00:00:00 If you have trouble opening a container or a jar, don't make too much effort.

00:00:05 Put the lid under hot water for half a minute, then dry it to be able to hold it well.

00:00:10 And you'll see that it will open like magic.

00:00:13 If you follow a recipe that requires both garlic and onions, add the onions first.

00:00:19 When they become almost translucent, this is the ideal time to add your garlic.

00:00:23 Garlic cooks faster than onions.

00:00:25 Therefore, if you put these two foods in the same pan, the garlic will burn and your dish won't be very good.

00:00:32 Do you like avocados?

00:00:34 Here's how you can easily check if they are ripe or not.

00:00:37 Take a look at the tail of the fruit.

00:00:39 If it comes off easily, it means the avocado is good to eat.

00:00:43 If it doesn't, you'd better wait a few more days because it's not ripe yet.

00:00:48 Here's how you can know if an egg is fresh or not.

00:00:52 Break it and check the yolk.

00:00:55 If you see that it's surrounded by a white circle and that it's well in the middle, your egg is fresh.

00:01:00 The yolk of an egg is also supposed to be voluminous.

00:01:03 If it's flat, it's better not to eat the egg.

00:01:06 If you see that the white part has no clear outline and that your egg is spreading,

00:01:10 there's a good chance that it's broken.

00:01:13 To evaluate the quality of your eggs, place a raw egg in its shell in a bowl of water.

00:01:18 If the egg stays at the bottom, it's good.

00:01:20 If one of its sides is close to the surface of the water, your egg is not fresh, but you can still eat it.

00:01:25 But if it floats, it shouldn't be eaten.

00:01:28 Don't brush your teeth in the morning and in the evening in the same way.

00:01:33 It's important to brush your teeth in the morning, but especially to get a fresh breath.

00:01:37 In the evening, you should brush your teeth more carefully.

00:01:40 You'll prevent bacteria from proliferating and protect your gums and teeth.

00:01:45 Speaking of bad breath, here's a good tip to get rid of it in a blink of an eye.

00:01:50 Cucumber slices.

00:01:52 If you don't have a pastry knife at hand, you just need to eat a slice of cucumber to solve this problem.

00:01:58 When you buy natural peanut butter, keep it upside down.

00:02:03 This way, it will remain very homogeneous.

00:02:06 In addition, its oil will go up, which will make your peanut butter easier to mix.

00:02:13 When you put something down for a moment, say it out loud.

00:02:16 For example, I put my phone down next to my bed.

00:02:20 This way, you'll mobilize several parts of your brain, including those responsible for speech, and you'll remember it better.

00:02:27 You can do the same thing when, for example, you blow a candle.

00:02:31 Disconnect your fan, turn off your kitchen, or take your keys, your wallet, and other objects when you leave your house.

00:02:38 End these little moments of doubt when you wonder if you haven't forgotten anything.

00:02:43 If you visit a friend and you bring something you don't want to forget on your way out, put it next to the keys to your car.

00:02:51 It's impossible to leave without it.

00:02:53 If you have trouble making a decision, play head-to-head.

00:02:57 It's not really about letting the piece decide for you.

00:03:01 But while you wait to see the result, your mind will automatically think of the result you really want, but which remains unconscious or unexpressed.

00:03:10 You're at the supermarket and you want to know if a certain pumpkin is good or bad.

00:03:16 Hit it. Do you feel like it's empty inside?

00:03:19 That's a good sign. As for the outside, it must be hard.

00:03:23 We sometimes throw in foods that are still good, like yogurt, which has stratified.

00:03:29 You know that layer of liquid on top? It's milk, and it contains nutrients.

00:03:34 Mix your yogurt to make it homogeneous. You can still eat it.

00:03:38 When you buy chicken, make sure there's no liquid around.

00:03:43 For example, if you take the chicken out of the freezer and you see a lot of ice all around, it's better not to eat it.

00:03:50 You move into a new apartment or a new house?

00:03:53 Start by moving your bedroom.

00:03:55 Buy a bed first. When you're tired of moving and cleaning, you'll want a comfortable place to rest.

00:04:04 Here's a tip that will help you determine if your coconut oil is frothed.

00:04:09 Leave it in the fridge for half an hour.

00:04:11 Coconut oil becomes solid at low temperature.

00:04:14 The frothed oils disintegrate and take on a separate layer.

00:04:20 To know if an onion is frothed, just look at what's under the first layer of froth.

00:04:25 You see spots, and the froth is discolored. It's froth.

00:04:30 Choose another one and peel it well if you only have one.

00:04:33 It's possible to determine with the naked eye whether a lemon is ripe or not.

00:04:38 If its skin is smooth and has a yellow base, it's ripe.

00:04:41 A greenish hue and pale yellow indicate that it's not ready to be consumed.

00:04:48 If you want to fully enjoy your coffee, it's better to buy seeds and mold them yourself.

00:04:53 Or ask the seller to do it in the store where you buy your coffee.

00:04:57 It's the best way to make sure that the product doesn't contain any of the additives that can be found in an ordinary coffee.

00:05:04 If you're looking for a simple way to separate the yolks from the whites, try this.

00:05:08 Take a clean, empty plastic bottle.

00:05:11 Break an egg into a bowl, squeeze the bottle over the yolk and slowly release it.

00:05:16 You'll create a hole that will slide the egg yolk into the bottle.

00:05:20 And there you go, the yolk and the white are separated.

00:05:23 And it's easy.

00:05:24 Imagine that you've lost an earring or another small object in the house.

00:05:29 Your vacuum cleaner can help you, but don't forget to use a bath.

00:05:33 This way, the object won't get mixed up with the dust and dirt that's in the bag.

00:05:38 You want to take your favorite lotion on a trip, but it takes up too much space?

00:05:42 You can use a contact lens case.

00:05:45 It's not very bulky and it's a perfect solution for short-term trips.

00:05:50 A hair straightener is an amazingly effective tool for brushing your hair.

00:05:55 Especially if you're not a fan of the classic way of brushing your hair.

00:05:59 To know if a battery is still working, drop it 15 cm above a table.

00:06:05 If it bounces once and falls, it means it's in good condition.

00:06:09 If it bounces more, it means it's worn or on the point of being.

00:06:14 If your razor doesn't have a cap, you can use a drawing pin to cover its blade

00:06:19 and to protect the rest of your stuff if you wrap it with fragile objects or materials.

00:06:25 You can easily differentiate your keys with nail polish, especially if they all look the same.

00:06:31 You won't have to try them all before you find the right one.

00:06:35 When you heat something in the microwave, make a circle in the middle of your dish.

00:06:40 This way, your food will warm up more evenly.

00:06:44 A straw is a nice tool to cut strawberries, don't you think?

00:06:49 A muffin pan is very useful if you want to serve different condiments for your barbecue.

00:06:55 It will also save you time when you're doing the dishes.

00:06:59 You may have noticed the stripes on some types of chips.

00:07:03 Well, on the one hand, they make it easier to distribute spices and seasonings.

00:07:08 On the other hand, the substances that give your chips a cheese flavor are mainly stored inside these stripes.

00:07:15 And on the other hand, the stripes also make the chips more crispy.

00:07:20 Some cars have a small coffee cup-shaped indicator on their dashboard.

00:07:25 It's the vehicle's anti-sleeping mechanism.

00:07:28 Some manufacturers equip their cars with a sleep detection system.

00:07:34 This system analyzes the speed, the angle of the wheels, and the deviations in the trajectory

00:07:38 to detect when it's time for the driver to take a break.

00:07:41 If this is the case, the vehicle emits several sound signals

00:07:45 and the coffee cup-shaped indicator starts blinking.

00:07:48 Some plastic milk bottles have recesses on the sides.

00:07:53 They have several functions.

00:07:55 On the one hand, when the milk is turning,

00:07:57 this process usually leads to inflation and an increase in the pressure inside the bottle.

00:08:03 This is when the inflation becomes useful

00:08:06 because it accuses the pressure and time preventing the bottle from exploding.

00:08:10 In addition, if you decide to freeze the milk, it will spread like any other liquid.

00:08:16 And again, it's the inflation that will change

00:08:19 and prevent the bottle from bursting inside your freezer.

00:08:23 You may be wondering why Jerrycans have three handles.

00:08:28 This is a clever idea from the designer.

00:08:30 If you carry the bottle alone,

00:08:33 you can use only the central handle to distribute the weight evenly.

00:08:38 But if your friend wants to help you, each of you can grab the side handle.

00:08:43 Did you know that the first jeans had a problem?

00:08:47 Indeed, the workers and miners who were the first to wear jeans

00:08:52 were putting too much pressure on this poor fabric.

00:08:55 As a result, the seams did not resist the tension and tore.

00:09:00 To avoid this, tiny metal nails were invented.

00:09:04 The self-adhesive notes come off relatively easily

00:09:08 because the adhesive is evenly distributed on the paper

00:09:11 in the form of small drops.

00:09:13 Only some of these drops touch the surface of the object on which you stuck the note.

00:09:19 Which explains why, when you take off a post-it and stick it on something else,

00:09:24 it continues to stick.

00:09:26 And this until all the glue is used or covered with dirt.

00:09:30 Soda bottles are always filled in such a way

00:09:34 that there is still a space between the liquid and the cap.

00:09:37 And this is due to the fact that soda contains carbon dioxide.

00:09:40 It is a gas that can spread when the bottle is heated.

00:09:43 If there was no space in the bottle,

00:09:45 it could burst under the effect of the pressure exerted inside.

00:09:50 In addition, by opening your drink, the gases escape in the form of bubbles.

00:09:54 And, without this space, it could overflow.

00:09:57 The space provided also allows to solve this problem.

00:10:01 The dental floss is very useful for teeth,

00:10:04 but it can be difficult to use

00:10:07 because it regularly slips from the fingers and gets tangled.

00:10:10 To avoid these problems, cut a piece of dental floss

00:10:13 and tie these two ends together.

00:10:15 It will be much easier to use and will not hurt your fingers.

00:10:20 Let's take a look at these horizontal lines on plastic bottles.

00:10:24 These allow the bottles to maintain their shape.

00:10:27 Some bottles are made with flexible plastic.

00:10:30 Without these lines, these bottles would not be able to maintain their shape over time

00:10:36 and would easily twist or even break.

00:10:39 The round and flexible part located under the capsule of a soda bottle

00:10:44 prevents the gases from escaping.

00:10:46 Without it, your soda bottle would become flat in no time,

00:10:50 probably even before you bought it.

00:10:53 If you do not have a place to put your dental floss after using it,

00:10:58 cut its flat end at the level of the first groove and place it on the table.

00:11:02 This allows you to rest the used part of your dental floss on the grooved part

00:11:07 so that it does not touch the table.

00:11:09 You can also make a fortune support for disposable chopsticks.

00:11:14 These have an extra piece at the end.

00:11:17 Break this piece before separating the chopsticks.

00:11:20 When you want to take a break,

00:11:22 you just have to simply place the chopstick on this "support".

00:11:26 Donuts have the shape of a ring because, without the hole in the middle,

00:11:31 they may be overcooked on the edges, but not cooked and sticky inside.

00:11:36 With a hole in the center, the outside and the inside are cooked and ready to be consumed at the same time.

00:11:44 Have you ever noticed this layer of transparent liquid in gel-based pencils?

00:11:49 This is what is called the "ink follower".

00:11:52 The gel in these pencils contains pigment particles dissolved in a polymer solution.

00:11:57 The gel must be thick enough to hold the pigment particles in suspension,

00:12:02 but also thin enough to flow first on the ball, then on the paper.

00:12:06 The main task of the liquid is to create a barrier to prevent the gel from evaporating or flowing.

00:12:12 Without this transparent fluid, your gel-based pencil would not work.

00:12:16 The liquid remains in the same position and does not dissolve with the gel.

00:12:20 It does not move backwards and does not flow from the pencil.

00:12:24 Some buttoned shirts have a hidden button behind the collar.

00:12:29 It is mainly used to prevent the tie from overflowing.

00:12:32 As for the small loop in the back,

00:12:34 it allows you to suspend the shirt with a hook to prevent it from freezing.

00:12:40 The rings, at the extreme of the zipper,

00:12:43 especially when two cursors are used together,

00:12:46 exist so that you can tie them together with a lock

00:12:50 and keep your hands too curious apart.

00:12:53 Most ambulances have this word, "Ecnalabma", printed on the hood of the vehicle.

00:12:59 It is the word "ambulance" backwards.

00:13:01 It is written backwards so that the driver who precedes the ambulance

00:13:04 can read the word correctly in his rearview mirror.

00:13:07 He can then move away and let the ambulance pass.

00:13:10 The mechanical stair brush plays an important role in terms of safety.

00:13:15 You may have heard that most accidents occur

00:13:18 when people stuck their bags or clothes in the mechanical stairs

00:13:22 because they are too close to the walls.

00:13:25 Thanks to these nylon brushes on both sides,

00:13:28 you can only do otherwise than move your feet away from the side walls of the mechanical stairs.

00:13:33 Result, the accidents are over.

00:13:37 The side holes of the baskets are there to tie them.

00:13:40 The baskets, which were originally invented for basketball players,

00:13:44 this elaborate design allowed them to adapt to the feet of any player.

00:13:49 It was enough to tie their baskets to their convenience.

00:13:53 The holes located at the base of your headphones

00:13:56 allow the air to circulate upwards and through the speakers.

00:14:00 This increases the bass frequencies and makes the low sounds deeper.

00:14:05 The sound quality is also improved.

00:14:08 Have you ever found yourself with a jar of apple compote without a spoon at hand?

00:14:13 Yet each snack packet is already equipped with an integrated spoon.

00:14:16 Just turn and twist the lid several times in aluminum foil.

00:14:21 And the trick is done.

00:14:23 This loop with the small slots on the front of the backpacks

00:14:27 was originally reserved for backpackers.

00:14:30 The slots were used to transport ropes.

00:14:33 Today, we find these slots on almost all backpacks.

00:14:37 Why not use them to transport a gourd, an umbrella or a pair of sneakers?

00:14:42 The markers are filled with a special translucent fluorescent ink

00:14:47 that can shine in the dark.

00:14:49 Yellow and light green colors are the most popular

00:14:51 because they do not prevent you from seeing the text after a photocopy in black and white.

00:14:55 Photocopiers perceive yellow and light green marks as almost non-existent

00:15:00 and do not print them too much.

00:15:02 The stop sign has an octagonal shape

00:15:05 to help drivers easily recognize it, even if they see it from behind.

00:15:09 At the time when the signs were not yet reflective,

00:15:13 this shape allowed drivers not to confuse the stop sign with any other at night.

00:15:19 The number 57 on the bottle of Heinz ketchup has nothing to do with the product.

00:15:24 It turns out that the place where the numbers are

00:15:27 is the most effective point to make the ketchup flow.

00:15:30 So, stop hitting the bottom of your bottle of sauce and press the 57.

00:15:36 Many houses have triangular-shaped roofs.

00:15:40 This allows rain, snow and dead leaves to slide along the slope.

00:15:45 If all this accumulated on your house, your roof would eventually give in.

00:15:50 The round shape of the plane's windows represents an essential security measure.

00:15:55 It avoids plane accidents.

00:15:58 The weak points are generally located in the corners.

00:16:01 In other words, if the plane's windows were square or rectangular,

00:16:05 each window would have four weak potential points.

00:16:08 Under pressure, they would risk bursting.

00:16:11 Are the letters SSSS on your boarding pass a reason to worry?

00:16:17 What is much more dangerous than turbulence?

00:16:20 Should you try to be the first to get on the plane?

00:16:23 You are about to find out.

00:16:26 You may have noticed that most planes have blue seats.

00:16:30 There is no mystery.

00:16:32 Airlines choose this color because it is considered to have a calming effect.

00:16:37 This color is supposed to make passengers feel comfortable

00:16:40 and even help the most nervous passengers to relax.

00:16:43 But there is also another more practical reason.

00:16:46 The spots, dirt and traces are less visible on a dark blue fabric.

00:16:52 Never throw your boarding pass in a public place.

00:16:55 It contains tons of sensitive information about you,

00:16:58 including your name and your frequent passenger number.

00:17:01 This information can allow someone else to check your future reservations,

00:17:05 change your seat, or even cancel your flights.

00:17:08 The best way to manage a boarding pass of a flight you have already taken

00:17:13 is to take it home and put it in a paper grinder.

00:17:16 By the way, if you see the letters SSSS on your boarding pass,

00:17:21 prepare for additional security checks.

00:17:24 Instead of these letters, there may be a damaged pattern.

00:17:27 Whatever it is, if you have one of these marks,

00:17:30 your luggage can also undergo a thorough inspection.

00:17:33 But why could they choose you for a secondary check?

00:17:37 Some of these criteria are to make a reservation for a simple trip

00:17:40 or to pay your ticket in cash.

00:17:42 In some cases, the selection is also totally random.

00:17:46 Look, your door is open and the boarding has begun.

00:17:49 Wait, where are you going in a hurry?

00:17:52 The trick of experienced globetrotters is to always board last.

00:17:56 First, you don't waste time queuing.

00:17:59 Then, there are fewer people on the platform and in the aisle.

00:18:02 And you finally spend less time on the plane.

00:18:05 Anyway, no one will take your seat, you know.

00:18:08 This boarding pass is a little bit like a "suitcase".

00:18:11 It is a little bit like a "suitcase"

00:18:14 However, there is an exception.

00:18:17 If you have a bulky luggage, it can be more judicious not to board last.

00:18:21 Otherwise, there is a good chance that the whole luggage compartment

00:18:24 will be occupied before you arrive at your seat.

00:18:27 Your luggage could then be found in another part of the plane

00:18:31 and you will have to wait for the other passengers to land before you can pick it up.

00:18:35 Flute!

00:18:37 Before take-off and landing,

00:18:39 the boarding agents usually operate a small switch on the door of the toilets.

00:18:43 This prevents it from opening when it is not supposed to.

00:18:46 With the same ease, a boarding agent can open the door

00:18:49 when someone is inside.

00:18:51 Just lift the toilet panel and put the handle in the unlocked position.

00:18:55 Pilots don't really care about turbulence.

00:19:00 It is because they know that there is something much more dangerous than any turbulence.

00:19:04 The ascending currents.

00:19:06 In most cases, the turbulence makes you fall only a few meters.

00:19:10 Even if you feel like you are falling from the Empire State Building.

00:19:14 If the turbulence is strong enough for the pilots to ask the air hostesses to sit down,

00:19:19 the plane can go down from 3 to 6 meters.

00:19:22 But in fact, the most extreme and violent turbulence are very rare.

00:19:26 An ascending current is a large mass of air,

00:19:29 part of a storm or another meteorological phenomenon that moves upwards.

00:19:34 However, pilots do not see the ascending currents on their radar at night.

00:19:37 And when a plane meets one, it is as if it was flying over a huge dodan at 800 km/h.

00:19:42 An ascending current is also extremely dangerous,

00:19:46 because it can push a plane up to dangerous altitudes.

00:19:49 Modern planes are equipped with a special system

00:19:55 that detects other planes, mountains and different solid objects on their trajectory.

00:20:00 At 16 km from another plane and once in the cockpit,

00:20:03 it starts repeating "traffic, traffic".

00:20:06 8 more km and the same way starts giving instructions to the pilots.

00:20:10 Planes can operate with a single engine, even during take-off and landing.

00:20:17 A simultaneous failure of the two engines is almost impossible to imagine.

00:20:21 But in this case, a plane would not fall from the sky like a stone.

00:20:25 The pilots would have up to 20 minutes to find a suitable place to land.

00:20:29 The way the cabin is pressurized has a significant effect on your taste buds.

00:20:34 You lose up to 30% of your ability to taste sweet and salty things.

00:20:38 In other words, it's not that the food served on the planes is not tasty,

00:20:43 but you don't taste their flavor.

00:20:45 It is also the main reason why catering companies,

00:20:48 airlines, add salt and spices to the dishes they prepare.

00:20:51 But do you know what could help you?

00:20:54 Soundproof headphones.

00:20:56 For a mysterious reason, which probably has a scientific explanation,

00:21:00 cutting all the ambient noise can help your taste buds.

00:21:04 Each of these "ding" you hear during the flight also has its own meaning.

00:21:08 In most airlines, a "boom" shortly after take-off

00:21:11 indicates that the landing gear is retracting.

00:21:14 Three consecutive "ding" means that there is more emergency than one.

00:21:18 A high-pitched sound informs the crew members

00:21:21 that their colleagues need them in another part of the plane.

00:21:24 Three low-pitched sounds mean that there is serious turbulence to come.

00:21:29 The crew members are supposed to put the food trucks away,

00:21:32 take their seats and fasten their seatbelts.

00:21:34 If you are a nervous passenger, choose a seat in the middle of the cabin.

00:21:39 Turbulence mainly affects the front and rear parts of the cabin.

00:21:43 The central part, which is above the wings, does not shake as much.

00:21:47 The pilots and co-pilots take different meals.

00:21:51 The reason for this precaution is very simple.

00:21:53 Imagine that the two pilots eat the same dish

00:21:55 and that they have a food poisoning.

00:21:58 In this case, neither of them will be able to control the plane.

00:22:01 If they still want to have the same dish

00:22:04 and do not want to accept to take something else,

00:22:06 there is a safety net.

00:22:08 The pilots do not take their meal at the same time.

00:22:11 If a pilot has eaten the dish and still feels well several hours later,

00:22:15 the other pilot can also take his meal.

00:22:17 What would you say if you were asked

00:22:21 what is the most disgusting place in an airplane?

00:22:23 No, it is not the toilet seat.

00:22:25 It is not even in the toilets.

00:22:28 Air traffic controllers recommend

00:22:29 to pay particular attention to the headrests,

00:22:31 the seat covers, the tablets and the seat belts.

00:22:34 Experiments have shown that one third of all seat belts

00:22:38 are covered with fungi and mold.

00:22:41 Most tablets are covered with bacteria.

00:22:43 The seat covers are also very dirty.

00:22:46 But the headrests are the dirtiest of all.

00:22:49 In most cases, the flight attendants do not have time to change them

00:22:53 or disinfect them between flights.

00:22:55 What is the flight attendant's job?

00:22:57 If the flight attendant announces

00:23:01 that he is finishing administrative formalities,

00:23:04 it means that he is busy revising the flight itinerary

00:23:07 or waiting for the ground staff to prepare the flight book.

00:23:09 This is a journal that contains the official report of a trip.

00:23:12 Some planes, especially long-haul aircraft,

00:23:16 have secret rooms where crew members can rest.

00:23:19 These rooms, called crew rest compartments,

00:23:23 are located at the back of the aircraft or behind the cockpit.

00:23:26 Such a compartment can hold up to 10 comfortable beds

00:23:30 where the flight attendants can rest.

00:23:32 The aircraft's windows are made of super-resistant plexiglass

00:23:37 that can easily withstand high speeds.

00:23:39 The windows have a special shape,

00:23:41 so that the high pressure inside the cabin

00:23:43 pushes them against the fuselage of the aircraft.

00:23:45 In other words, the aircraft's windows

00:23:49 are very unlikely to break.

00:23:52 In the past, the aircraft's windows were square,

00:23:55 but the pressure accumulated in the corners of these windows,

00:23:58 which made them weak points par excellence.

00:24:00 This means that each square window had four weak points.

00:24:04 They were therefore likely to crush

00:24:07 under the enormous pressure of high altitudes.

00:24:09 Fortunately, the design of curved aircraft windows

00:24:13 solved this problem once and for all.

00:24:15 This shape distributes the pressure

00:24:17 and reduces the probability of cracks or any other damage.

00:24:21 Aircraft are regularly hit by lightning,

00:24:23 at least once a year or once every 1,000 hours of flight.

00:24:26 Nowadays, this is totally safe.

00:24:30 Electric charge simply crosses the aircraft's aluminum hull.

00:24:34 It does not cause any damage to the aircraft.

00:24:36 But did you know that aircraft are not only hit by lightning,

00:24:41 but that they also trigger it?

00:24:43 When an aircraft crosses a cloud,

00:24:47 the friction between its fuselage and the air

00:24:50 creates static electricity.

00:24:52 And sometimes, it can cause lightning.

00:24:54 Barely two decades ago,

00:24:58 no one could have imagined that a key

00:25:00 containing hundreds of gigabytes

00:25:02 could hold in our pocket.

00:25:04 We are now used to transferring files

00:25:07 from one device to another via USB.

00:25:09 In 2000, it was mainly two companies

00:25:12 that developed and sold the first USB 1.0 keys.

00:25:15 They quickly became USB 2.0, 3.0, Type C, and so on.

00:25:19 They are very durable,

00:25:21 especially when properly protected.

00:25:23 The design of these devices is almost perfect.

00:25:27 So perfect that you always insert them in the wrong direction.

00:25:30 I admit it!

00:25:31 The two square holes are there to hold the key

00:25:34 when it is inserted into its port.

00:25:36 It does not completely get stuck, but it holds.

00:25:41 You can protect your USB key with an adapted encryption.

00:25:44 If someone steals it, they will not be able to read it.

00:25:47 Encrypted files will turn into an incomprehensible mixture

00:25:50 of letters and numbers that no one will be able to decipher.

00:25:54 This only works in the event of a USB key theft.

00:25:57 If you use online services like messaging or emails,

00:26:00 encryption is not enough.

00:26:02 It is certain that your interlocutor will not be able to read your files,

00:26:05 but it is certain that your key will be able to read them.

00:26:08 This is when the encryption from end to end comes into play.

00:26:11 This means that all incoming and outgoing information

00:26:14 is once again transformed into a mess

00:26:17 for all those who participate in the exchange, including hosts.

00:26:20 Online storage has revolutionized the world.

00:26:24 You can now save everything that is on your desk on the Internet

00:26:28 and access these files from several devices.

00:26:31 Everything you have saved is now in your inbox.

00:26:34 All you need is an email address and a password,

00:26:38 and poof, you are saved and you can keep all your files in the same place.

00:26:42 It is not about data floating in the clouds,

00:26:45 but simply servers that physically store data.

00:26:48 They look like simple computers,

00:26:51 but without the screen for display.

00:26:54 Serving these servers is very expensive.

00:26:57 This is why you usually have to pay for their services.

00:27:00 They are full of data,

00:27:02 and they are managed by third-party companies.

00:27:05 It is like remote access to a computer.

00:27:08 Servers are made up of a master server,

00:27:11 a backup server,

00:27:13 and several connected servers that ensure the quality of the service.

00:27:16 The more you pay,

00:27:18 the better the server that manages your data will be.

00:27:21 In the world of computers,

00:27:24 it is impossible to permanently erase something.

00:27:27 Any file you have stored in a computer

00:27:30 is stored in the hard drive

00:27:33 as an electrical impulse.

00:27:36 Depending on your device,

00:27:39 the file will be moved to a new folder.

00:27:42 This does not mean that it no longer exists,

00:27:45 but that it has been moved to a different folder

00:27:48 and that you can easily retrieve it.

00:27:51 So if you are afraid of erasing an essential file

00:27:54 that you have been working on for weeks,

00:27:57 you can totally erase it.

00:28:00 But if your device breaks down,

00:28:03 the data is lost.

00:28:06 If you have a device that works with Windows 10,

00:28:09 you probably turn off your computer

00:28:12 thinking it is completely disabled.

00:28:15 This is not the case.

00:28:18 Windows 10 does not completely shut down,

00:28:21 but it is hibernating.

00:28:24 The Windows operating system is known to be easy to use.

00:28:27 All commands are immediately visible.

00:28:30 But computer magicians know

00:28:33 that all you have to do is type "cmd" in the search bar

00:28:36 to open the command prompt.

00:28:39 It looks like a random character character,

00:28:42 but this is where you can do a lot of things with your device.

00:28:45 If you don't like the black window,

00:28:48 you can always choose a color of your choice.

00:28:51 To launch a command, right-click on the title bar

00:28:54 and then click on "Properties".

00:28:57 Another window will open,

00:29:00 on which you will see the option of the color choice.

00:29:03 You can choose any color for the background and for the text,

00:29:06 and you can adjust the opacity of the window.

00:29:09 That's easy.

00:29:12 It's more complicated when you want to type commands.

00:29:15 If you want to consult all the drivers present on your Windows 10 computer,

00:29:18 you can do it in the spaces.

00:29:21 The list of your drivers will appear on your screen like magic.

00:29:24 It's a good way to quickly solve problems

00:29:27 instead of manually searching for them.

00:29:30 You can also hide certain files in your computer

00:29:33 by using the command prompt and typing

00:29:36 "@+h+s+r folder_name"

00:29:39 before typing on "Enter".

00:29:42 You insert the file name you want to hide

00:29:45 and... poof! It disappears.

00:29:48 There is a less professional way to do it.

00:29:51 Click on the properties of the file and check the "Hide" box.

00:29:54 It's a quick technique to hide your files,

00:29:57 but not very effective.

00:30:00 If you click on "Hide hidden files", everything will be visible again.

00:30:03 The command prompt is not only used to work.

00:30:06 You can also play games on it to pass the time.

00:30:09 Don't expect an ultra-realistic AAA game

00:30:12 with epic gameplay.

00:30:15 Type this command and you'll be in a role-playing game

00:30:18 based on text in which you can create a character

00:30:21 and move around in its world.

00:30:24 Google Chrome is one of the most famous search engines.

00:30:27 You can also play a game there, like in the command prompt.

00:30:30 Click on "Ctrl+Mage+J"

00:30:33 to open the console.

00:30:36 Then type "text-adventure" in the search bar.

00:30:39 Don't panic! You just opened a sort of

00:30:42 back-end of the page.

00:30:45 Click on "Console".

00:30:48 A text will appear asking you if you want to play a game.

00:30:51 Click on "Yes" and here you go!

00:30:54 You will receive basic information on the basic commands

00:30:57 and an introduction to the adventure.

00:31:00 If you want to play something more contemporary,

00:31:03 you can play alone.

00:31:06 Type "Solitaire" in the search bar and here you go!

00:31:09 You can then give yourself a lonely ride

00:31:12 on your search engine.

00:31:15 And if you get bored, you can play Pac-Man, a classic.

00:31:18 If you are part of the 3310 generation,

00:31:21 this game will remind you of your childhood.

00:31:24 Type "Snake" in Google and here you go!

00:31:27 When the Internet doesn't work,

00:31:30 you can play with the dinosaurs in your search engine

00:31:33 while you wait for your Wi-Fi to come back.

00:31:36 It's a super simple game.

00:31:39 After pressing "Enter", you just have to press the space bar

00:31:42 to avoid obstacles. After a while,

00:31:45 you can also go down. It will complicate things.

00:31:48 And here you go! You can have fun even without Wi-Fi.

00:31:51 You can pause the game whenever you want

00:31:54 by pressing "Alt" or "F11".

00:31:57 Just click anywhere on the screen to continue playing.

00:32:00 Windows 11 has some very cool hidden features

00:32:03 that are very useful, like for example

00:32:06 the ability to set the volumes of each application separately.

00:32:09 Click on "Settings" and then on "System"

00:32:12 and then click on "Sound".

00:32:15 You will have access to all the volumes as well as the main volume.

00:32:18 The sticky copy is totally essential

00:32:21 to our daily use of the computer.

00:32:24 Windows 11 has taken this function very seriously

00:32:27 and has created "Clipboard History".

00:32:30 This option allows you to save the copied text

00:32:33 in a dedicated location that you can check anytime.

00:32:36 The good news is that it also works on Windows 10.

00:32:39 Press the "Windows + V" keys

00:32:42 and there you go! If you have too many windows open

00:32:45 on Windows 11, you can simply select

00:32:48 the window you are interested in and shake it.

00:32:51 It will reduce all the other windows and there you go!

00:32:54 You can now clean everything.

00:32:57 Be careful, I'm shaking!

00:33:00 Most kitchen scissors have metallic teeth

00:33:03 that look like the middle part of a pair of pliers.

00:33:06 They can help you break nuts, crab shells

00:33:09 and make other tough products.

00:33:12 You can also open jars and bottles

00:33:15 or remove the stems of herbs with the help of the scissors.

00:33:18 You can keep your meals and food fresh

00:33:21 and store them in a plastic bag and leave them in the freezer.

00:33:24 Once the sponge has frozen,

00:33:27 it will stay that way for a long time.

00:33:30 Keep in mind that you must use a waterproof bag and a new sponge.

00:33:33 If you turn a Tupperware,

00:33:36 you will see symbols.

00:33:39 They will tell you if you can put the container in the dishwasher,

00:33:42 if it can go to the microwave or be frozen.

00:33:45 You may even discover how to recycle it.

00:33:48 There are two ways to use the scissors, not just one.

00:33:51 The bottom part of the device has a metal plate

00:33:54 that folds the scissors inwards after you've pierced the paper.

00:33:57 What many people don't know is that you can turn this plate

00:34:00 to switch from normal mode to scissor mode to the outside.

00:34:03 The adjustment to the outside is intended for temporary use.

00:34:06 The scissors fold outwards,

00:34:09 which makes it easier to remove them if necessary

00:34:12 and less damaging to the paper.

00:34:15 When you drink a sip of coffee in a cup

00:34:18 closed by a lid,

00:34:21 the pressure inside the cup decreases.

00:34:24 That's why the air from the outside tries to penetrate the cup.

00:34:27 The tiny lid hole allows the air to penetrate in this way

00:34:30 and the liquid can flow more easily through the main hole.

00:34:33 It is often difficult to determine

00:34:36 the amount of detergent you need

00:34:39 to wash your laundry without overdoing it.

00:34:42 Look at the cap of your product.

00:34:45 It usually has a marker that indicates

00:34:48 the amount of product you need to add to your laundry.

00:34:51 There may also be instructions on the bottle.

00:34:54 It will tell you how to measure the detergent.

00:34:57 You can use most screwdrivers with a wrench

00:35:00 to create more torque.

00:35:03 Simply place the wrench on the handle of the screwdriver.

00:35:06 This way you will need to exert much less force than before.

00:35:09 This will allow you to reach difficult places more easily.

00:35:12 The hole in a ruler can be useful

00:35:15 if you want to hang a device on a hook.

00:35:18 You can also place a pencil tip in this hole

00:35:21 if you need to draw a perfect circle.

00:35:24 Coffee shaker sticks have holes

00:35:27 because they reduce the resistance of your drink.

00:35:30 This way they can stir the sugar much more efficiently.

00:35:33 This design also makes these plastic sticks more solid

00:35:36 and prevents them from twisting in hot water.

00:35:39 And since they are partially hollow,

00:35:42 less plastic is used when they are produced.

00:35:45 Some chocolate boxes have little bumps

00:35:48 between the holes for the candies.

00:35:51 If you press on them, the chocolates around them

00:35:54 come out of their compartments.

00:35:57 The little bumps on the F and J keys on the keyboard

00:36:00 help people find the right keys without looking down.

00:36:03 This is particularly useful for those who use touch sensors.

00:36:06 The rugged bands on the sides of the road

00:36:09 are installed here to warn the drivers

00:36:12 who are getting stuck behind the wheel.

00:36:15 When their tires pass over these bands,

00:36:18 the noise and vibrations work like an alarm.

00:36:21 The black grid of the microwave oven is called a Faraday shield.

00:36:24 It contains the electromagnetic energy inside the oven

00:36:27 and protects the outside from radiation.

00:36:30 The grid also speeds up the cooking process.

00:36:33 The bottles have a long neck so that your drink

00:36:36 stays fresh longer.

00:36:39 By keeping the neck and not the bottle itself,

00:36:42 your drink will not heat up.

00:36:45 The sockets on the surface of a golf ball

00:36:48 increase their length and reduce the resistance of the air.

00:36:51 This means that the ball can go further.

00:36:54 The sockets do not necessarily have to be spherical.

00:36:57 There is a tab at the bottom of your rearview mirror.

00:37:00 If you push it backwards while driving at night,

00:37:03 the headlights of the car you are following will not blind you as much.

00:37:06 If you are driving during the day,

00:37:09 pull the tab forward.

00:37:12 You can peel an orange more efficiently

00:37:15 if you first cut the skin at the top and bottom.

00:37:18 Then make a notch on one side and open the skin by pulling on it.

00:37:21 Headrests and cars are detachable.

00:37:24 You can use them to break the windows

00:37:27 if you are stuck in your vehicle.

00:37:30 But by breaking the window, you can easily get hurt.

00:37:33 So try to slide one of the branches between the window and the door.

00:37:36 Then pull the headrest towards you.

00:37:39 The window will break.

00:37:42 But first try to close the door.

00:37:45 The single goblets used during barbecue parties

00:37:48 can help you measure the liquids.

00:37:51 The first line means 1 ounce.

00:37:54 The second line means you poured 5 ounces.

00:37:57 And the third line means 12 ounces.

00:38:00 Baskets were originally invented for basketball players.

00:38:03 And as they needed to tie their shoes

00:38:06 in the most comfortable way possible,

00:38:09 they invented the holes on the sides.

00:38:12 This allowed the player to tie their basketball as he wished

00:38:15 and adapt to all feet.

00:38:18 The holes were placed here to prevent the seams from tearing.

00:38:21 In the past, it was mainly the miners and other workers

00:38:24 who wore jeans.

00:38:27 That's why this garment had to be particularly resistant.

00:38:30 And even if nowadays jeans are no longer subject to this kind of constraint,

00:38:33 the tradition of the rivets persists.

00:38:36 A large toothed spoon is very useful

00:38:39 to take out the spaghetti from the pan.

00:38:42 And the hole in the middle of this spoon can help you measure the portions.

00:38:45 A portion is equal to as much dry pasta

00:38:48 as you can get into the hole.

00:38:51 Sometimes, rinsing the dish beforehand

00:38:54 can lead to a bad wash.

00:38:57 Special sensors inside modern dishwashers

00:39:00 can detect how dirty your plates are.

00:39:03 Then they send a controlled water jet to wash away all this dirt.

00:39:06 The only thing you're supposed to do

00:39:09 is remove the solid food from your plates

00:39:12 and wash them properly.

00:39:15 Ketchup containers with folds that are given to you

00:39:18 in fast food restaurants can get a little bigger.

00:39:21 Just pull the folds outwards

00:39:24 and your container will contain a lot more sauce.

00:39:27 When you use a suction cup to unclog a kitchen sink or toilet,

00:39:30 make sure you have the right tool.

00:39:33 If it has a standard bowl-shaped rubber head,

00:39:36 it's perfect for flat surfaces like a sink or a bathtub.

00:39:39 But if you have a smaller bowl-shaped rubber head,

00:39:42 it's perfect for smaller surfaces like a sink or a bathtub.

00:39:45 The hole near the edge of your sink or your bathroom

00:39:48 is there to prevent overflow.

00:39:51 Thanks to it, all the excess water goes into the sink.

00:39:54 In addition, it allows your sink to flow faster.

00:39:57 The hole allows the air accumulated in the sink to escape.

00:40:00 The hole in a suction cup can save your life.

00:40:03 If it gets stuck in someone's mouth,

00:40:06 it's easy to get it out.

00:40:09 But the initial purpose of this hole

00:40:12 is simply to prevent the candy from coming out of the stick.

00:40:15 When it's made, this liquid sugar is poured onto the top of the stick.

00:40:18 The stick is hollow inside,

00:40:21 so that the candy penetrates inside from the top and side

00:40:24 through this precise hole.

00:40:27 And when it solidifies, it stays perfectly fixed to the plastic tube.

00:40:30 Most containers have a small hole at the bottom.

00:40:33 This is to evacuate the water from the stick and prevent corrosion.

00:40:36 It's also the best place to lubricate them.

00:40:39 Just add a drop of oil to it,

00:40:42 and the key will turn much more easily.

00:40:45 If you don't see any holes at the bottom,

00:40:48 the stick is supposed to be used inside.

00:40:51 Instead of opening a banana with the stem,

00:40:54 turn it over and peel it from the bottom.

00:40:57 It opens much more easily this way.

00:41:00 It's a lot easier than you might think.

00:41:03 Look at the blade. It's made up of parallel sections.

00:41:06 When the blade is soft, you have to break the top part.

00:41:09 You can do this with the cap

00:41:12 that you'll find at the bottom of the instrument.

00:41:15 In no time, you'll have a sharp blade again.

00:41:18 The bands on the headphone jacks

00:41:21 allow you to isolate the wires from each other.

00:41:24 One band means that the headset has a mono signal.

00:41:27 The other band means that the headset has an integrated microphone.

00:41:30 You can usually find silicon gel in bags,

00:41:33 shoes and many other items you buy.

00:41:36 This gel absorbs excess moisture.

00:41:39 Don't throw it away.

00:41:42 Every time your shoes are wet,

00:41:45 put a few bags of silicon gel in them.

00:41:48 It's very convenient to use tweezers to organize your cords.

00:41:51 Just take a tweezer and several cords

00:41:54 and tie them together.

00:41:57 You can also write notes on labels and use them as a memory aid.

00:42:00 You've probably noticed that train and bus seats

00:42:03 are covered in fabric with strange patterns.

00:42:06 Do you know why?

00:42:09 They use these patterns to hide any stains on the seats.

00:42:12 The brighter the color, the more patterns there are,

00:42:15 so it's hard for a passenger to notice the stains.

00:42:18 In addition, the patterns are usually so light

00:42:21 that no one wants to look at them for a long time

00:42:24 to spot the stains.

00:42:27 No bus or train will ever have white seats.

00:42:30 It's a certainty.

00:42:33 Speaking of buses, there are still questions to be answered.

00:42:36 For example, why are buses rarely equipped with seatbelts?

00:42:39 Buses are practically much safer than cars

00:42:42 because they are specially designed in this way.

00:42:45 We use the principle of compartmentalization.

00:42:48 This means that the seats have raised cushions

00:42:51 that absorb the energy of a possible impact.

00:42:54 They are also placed close to each other

00:42:57 so that there is less space to be propelled in case of impact.

00:43:00 In addition, in a bus, passengers are seated quite high

00:43:03 relative to the ground and in case of collision,

00:43:06 the force is absorbed by the floor of the bus

00:43:09 and not by the people inside.

00:43:12 In addition, a bus is much heavier than most other vehicles

00:43:15 and in case of collision, the force will be distributed differently

00:43:18 than in an ordinary car because of its weight.

00:43:21 A large part of the force is absorbed

00:43:24 and the passengers of the bus do not feel the intensity of the collision.

00:43:27 This is why smaller and lighter buses

00:43:30 that cannot distribute the force as well

00:43:33 need seatbelts.

00:43:36 And we must not forget that buses drive slowly,

00:43:39 which minimizes the risk of accidents and violent shocks.

00:43:42 The yellow bus in North America is for visibility reasons.

00:43:45 Yellow is one of the most easily visible colors for the human eye,

00:43:48 even more than red.

00:43:51 In addition, yellow is also visible in the dark,

00:43:54 in the fog and in rainy weather.

00:43:57 In fact, the color of these buses is not purely yellow,

00:44:00 it also contains a hint of orange.

00:44:03 This shade has an official name,

00:44:06 National School Bus Glossy Yellow.

00:44:09 In many cities, taxis are yellow for the same reason,

00:44:12 to be more visible at all times.

00:44:15 Do you know why buses have such large wheels?

00:44:18 These vehicles are larger than ordinary cars

00:44:21 and they are also much heavier.

00:44:24 It is therefore more difficult to maneuver them

00:44:27 and it takes a lot more force than for a car.

00:44:30 A larger wheel and a larger braking radius

00:44:33 allow the driver to turn the vehicle more easily

00:44:36 and to be more precise.

00:44:39 Trucks have large wheels for the same reason.

00:44:42 Have you ever seen these plushies hanging in front of some trucks?

00:44:45 It turns out that it is just a way for truckers

00:44:48 to customize their vehicle.

00:44:51 A bit like a mascot that represents the truck or its driver.

00:44:54 It is also a way to tell the world that the truck driver

00:44:57 is not a tough and scary guy,

00:45:00 but a sweet and sensitive person who should not be afraid of.

00:45:03 It is also a way for some truckers to explain it.

00:45:06 In Asia, there is also a belief that road accidents

00:45:09 are caused by ghosts and suspended toys

00:45:12 are a way to distract ghosts and prevent them

00:45:15 from hurting the truck.

00:45:18 Have you ever done a road trip?

00:45:21 If you are not the driver, all you have to do is to sit down

00:45:24 and do practically nothing for hours.

00:45:27 It does not seem to be a difficult task,

00:45:30 but because of this, they do not like road trips.

00:45:33 Why are they so tired?

00:45:36 Well, sitting in a car is not like sitting on a chair.

00:45:39 The brain does not relax. Instead, it controls everything that happens

00:45:42 by taking into account the movements of the vehicle

00:45:45 and ensuring that you maintain the right posture.

00:45:48 Your brain is constantly working, exchanging information with your muscles.

00:45:51 So your body is also working.

00:45:54 Some people get tired because of this.

00:45:57 But it does not matter.

00:46:00 Road trips are much more pleasant because the trains do not stop

00:46:03 or change course as often as cars.

00:46:06 So the body is more relaxed.

00:46:09 Another mystery is to know why it is much more difficult

00:46:12 to remain still in the same place for 30 minutes

00:46:15 than, for example, to walk for 30 minutes.

00:46:18 Again, it seems that you do nothing when you are standing.

00:46:21 So why is it so tiring?

00:46:24 For your body.

00:46:27 When you are standing, the muscles of your legs work very hard

00:46:30 to support the mass of your whole body.

00:46:33 If you are standing, there are not many muscles that work

00:46:36 and only a few of them have to do all the work.

00:46:39 When you walk, there are more muscles that work at the same time.

00:46:42 So the work is better distributed.

00:46:45 In addition, when you are standing, your two legs work non-stop.

00:46:48 But when walking, each of them takes a little break

00:46:51 every time you take a step using the other.

00:46:54 How does the same book have different covers?

00:46:57 There are several reasons for this.

00:47:00 First of all, the cover can vary due to the target audience.

00:47:03 The edition of a book for the elderly

00:47:06 is generally different from the edition intended for the youngest.

00:47:09 The edition intended for the youngest is generally brighter and more colorful.

00:47:12 The cover can also depend on the country in which the book is sold

00:47:15 in order to attract the most positive buyers.

00:47:18 Then, the books vary from one edition to the other.

00:47:21 At the beginning, a book is printed in a small quantity

00:47:24 to see how it will behave on the market.

00:47:27 If it is a success, another edition can be printed,

00:47:30 often in a pocket book.

00:47:33 The design of the cover is generally updated for each edition.

00:47:36 In addition, if a book has been adapted for the cinema,

00:47:39 there will generally be a new version that will take advantage of the notoriety of the film

00:47:42 and will be more popular.

00:47:45 This will make it recognizable for people who have seen and liked the film

00:47:48 and will encourage them to buy the copy of the book.

00:47:51 Most books are printed on yellowish paper

00:47:54 and few have white pages.

00:47:57 But why?

00:48:00 Unless it is a large-scale edition of pocket books

00:48:03 with paper of the same quality as a newspaper,

00:48:06 that is to say, bad, the book is made with good quality paper.

00:48:09 Do not be disconcerted by the fact that the book is printed

00:48:12 on yellowish paper.

00:48:15 It is generally called "cream"

00:48:18 and it is a preference for all books

00:48:21 because it is less tiring for the eyes of the reader.

00:48:24 Ordinary white paper is whitewashed and reflects a lot of light

00:48:27 so it can be exhausting to read for a long time.

00:48:30 Yellowish paper is therefore a better option

00:48:33 and publishers use it regularly.

00:48:36 There are sometimes several white pages at the very end of a book.

00:48:39 This is because the books are printed in a bookmark.

00:48:42 A bookmark is a group of pages that the printers fold together

00:48:45 and cut to make a book.

00:48:48 A bookmark can have a different number of pages,

00:48:51 the minimum being 4, then other divisible numbers by 4.

00:48:54 Thus, a book of 300 pages in total will fit perfectly

00:48:57 and there will be no white pages left.

00:49:00 But if a book has 303 pages,

00:49:03 it will need an additional bookmark

00:49:06 and the additional pages will be blank,

00:49:09 often marked with the word "note" or "message".

00:49:12 This page is intentionally left blank

00:49:15 so that the reader knows that it does not lack any important information.

00:49:18 Have you ever wondered why most doctors

00:49:21 have a neglected writing?

00:49:24 No, there are no bad writing lessons for the medical faculties.

00:49:27 The reason why it is so common is that

00:49:30 doctors are always in a hurry and write as fast as possible

00:49:33 to keep their concentration

00:49:36 and do not have time to worry about writing nicely.

00:49:39 Do not forget that you are not the only person

00:49:42 to whom they write a prescription during a day.

00:49:45 Doctors do a lot of paperwork,

00:49:48 often working up to 10 hours in a row

00:49:51 and they are simply too tired to give you a correctly written prescription.

00:49:54 Did you notice that most songs last between 3 and 4 minutes?

00:49:57 Originally, the songs were played on a phonographic turntable

00:50:00 from a vinyl disc that turned 78 rpm.

00:50:03 Thus, the size of the vinyl determined the length of the song.

00:50:06 There were two sizes of basic discs,

00:50:09 the 10-inch, which could contain about 3 minutes of reading

00:50:12 and the 12-inch, which could contain a 4-minute song.

00:50:15 So at the beginning of the 20th century,

00:50:18 if an artist wanted his song to be broadcast,

00:50:21 he could not make it too long

00:50:24 if he wanted to be able to sell a record.

00:50:27 The length of the songs was not much changed,

00:50:30 but most of the songs still lasted 3 to 4 minutes.

00:50:33 The reason why we were so attached to this structure

00:50:36 was also due to radio broadcasting.

00:50:39 If a song was too long, it was cut in half

00:50:42 or some parts were deleted so that they would enter the radio standards of 3 to 5 minutes.

00:50:45 If an artist wanted his song to go on the radio

00:50:48 and if he wanted to make money thanks to it,

00:50:51 he had to do his best to create a song that corresponded to the standard

00:50:54 so that the whole song could be played without modifications.

00:50:57 Today, even if there are longer songs,

00:51:00 those of 3 to 4 minutes have become a tradition

00:51:03 that artists maintain most of the time.

00:51:06 The small metal buttons of jeans, also called rivets,

00:51:09 were used to make the pockets of the miners more resistant

00:51:12 to fill them with heavy tools.

00:51:15 They are still useful today because they strengthen the seams

00:51:18 and allow your jeans to last longer.

00:51:21 These tiny stripes on the letters F and J of a keyboard

00:51:24 help us find the right keys when we play the piano without looking.

00:51:27 And as they are located in the center,

00:51:30 they indicate the optimal position for the indexes.

00:51:33 In addition, the QWERTY system was invented in the early 1870s.

00:51:36 Before, keyboards looked like pianos

00:51:39 with two rows of characters classified by alphabetical order.

00:51:42 Don't blame this little thing on the cable of your computer

00:51:45 for ruining your life in the middle of the night.

00:51:48 This cylinder, whose shape and color can vary,

00:51:51 actually avoids interference from other signals,

00:51:54 such as those emitted by your phone.

00:51:57 The hole in the handle of the pots and pans

00:52:00 serves as a support for the spatulas.

00:52:03 This way, the sauce or any liquid you have stirred

00:52:06 drains into the pan, which avoids your work plan from getting dirty.

00:52:09 Speaking of handles, jerry cans have three.

00:52:12 It's a great idea to have a handle on your computer.

00:52:15 If you only have one, you will only use the central handle

00:52:18 to distribute the weight evenly.

00:52:21 But if someone wants to help you,

00:52:24 each of you can grab the side handle.

00:52:27 The lack of privacy in public toilets

00:52:30 caused by these large spaces under the doors

00:52:33 exists for a good reason.

00:52:36 1) People do their business faster and there is less waiting line.

00:52:39 And 2) In the event of a problem,

00:52:42 it will be easier to locate and help someone in need.

00:52:45 In London, some of the handles look like

00:52:48 light bulbs without bulbs.

00:52:51 Their official name is "stink pipe".

00:52:54 Because they were very useful in the 19th century,

00:52:57 these pipes made the air and explosive gases rise

00:53:00 from the basement to avoid the undesirable consequences.

00:53:03 Books are printed on large sheets

00:53:06 that can hold four printed pages.

00:53:09 If you have a large number of printed pages,

00:53:12 there will surely be an extra blank page for notes.

00:53:15 Toothbrush hairs have two secret characteristics.

00:53:18 First, the color fades over time,

00:53:21 indicating when to buy another one.

00:53:24 In addition, hairs vary in length and the longer ones

00:53:27 are used to better clean the teeth of the bottom.

00:53:30 The stripes on the toothpaste are just a marketing trick.

00:53:33 In the 1970s, a large toothpaste brand

00:53:36 made a blue stripe to show that its toothpaste

00:53:39 had a double action.

00:53:42 The toothpaste, entirely white, has exactly the same functions.

00:53:45 Originally, golf balls were smooth.

00:53:48 They now have a raised surface because players

00:53:51 noticed that used and damaged balls

00:53:54 flew better than new balls.

00:53:57 Manufacturers therefore began to produce balls with sockets.

00:54:00 The black spots on the windshield or front

00:54:03 are used to directly shade your eyes

00:54:06 by moving UV rays away and heating the glass evenly,

00:54:09 a bit like sunglasses.

00:54:12 The lens strap is only used to hang a small tree.

00:54:15 It allows you to switch between day and night mode

00:54:18 to avoid being dazzled by the headlights of the cars behind you.

00:54:21 The dots of color on the chips packets

00:54:24 help manufacturers to control the color of the packaging

00:54:27 by showing what shades have been used.

00:54:30 Your microwave is probably in silent mode.

00:54:33 Hold the 1 or 0 key down and look.

00:54:36 There is also sometimes a simple button to mute.

00:54:39 But since there are no identical microwaves,

00:54:42 it can always be useful to take a look at the manual.

00:54:45 The loops on the supermarket carts

00:54:48 help you organize your things better when you shop.

00:54:51 You wouldn't want to put your pretty white jacket

00:54:54 under your carrots and onions, would you?

00:54:57 The stickers on fruits say a lot about their past.

00:55:00 A number with 5 digits starting with 9 is a good sign.

00:55:03 It's an organic product.

00:55:06 A number with 4 digits starting with 3 or 4

00:55:09 means it's a product from conventional agriculture.

00:55:12 If the number starts with an 8 and there are 5 digits,

00:55:15 it's better to leave it in the box.

00:55:18 Lip pencils and pencils for automatic eyes

00:55:21 have an integrated pencil size.

00:55:24 The back of the pencil doesn't only show its color.

00:55:27 You can remove it and cut the pencil.

00:55:30 If you don't want to peel your orange,

00:55:33 cut it at the top and bottom, make a slit on one side

00:55:36 and pull on the skin to open it.

00:55:39 The toothpicks sometimes have grooves that serve to create a support.

00:55:42 It's easy to break these toothpicks in half

00:55:45 and the smallest part can be used to avoid

00:55:48 the contact of the tip with the table.

00:55:51 The tips of the toothpicks or the lipstick are often sealed

00:55:54 by a plastic or aluminum lid.

00:55:57 Opening them with your nails is not practical.

00:56:00 The tip in the cap makes it easier to open them.

00:56:03 Some jackets have small pockets above the normal pockets.

00:56:06 They are called ticket pockets

00:56:09 because they were used to quickly get train tickets

00:56:12 before getting on the train.

00:56:15 You may have heard that the drawer under your oven

00:56:18 is hot when guests are late.

00:56:21 But you can also use it to cook at low temperature.

00:56:24 All the bottles used to be green,

00:56:27 but it turns out that brown ones are much better

00:56:30 to block UV rays.

00:56:33 A one-dollar bill hides many secrets.

00:56:36 A large letter with a border indicates which bank issued this bill.

00:56:39 Twelve banks of the Federal Reserve print them.

00:56:42 So if you want to know where a ticket comes from,

00:56:45 you can look for these small codes.

00:56:48 The wrinkled edges on the coins are not there to look pretty.

00:57:09 The weight of the coins made of precious metal

00:57:12 changed the real value of each one.

00:57:15 Before, people would wrinkle the edges and melt the metal

00:57:18 to make new coins.

00:57:21 To avoid this, the Molleyers added this pattern

00:57:24 to easily notice the wrinkled coins.

00:57:27 The small holes under the cups keep them better in place

00:57:30 on wet surfaces and they avoid water accumulation

00:57:33 when they are in a dishwasher.

00:57:36 To enjoy a fresh and tender peanut butter more,

00:57:39 the Molleys are placed in a uniform distribution throughout the pot.

00:57:42 The bath foam has a thermoregulatory function.

00:57:45 The bubbles keep the water warm

00:57:48 so that you can enjoy your bath a little longer.

00:57:51 Be careful, this only works with acrylic baths.

00:57:54 Metal baths lose heat faster,

00:57:57 no matter how much foam there is.

00:58:00 The brass door handles, bronze and alloy,

00:58:03 made of copper, have an antimicrobial effect

00:58:06 and a metallic finish.

00:58:09 The small V-shaped seam at the bottom of the collar

00:58:12 of some baths allows you to put them on without distorting them

00:58:15 because they are made of a double layer of mesh fabric,

00:58:18 just like the waist and the sleeves.

00:58:21 To avoid spilling fruit juice on your T-shirt,

00:58:24 try to pour it by putting the brick the other way around.

00:58:27 There will be fewer splinters.

00:58:30 The triangular flaps on the small juice bricks

00:58:33 are made of a special material called polyester.

00:58:36 If you take them off and use them as handles,

00:58:39 you won't squeeze the packaging and you'll avoid accidents.

00:58:42 All disposable cups look alike.

00:58:45 The secret lies in their shape.

00:58:48 The top is always wider so that the nose can fit in,

00:58:51 while you drink and the bottom is always narrower

00:58:54 to hold it better, even with small hands.

00:58:57 In addition, the difference in width allows the cup to stack up.

00:59:00 You can put it directly on your blender by screwing it on

00:59:03 so that you don't have to wash the blender after you've done your milkshake.

00:59:06 The only rule is not to set the machine to maximum power.

00:59:09 It is not necessary to tear the edges of the sugar sachets.

00:59:12 The best method is to break them in the middle.

00:59:15 It's less than a small piece of torn paper.

00:59:18 The double zippers are an excellent protection against pickpockets.

00:59:21 You can put a small padlock on these zippers

00:59:24 so that no one but you can open them.

00:59:27 When you have something stuck between your teeth,

00:59:30 it can be difficult to remove it with a toothpick.

00:59:33 If you tie a knot in the thread, you can easily get rid of the leftovers.

00:59:36 The tiny hole at the bottom of the padlocks

00:59:39 is used to evacuate water to avoid rust.

00:59:42 It is also used to lubricate the padlock by putting a drop of oil in it

00:59:45 to make it easier to open and close.

00:59:48 The small plastic disc is located on the back of the cup

00:59:51 and is used to lock the padlock in place.

00:59:54 The small plastic disc in the cap of a bottle

00:59:57 is what keeps it from being too tight

01:00:00 because it holds the gases inside.

01:00:03 Without it, your coca would be like sweet water.

01:00:06 It is a myth that the pink side of the eraser

01:00:09 holds the pencil and the blue side the ink.

01:00:12 The blue side is used to erase the thicker paper.

01:00:15 It works mainly for the pencil,

01:00:18 but be careful not to tear your paper.

01:00:21 But this little blue thing can do a lot more.

01:00:24 It can polish your jewelry or clean your electronic devices,

01:00:27 like the screen on your phone.

01:00:30 And you see those stickers that never come off?

01:00:33 The blue eraser comes to the end,

01:00:36 just like the traces of dirt on the cloth or on the walls.

01:00:39 Glass bottles usually have a kind of hole in the bottom called a "pillow".

01:00:42 It is convenient for those who serve glasses

01:00:45 because this hole prevents the bottle from slipping out of their hands.

01:00:48 Cotton packets are equipped with strings

01:00:51 to hang them on a support.

01:00:54 You don't have to open and close the packet every time.

01:00:57 Look below, there is a perforated line.

01:01:00 Tear it and simply pull a disc when you need it.

01:01:03 If you lick a Nintendo game cartridge,

01:01:06 you will notice that it leaves a bitter and disgusting aftertaste.

01:01:09 They are covered with Benzoate de Benatonium,

01:01:12 which gives a disgusting aroma.

01:01:15 It's a good idea to put the games in your mouth.

01:01:18 Bottles have a long neck for a good reason.

01:01:21 By holding it by the neck and not by the body,

01:01:24 your drink will stay fresh longer.

01:01:27 It's the same for glass bottles, so hold them properly.

01:01:30 The button, located at the back of the shirt collar,

01:01:33 serves to hold the tie in place.

01:01:36 But the fine ties for which this button was designed

01:01:39 are no longer as popular today,

01:01:43 as they were in the past.

01:01:46 Women's shirts often have buttons on the left

01:01:49 because before, high society women had maids

01:01:52 who helped them get dressed.

01:01:55 It was more convenient for them to button the shirts with the buttons on the left.

01:01:58 A bag of silica gel is often found in bags,

01:02:01 shoes and other objects you buy.

01:02:04 It is used to absorb excess humidity,

01:02:07 so as soon as your shoes are wet,

01:02:10 you can use it to dry them.

01:02:13 You probably don't use your shampoo well.

01:02:16 The main thing you should know is that you should not apply it directly on your hair,

01:02:19 but only on the roots.

01:02:22 The foam created will be enough to clean your hair.

01:02:25 The margins of notebooks were invented to protect the notes.

01:02:28 People used to live with rats,

01:02:31 and these rodents often scribbled on the paper.

01:02:34 Thanks to the margins, they couldn't scribble on the written part.

01:02:37 The red bubbles used for the parties can measure the liquids.

01:02:40 The bottom line corresponds to 30 ml,

01:02:43 the second line corresponds to 150 ml

01:02:46 and the third line corresponds to 350 ml.

01:02:49 The little arrow next to the fuel gauge

01:02:52 on the dashboard of a car

01:02:55 indicates which side the tank hatch is on.

01:02:58 It is useful when you have to fill up a rental car.

01:03:01 The stripers on each side of the road are very useful.

01:03:04 They can prevent you from falling asleep.

01:03:07 When a car is driving on these strips,

01:03:10 the driver feels vibrations and hears a loud noise.

01:03:13 The rings were more than just accessories.

01:03:16 The nobles used them as a bucket.

01:03:19 They protected the fingers of the archers

01:03:22 and they prevented the seamstress from stinging herself with their needles.

01:03:25 Speaking of rings,

01:03:28 the ones on the audio headphones

01:03:31 represent different functions.

01:03:34 If your headphones have three,

01:03:37 it means that your device can produce a stereo sound

01:03:40 and that your headphones have the microphone function.

01:03:43 The kings on the playing cards

01:03:46 are real historical figures.

01:03:49 Pique, King David, Treffle, Alexander the Great,

01:03:52 Cœur, Charlemagne, Caro, Jules César.

01:03:55 We remove all the post-its incorrectly.

01:03:58 If you take them off from the top,

01:04:01 the paper will remain curved.

01:04:04 But if you take them off from the side,

01:04:07 along the sticker, they will remain flat and will stick to the wall for much longer.

01:04:10 The rolls are effective to remove the hairs,

01:04:13 but they can also clean other things.

01:04:16 You can use them to remove the dirt from the covered basket,

01:04:19 from your dishwasher for example.

01:04:22 You just have to put your roll in each compartment

01:04:25 and it will remove all the crumbs and dirt.

01:04:28 A number is inscribed on the side of many cosmetic products.

01:04:31 It is not a coincidence.

01:04:34 It indicates the life of your product once you open it.

01:04:37 That's why it has a "open pot" symbol.

01:04:40 If you usually buy your milk in this kind of plastic bottle,

01:04:43 you probably noticed these big circles on the side.

01:04:46 They absorb shocks in case of a fall

01:04:49 and also leave a little space for the container to expand.

01:04:52 This way you can see if the milk has turned without tasting it.

01:04:55 It is sometimes annoying to see that we have not used all the deodorant in the sticker.

01:04:58 There is still a little bit left, but it is too difficult to reach.

01:05:01 The trick is simple.

01:05:04 Unscrew the bottom, take a pencil and push the sticker up.

01:05:07 This way you will get all that is left.

01:05:10 The two flat brushes that can be seen on the sockets used in America

01:05:13 have holes near the edges of the container.

01:05:16 There is a hole in the bottom of the container

01:05:19 and the brush is attached to the socket.

01:05:22 This way the brushes will not come out on their own.

01:05:25 These holes also allow you to attach electric wires directly to the brushes

01:05:28 in case there is no classic electric socket.

01:05:31 So if you need to get electricity directly from the cables,

01:05:34 these holes will make your job easier.

01:05:37 The airplane's shutters also have small holes.

01:05:40 This is one of the essential features of the airplane.

01:05:43 The airplane's shutters are designed to be used in the air.

01:05:46 They protect passengers from external pressure

01:05:49 and also balance the pressure on the shutters when the plane takes off.

01:05:52 A spoon is attached to a hole in the handle,

01:05:55 which can certainly be useful when you take the pasta out of the water

01:05:58 and want to drain it.

01:06:01 But it is also a good measuring tool

01:06:04 because the hole corresponds to a portion of spaghetti.

01:06:07 Sometimes things have a specific purpose.

01:06:10 Sometimes things have a specific purpose.

01:06:13 But you can always give them other functions.

01:06:16 For example, if you want to eat apple compote

01:06:19 but you don't have a spoon,

01:06:22 you just have to take the lid and fold it so that it becomes a spoon.

01:06:25 You can work your agility with chopsticks

01:06:28 by trying to catch your Chinese noodles

01:06:31 in the corners of the cardboard box,

01:06:34 but you can also open the last one to make a plate out of it.

01:06:37 According to a theory,

01:06:40 these funny pompoms on the sailors' hats

01:06:43 appeared in the 18th century in the French Navy

01:06:46 because the sailors were tired of banging their heads against the ceilings of the ships.

01:06:49 because the sailors were tired of banging their heads against the ceilings of the ships.

01:06:52 Before, the ads weren't shown before the films, but after.

01:06:55 That's why they're also called "trailers",

01:06:58 which means "remarks" in English.

01:07:01 Wooden belts still occupy a large part of the market

01:07:04 because the cedar wood, which they are generally made of,

01:07:07 is a natural oil that repels mites and preserves clothes.

01:07:10 To know if a hard egg is fresh or not,

01:07:13 just peel it.

01:07:16 The harder it is to clean, the fresher it is.

01:07:19 There is another trick for eggs. Try to turn them.

01:07:22 If an egg turns regularly, it is cooked.

01:07:25 If it turns slowly or not at all, it is raw.

01:07:28 When you're hungry or even just a little hungry,

01:07:31 cooking is probably your favorite thing to do.

01:07:34 And you probably think you know it very well.

01:07:37 In fact, maybe not as well as you think.

01:07:40 Your kitchen contains a lot of little hidden secrets

01:07:43 that you probably never realized.

01:07:46 First of all, we're going to look at something that has holes.

01:07:49 No, we're not going to talk about gruyères.

01:07:52 Although all this discussion about the kitchen has probably opened your appetite.

01:07:55 Instead, take a look at your kitchen knives.

01:07:58 You may notice that some of them have holes

01:08:01 or grooves through the blade.

01:08:04 These characteristics are not unique to a single type of blade.

01:08:07 Many of your knives probably have these holes or grooves.

01:08:10 It could be a knife for peeling, a knife for painting

01:08:13 and, of course, everyone's favorite kitchen knife,

01:08:16 the chef's knife.

01:08:19 This feature is not only decorative.

01:08:22 There are several good reasons for the presence of these holes and grooves.

01:08:25 One of the main ones is to reduce the friction of the cut.

01:08:28 All foods are not easy to cut into slices.

01:08:31 Let's say you're trying to make a delicious potiron curry.

01:08:34 Of course, you have your main ingredient

01:08:37 and you may want to add some carrots or other vegetables

01:08:40 that are all quite thick and difficult to cut.

01:08:43 Then choose a knife with holes or grooves.

01:08:46 They will help reduce the friction between the food that is difficult to cut and your blade.

01:08:49 This knife will also be lighter

01:08:52 and, consequently, will cause you less friction.

01:08:55 The holes in the blade mean less steel,

01:08:58 which means less weight.

01:09:01 You will therefore be able to cut your food more easily.

01:09:04 Another function of these holes is to be able to suspend your knives,

01:09:07 especially the larger ones, which are more difficult to store in a drawer.

01:09:10 For a knife that is frequently used, like an axe,

01:09:13 having it hanging at hand is also practical.

01:09:16 The blade is also very light and, consequently,

01:09:19 will cause less pain in the wrist if you have to cut food for a long time.

01:09:22 Of course, when you cut your food,

01:09:25 you will want to do it on a cutting board

01:09:28 which, you guessed it, has its own secret.

01:09:31 You will notice that on most boards,

01:09:34 there is a hole at the top of this one.

01:09:37 Of course, this can be practical when you have to transport it

01:09:40 or suspend it in your kitchen, as you do with your axe.

01:09:43 But this feature also has another practical function

01:09:46 that probably hasn't caught your attention until now.

01:09:49 Once you have cut your herbs and vegetables

01:09:52 and all those delicious things that you will add to your dish,

01:09:55 place the hole of the cutting board over your pan or saucepan.

01:09:58 Grab your knife and gently push your ingredients through the hole

01:10:01 to drop them into the container without spilling any

01:10:04 and thus without dirtying your worktop or your cooking plates too much.

01:10:07 Did you know that there is a secret way to cut onions without crying?

01:10:10 First of all, it is important to know

01:10:13 that there is a secret way to cut onions without crying.

01:10:16 First of all, it is important to know that your onion is not a revenge.

01:10:19 It doesn't do you any harm to make you cry when you cut it.

01:10:22 The skin of the onion actually contains amino acids.

01:10:25 When you cut it, the chemical compounds produced by the cloves

01:10:28 are released into the air and end up stinging your eyes.

01:10:31 The best way to quench the emissions of these chemical compounds

01:10:34 that cause tears is to cool the onion,

01:10:37 either by freezing it or by putting it in cold water.

01:10:40 In both cases, you should now be able to cut your onion without crying.

01:10:43 In both cases, you should now be able to cut your onion without crying.

01:10:46 In both cases, you should now be able to cut your onion without crying.

01:10:49 Let the water flow for our next kitchen secret

01:10:52 and then we will fill the ice cream containers.

01:10:55 It seems almost impossible to fill these containers

01:10:58 without wasting a lot of water.

01:11:01 But the design of an ice cream container must precisely allow

01:11:04 to fill it easily without flooding your kitchen.

01:11:07 Rather than filling each hole one by one,

01:11:10 you should fill the flat area between each hole.

01:11:13 This will allow you to channel the water uniformly

01:11:16 in each hole without flooding the sides.

01:11:19 If you are looking for a faster way to fill your ice cream container,

01:11:22 tilt it and pour the water into the two upper holes.

01:11:25 The water will flow along the container like a waterfall

01:11:28 and fill each hole quickly and neatly.

01:11:31 Of course, transporting the ice cream container from the kitchen tap to the freezer

01:11:34 is still a difficult step.

01:11:37 And we have not yet discovered any secret for this,

01:11:40 except for the automatic ice cream maker.

01:11:43 Now, let's get out of the freezer and warm up a little.

01:11:46 Did you know that spicy foods are not really hot?

01:11:49 At least not in the traditional sense of the term.

01:11:52 A chemical compound present in hot peppers called capsaicin

01:11:55 deceives your brain so that it feels this burning sensation

01:11:58 in your mouth and in your throat.

01:12:01 But don't worry, you're not alone.

01:12:04 Even if you feel like it.

01:12:07 Your first reflex is probably to take a big glass of water

01:12:10 and drink it all at once, as if you wanted to put out a fire.

01:12:13 But that's exactly what you shouldn't do.

01:12:16 The water will only spread the capsaicin further

01:12:19 and aggravate the situation.

01:12:22 Instead, dairy products will be your best allies

01:12:25 if you need to relieve the pain of a spicy pepper.

01:12:28 Most dairy products contain a protein called casein.

01:12:31 It can help rinse the capsaicin.

01:12:34 So, as long as you have a glass of milk at hand,

01:12:37 don't hesitate to try some of the high-end seasonings.

01:12:40 Speaking of seasonings,

01:12:43 the most common seasoning is, without a doubt, salt.

01:12:46 But have you ever managed to catch the salt shaker

01:12:49 half full, turn it over and,

01:12:52 even if you shook it and hit the bottom of it,

01:12:55 to see almost no grain coming out?

01:12:58 Sooner or later, the salt begins to agglomerate.

01:13:01 This tends to happen because the salt can absorb

01:13:04 the water vapor in the air

01:13:07 and eventually dissolve and agglutinate.

01:13:10 The secret solution to this problem

01:13:13 has been under your nose all this time

01:13:16 and you probably never noticed it.

01:13:19 Have you ever been surprised by the presence of a few grains of rice

01:13:22 in the dishwasher on the table of your favorite restaurant?

01:13:25 They are not there to make it look nice or to add flavor,

01:13:28 but because the rice absorbs the water even faster than the salt,

01:13:31 which keeps it dry longer.

01:13:34 You can do the same with the salt in your own kitchen.

01:13:37 Just add a few grains of uncooked long rice in your dishwasher

01:13:40 and you'll notice that your salt will come out much more easily.

01:13:43 Now let's talk about something you can flavor

01:13:46 with your dishwasher now easy to use,

01:13:49 or rather what tends to come out.

01:13:52 As Sam Gamgee rightly put it in "The Lord of the Rings",

01:13:55 potatoes are one of the most varied foods on the planet.

01:13:58 They can be tasted in broth, puree,

01:14:01 in slices in a stew,

01:14:04 but if you don't decide to cook your potatoes as quickly as a hobbit,

01:14:07 you'll probably notice that sprouts are starting to germinate.

01:14:10 Pretty quickly, your potato looks like something

01:14:13 from a scary science fiction movie.

01:14:16 However, it is not a counter-natural process.

01:14:19 Like most living things,

01:14:22 reproduction is part of the potato's life cycle,

01:14:25 and germination is part of the process of creating a new potato.

01:14:28 The speed at which your potato starts to germinate

01:14:31 depends on its exposure to light,

01:14:34 temperature, humidity levels,

01:14:37 and the duration it stays asleep.

01:14:40 If it stays at rest for a while, it will probably have sprouts.

01:14:43 That's great news if you plan to plant your potato.

01:14:46 But not so much if you plan to eat it.

01:14:49 However, a secret to prevent potatoes from germinating too early

01:14:52 is to store them with apples.

01:14:55 The ethylene gas emitted by these apples

01:14:58 slows down the germination process.

01:15:01 However, don't store your potatoes with your onions.

01:15:04 No, they won't make your potatoes cry,

01:15:07 but they will have the opposite effect and will make them germinate.

01:15:10 Anyway, germination on a potato

01:15:13 is far from as unpleasant as the mold on the bread.

01:15:16 When the bread is fresh,

01:15:19 one of the most common uses is to make toasts out of it.

01:15:22 Almost everyone has a grey bread.

01:15:25 And you may be surprised to learn

01:15:28 that there is probably a secret drawer inside yours.

01:15:31 What is in this compartment may not be very exciting,

01:15:34 but it turns out that it is an essential function

01:15:37 that few people know about.

01:15:40 It is the crumb drawer.

01:15:43 All the crumbs and debris from your toasts land here.

01:15:46 To find this hidden drawer,

01:15:49 you have to look for it between the upper and lower parts of your grey bread.

01:15:52 It is essential to keep this drawer clean.

01:15:55 Not only does it keep your kitchen less dirty,

01:15:58 but it also reduces the risk that your grey bread will cause a fire.

01:16:01 It would be regrettable.

01:16:04 There you go, now you know a few more kitchen secrets.

01:16:07 You will be able to get to know your kitchen again

01:16:10 and prepare a good meal

01:16:13 while keeping all these tips in mind.

01:16:16 Bon appétit!
