41You received a package, and the invoice is taped on it.
07:45You managed to detach it from the box, but then how do you take off the tape without tearing the paper?
07:51Grab the two ends of the adhesive tape.
07:54If you pull slowly, the tape will stretch and separate from the paper without tearing it.
08:00Fresh bags are perfect for keeping things dry, but it would be great if they were bigger, wouldn't it?
08:07Take two and turn one of them over.
08:09They can now attach to each other and form a large bag, large enough to protect a keyboard, for example.
08:16No need to carry your keys in your hand during your next jogging,
08:20but they are rather in your pocket.
08:22Take an elastic and wrap it around the pocket inside, so your keys won't fall.
08:29You broke your key in the door.
08:31It's stuck in there.
08:32Great!
08:33Calling a locksmith could cost more than a hundred euros.
08:37For a cheaper and faster solution, try using a hot glue stick.
08:43Heat the end with a lighter, and once it's hot enough to melt,
08:47insert the glue into the lock hole.
08:50The melted glue will enter the available space, covering part of the key.
08:55Once cooled, it will combine and firmly attach to the end of the key,
09:00which you just have to remove.
09:04If you have to siphon liquid through a pipe and you want to avoid putting it in your mouth,
09:09dip one end in the liquid and hold the other end up with your thumb that closes the top.
09:15Now stir from top to bottom.
09:18This shaking movement will push the liquid up a little more each time.
09:22Once it has reached the top, lower the pipe and let the gravity do the rest.
09:28You forgot your car keys in your locked car.
09:31It's an old model with a mechanical window.
09:34You could take a belt and try to unlock the lock, but it's long and complicated.
09:39Or you can use an adhesive tape.
09:42Make about twenty 60 cm long strips,
09:45stick them on the window, leaving enough room for the tape to catch on the bottom.
09:51Then, with a friend, take the ends of the adhesive tape and, by holding them together,
09:56pull the big tape down.
09:58The force exerted will allow the window to lower sufficiently so that you can unlock the door.
10:05You've probably heard of these miraculous laundry tips
10:09supposed to make your clothes super clean and like new.
10:12What if these laundry tips were just myths?
10:15Here are three.
10:17Shirts must be buttoned when you put them in your machine.
10:20Is that true?
10:22It's a myth.
10:23It's better to keep the zipper closed so that their teeth don't stick to the fabric of your other clothes.
10:28But buttoning a shirt button can dilate the buttonholes.
10:32In the long run, the buttons will start to slip and your shirt will be easy to throw away.
10:38Washing your clothes in hot water is the best way to clean them.
10:42Is it a myth or a reality?
10:44It's still a myth.
10:46You want to get rid of microbes in your clothes.
10:48However, hot water alone won't be enough.
10:51Nowadays, many detergents are perfectly capable of cleaning your clothes in cold or warm water.
10:58You have to clean the stains on the outside of the fabric.
11:01Is that true?
11:03Most people apply water and soap directly to the stain, starting with the outside of the fabric.
11:09But that's not the best solution.
11:11It's better to start with the inside.
11:14The stain can sink deeper if you treat it from the outside.
11:18Try to bring the stain up to the surface rather than pushing it inwards.
11:24Listening to music is effective in learning a new language.
11:27Is that a myth or a reality?
11:29It's a reality.
11:31Scientists have declared that listening to a song and humming at the same time can help us learn a language.
11:37Many people have trouble learning grammar rules.
11:41However, in our daily lives, we don't always follow them.
11:45Songs can help us memorize common expressions.
11:49Scientists have also claimed that music allows us to remember new words and enrich our vocabulary.
11:55Let me give you an example.
11:57Do you remember your first year of school?
11:59Yes, the alphabet song.
12:02Are you a morning person or a night bird?
12:05In any case, you have to be aware of the realities and myths about sleep.
12:11A person managed to stay awake for 11 consecutive days.
12:14Do you think it's possible or is it an urban legend?
12:18It's a reality.
12:20Randy Gardner set the longest sleep time record.
12:23It was a scientific experiment conducted by Dr. William C. Demond,
12:28who studied sleep at Stanford University.
12:31This doctor recorded and monitored Randy Gardner's sleep activity.
12:36Gardner managed to stay awake for 11 days and 25 minutes.
12:40Your body ends up getting used to less sleep.
12:43Myth or reality?
12:45It's a myth.
12:46Many studies show that your body, and your brain in particular,
12:50can't get used to less sleep.
12:52Did you notice that after a few sleepless nights,
12:55you started to feel more tired during the day?
12:58It's your body that tries to adapt to its lack of rest.
13:01Long-term lack of sleep affects your performance,
13:04your concentration, and your decision-making during the day.
13:09Many adults only need 5 hours of sleep, or even less.
13:13Is it true?
13:14It's very easy.
13:16It's a myth.
13:17National Sleep Foundation experts recommend that adults
13:21sleep between 7 and 9 hours a night.
13:23Some people have a genetic mutation
13:26that allows them to fully wake up after a short night of sleep.
13:30But these people are exceptional.
13:32One in four million.
13:35Some people say they can sleep anywhere,
13:37or at any time,
13:39that they are good sleepers.
13:41What do you think?
13:42Myth or reality?
13:43It's a myth.
13:44A good sleeper sleeps enough, and at regular hours.
13:48Cats spend two-thirds of their lives sleeping.
13:51Is it true?
13:52You probably won't be surprised.
13:54It's a reality.
13:56So, did you manage to answer most of these questions correctly?
14:01How many hidden functions are there in your car
14:04that you've never heard of?
14:06Nowadays, most cars have a color code under their hood.
14:10So it's much easier to know what to look out for
14:13between two inspections.
14:15Like the gauge, the oil cap, or the cooling liquid.
14:19You can even take a look at the brake fluid and the windshield washer fluid.
14:23For everything that is black or gray,
14:25you have to leave it to the mechanics.
14:28Have you ever seen a snowflake-shaped light
14:30on the dashboard of your car?
14:32It's not there to warn you about the arrival of winter holidays,
14:35if that's what you think.
14:37It's actually a sensor that indicates the outside ambient temperature.
14:41It turns on and shows you the indicator
14:43when there is a danger to the road
14:45due to a sudden drop in temperature.
14:49Sometimes, a sound warning or a message on your dashboard
14:53warns you that the roads may be covered in ice
14:56so that you can adjust your speed
14:58or change tires if necessary.
15:02Most cars are also equipped with special devices for the summer,
15:06like sunshades.
15:08Yours may have an additional bonus
15:10that you may want to discover.
15:12We all know that they rotate
15:14to help the driver even when the sun is not shining.
15:17But some of them can also deploy
15:19so that they can provide shade to a larger area.
15:23If you see that yours is not extendable,
15:25there is a simple solution.
15:27Buy a sunshade extender.
15:29You can even find one online.
15:31It attaches to your sunshade
15:33or to your existing windows
15:35to provide better protection against the sun
15:37and better visibility.
15:39Let's discover some hidden features at home.
15:42It's not a witchcraft,
15:44but there is a bad way to make ice in the freezer.
15:47And that's because you're probably not using the ice cream maker properly.
15:52They have this particular shape
15:54because you have to fill the jars
15:56until there is a layer of water on top.
15:59This layer allows you to quickly extract the ice cream from the jar
16:02because it breaks when you twist it
16:04and lets out each ice cream.
16:06You can then catch them in a blink of an eye
16:08and taste your drink.
16:11If you find that the heat in your oven is too high
16:14or if you have to cook in difficult places
16:16that require better temperature control,
16:18there is an easy way to adjust it.
16:22The buttons on your oven
16:24must be equipped with calibrating screws at the back.
16:27Remove the plastic button
16:29and adjust it according to your preferences.
16:31Make sure to unplug the oven from any power source
16:34before doing so.
16:36Do you know what your cook and your car have in common?
16:39They both have a hood that you can open
16:42if you need to take a look
16:44or if they need to be cleaned.
16:46If you look closely at the top of your cook,
16:49you will see two hinges
16:51located at the level of the rear edges.
16:53You can easily lift them up
16:55and clean all the dirt that was stuck inside.
16:58Have you ever wondered
17:00why the glue does not stick inside the bottle?
17:03The answer is a little more complex
17:05depending on the type of glue,
17:07but the simple answer
17:09is that there is no air inside.
17:13PVA glue contains molecules
17:15called polymers and water.
17:17When the glue comes out,
17:19the water evaporates,
17:21leaving behind only the adhesive polymers.
17:23The situation is more or less the opposite
17:25with superglue.
17:27It contains a chemical product
17:29that solidifies as soon as it comes in contact
17:31with the water vapors in the air.
17:34Did you know that Microsoft Word
17:36has a function that you can use
17:38for references and bibliography?
17:40This function is not only useful
17:42to keep a track of everything,
17:44but it also automatically
17:46gives you the corresponding information.
17:48If you like to surround yourself
17:50with lots of plants inside,
17:52here is a simple way to know
17:54if they need to be watered.
17:56Put your finger in the ground.
17:58This should give you a better idea
18:00than just looking at the surface of the plant.
18:02If you can penetrate
18:045 to 7 cm into the ground
18:06and you feel that it is dry,
18:08the plant probably needs to be hydrated.
18:10On the other hand,
18:12this trick works better
18:14if the depth is more limited.
18:16In any case,
18:18it is always preferable
18:20to look for the needs of the plant
18:22in terms of watering and sunlight
18:24before engaging in a project
18:26and always be careful
18:28not to damage its roots.
