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.
