00:00You must have noticed those lines on some kinds of chips.
00:04For one thing, they help with the distribution of spices and seasonings.
00:08In other words, all those substances that make your chips taste like cheese
00:12are mostly stored inside the lines.
00:16Plus, the lines make chips crunchier.
00:20Some cars have a tiny coffee cup sign on their dashboard.
00:24It's the vehicle's anti-drowsiness mechanism.
00:28There are manufacturers that equip their cars with a drowsiness detection system.
00:33It analyzes the speed, wheel angle, and lane deviations
00:37to figure out if it's time for the driver to take a break.
00:41If it is, the vehicle makes several audio signals,
00:44and the coffee cup sign starts to flash.
00:49Some plastic milk containers have dents on their sides.
00:52These dents serve several purposes.
00:56For one thing, when milk spoils, this process usually causes swelling
01:00and high pressure buildup inside the container.
01:04That's when the dent comes in handy.
01:06It pops out and doesn't let the jug blow up.
01:10Plus, if you decide to freeze the milk, it will expand like any other liquid.
01:15And then again, the indentation will pop out
01:18and prevent the container from breaking inside your freezer.
01:22You might have wondered why jerry cans have three handles.
01:26It's a clever designer move.
01:29This way, if you carry the container alone,
01:32you can use only the central handle to distribute the weight evenly.
01:37But if your friend wants to help you out, each of you can grab the side handle.
01:43The first jeans had a problem.
01:45Workers and miners, who were the original jeans wearers,
01:49put too much pressure on the poor piece of clothing.
01:52As a result, the seams couldn't withstand the stress and tore.
01:57Tiny metal studs were invented to prevent this from happening.
02:03Sticky notes come off relatively easily
02:05because their adhesive is spread out across the paper unevenly in small blobs.
02:11And only some of these blobs touch the surface of whatever you've stuck the note on.
02:15That's why when you unstick a post-it and attach it to something else,
02:19it still works until all the glue gets used or covered with dirt.
02:25Soda bottles are always filled in such a way
02:28that there's some space between the liquid and the cap.
02:32That's because soda contains carbon dioxide.
02:36It's a gas that can expand once a bottle is heated.
02:39If there's no gap in the bottle,
02:41it can break because of the pressure building inside.
02:45Also, when you open your drink,
02:48the gases go out in the form of bubbles,
02:50and the drink is likely to overflow.
02:52The gap helps with this problem too.
02:57Dental floss is super useful for your teeth,
02:59but it might be rather hard to operate.
03:02It regularly slips out of your fingers and tangles.
03:06To avoid these problems,
03:08tear off a piece of dental floss and tie its two ends together.
03:12It'll be much easier to use and won't hurt your fingers.
03:17Now, about those horizontal lines on plastic bottles.
03:21They help hold bottles up.
03:24Some bottles are produced from soft plastic.
03:27Without the lines, they wouldn't keep their shape.
03:30Instead, they would twist easily or even break.
03:35The soft round part under a soda bottle cap keeps the carbonation from escaping.
03:41Without it, your pop would go flat in no time.
03:45Probably even before you buy it.
03:49If you don't have anywhere to put a toothpick after using it,
03:52break off its flat end at the first groove and place it on the table.
03:57Now, you can balance the used portion of your toothpick on the grooved part,
04:01so that it doesn't have to touch the table.
04:05You can also make a makeshift stand for disposable chopsticks.
04:09They have a sort of lump on one side.
04:12Break that lump off before you split the pair.
04:16Now, when you want to take a sushi break,
04:18just place the stick on this stand.
04:23Donuts are shaped like rings because otherwise they might get overdone at the edges,
04:28but uncooked and gooey inside.
04:31With a hole in the center, both the outside and the inside get ready at the same time.
04:39Ever notice that layer of clear fluid in gel pens?
04:42It's called the ink follower or stopper fluid.
04:47The gel in such pens contains pigment particles dissolved in a polymer solution.
04:53The gel should be thick enough to keep the pigment particles suspended,
04:57but also thin enough to flow first onto the ball and then the paper.
05:02The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
05:08out.
05:09Without this transparent fluid, your gel pen wouldn't function.
05:14The fluid always stays in one position and doesn't get dissolved with the gel.
05:19Neither does it move backward or flow out of the pen.
05:24Some button-down shirts have a button hidden on the back of the collar.
05:28Its main purpose is to prevent the tie from sticking out from under the collar.
05:34As for that locker loop on the back,
05:37you can use it to hang the shirt on a hook to avoid wrinkling it.
05:43Outer rings and zipper sliders, especially when two sliders are used together,
05:48are added so that you can connect them with a lock and keep sticky fingers away.
05:55Most ambulance cars have this word printed on the front of the vehicle.
05:59That's the word ambulance backward.
06:03It's written in reverse so that the driver in front of the ambulance can see the word properly in their
06:08rear-view mirror.
06:10Then they can move out of the way and let the ambulance pass.
06:15Escalator brushes serve an important safety purpose.
06:19You might have heard that most accidents happen after people get their bags or clothes stuck in escalators
06:25because they stand too close to the sides.
06:28But when there are nylon brushes on both sides,
06:31you can't but keep your feet away from the escalator's skirt panels.
06:34The result? No accidents.
06:38The side holes in sneakers are for laces.
06:42Since sneakers were originally invented for basketball players,
06:46this interesting design allowed them to accommodate any player's foot.
06:51They just needed to lace their sneakers in the most comfortable way for them.
06:56The holes in the bottoms of your earphones allow air to circulate up and through the speakers.
07:02It helps to increase low frequencies, making the bass sound deeper.
07:07The quality of the sound also becomes much better.
07:11Ever been stranded with a cup of applesauce but no spoon at hand?
07:17But each snack pack already has a built-in spoon.
07:21Several twists of the foil lid and here you go.
07:26Diamond slits on backpacks were originally placed only on traveler bags.
07:31Their purpose was to carry robes.
07:34These days, you can find such slits on almost every backpack.
07:39Why not use them to carry a bottle of water, an umbrella or a pair of sneakers?
07:46Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
07:53Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black
07:59and white photocopying.
08:02Photocopiers perceive yellow and light green marks as almost non-existent and don't print them.
08:09A stop sign has an octagonal shape to help drivers recognize it easily, even if they see it from the
08:15back.
08:16When the signs weren't reflective yet, this shape prevented drivers from confusing the stop sign with any other at night.
08:24The number 57 on a Heinz ketchup bottle has nothing to do with the product label.
08:30The truth is that the place with the numbers is the very sweet spot you should tap to get the
08:36ketchup flowing.
08:38So, stop hitting the bottom of your sauce bottle and hit 57.
08:44Lots of private houses have triangular shaped roofs because this allows rain, snow and fallen leaves to slide off the
08:52slope.
08:53If all this stuff piled up on top of your house, one day your roof would collapse.
09:00Airplane windows have rounded edges and that's a crucial safety measure.
09:05It prevents aircraft accidents.
09:08Weak spots are usually situated in the corners.
09:11If airplane windows were square or rectangular, each of them would have four potential weak spots.
09:17Under pressure, they would collapse.
09:22Here's how you can protect your bank card from potential fraudsters.
09:26Use a marker and cover the last four digits.
09:29You can also use a sticker that's easy to remove and place it over the security code.
09:34Have you had a house guest that didn't use a coaster?
09:37Get a hair dryer and hold it a couple of inches away from the stain.
09:40Blow it on medium heat for a couple of minutes to evaporate the watermark.
09:44If a faded ring remains, mix equal amounts of vinegar and olive oil in a bowl.
09:49Wipe it onto the marked area and rub it in until the stain disappears.
09:53Then wipe it off.
09:54Don't waste time scrubbing the burnt stains off the bottom of a pan.
09:58Instead, fill it with water and add three tablespoons of salt.
10:02Let it sit overnight as the salt dissolves the burnt marks.
10:05And in the morning, pour the water out of the pan.
10:08This way, it will be much easier to scrub all that grease off.
10:12Picture this.
10:13You're on vacation and your shirt has become all crinkled inside the luggage.
10:16You need it tonight, but the hotel doesn't have an iron.
10:20Don't panic.
10:21Hang the shirt up in the bathroom.
10:22And while you relax in a hot shower, the heat and moisture will unwrinkle your shirt.
10:27It won't be perfect, but it will get much better without any effort.
10:30The football is on and it turns out you've run out of standard batteries.
10:35You can use a smaller battery instead that easily fits inside.
10:38Now take some aluminum foil and crunch it up.
10:42Fit it into the gap on the negative or flat end of the battery.
10:45All done.
10:46You can turn on the TV now.
10:48Once your flip-flops crack and the plug easily slips out of the hole,
10:52it's normally a sign that you need a new pair.
10:54But there's a way to extend their mileage.
10:57Push the plug back through the hole.
10:59Then take a bread clip and attach it to the end.
11:01The clip will provide enough support for the plug to remain in place.
11:06You've received a package and the receipt is taped on.
11:09You've managed to detach it from the box.
11:11But how to separate the tape without ripping the paper?
11:14Hold both ends of the tape apart and by pulling it slowly,
11:18the tape stretches and separates itself from the paper without tearing it apart.
11:24Ziploc bags are perfect to keep things dry.
11:26But it would be great if they were larger.
11:29Take two and turn one of them inside out.
11:31They can now connect and work as one large bag.
11:34Big enough to protect a keyboard.
11:37There's no need to carry your keys in your hand when you go for a jog.
11:41Instead, put them inside your pocket.
11:43Take a rubber band, then tie it around the pocket from the inside.
11:46This stops the keys from falling out.
11:50You've broken your key in the door.
11:51It's stuck. Great.
11:53Arranging for a locksmith could cost up to $100.
11:57But for a cheaper and quicker option, try using a hot glue stick.
12:01Heat the end with a lighter and once it's warm enough to melt,
12:03push the glue into the keyhole.
12:05The melted glue will enter the available space covering part of the key.
12:10Once it cools, it compresses and gains a strong hold of the key's end.
12:15Now, just pull it out.
12:17If you need to siphon liquid through a hose
12:20and want to avoid using your mouth, put one end in the liquid
12:23and hold the other upwards with your thumb closing the top.
12:26Now shake up and down.
12:28This jiggle motion pushes liquid upwards a little each time.
12:32And once it reaches the top, lower the exit point and let gravity do the rest.
12:37You've left your keys locked inside the car.
12:39It's an older model with a roll-down window.
12:42You could get the coat hanger and begin the long process of finding the lock.
12:46Or use duct tape.
12:47Make about 20 2-foot-long strands.
12:50Stick them onto the window, allowing enough room for the tape to grab onto at the bottom.
12:55Then with a friend, take the ends of the tape, holding them together, and pull downwards.
12:59The force will allow the window to lower enough that you can unlock the door.
13:04While drilling long screws into hardwood, your old drill might not have enough power, leaving them only halfway in.
13:11Before the drill gives up, get a block of wax and scrape the edges of the screws with it.
13:16The wax works like a lubricant, melting as it gets warm and providing easy entry for the screw.
13:22You're out camping, but you didn't bring anything to light the barbecue.
13:26Take a small plastic bag that won't leak, fill it up with water, and close it tight, making a round
13:32bubble.
13:32Hold it over where you want to catch the light from the sun.
13:35The bag of water will work like a magnifying glass, starting up the barbecue, just as long as it's a
13:41sunny day.
13:42Missing a corkscrew or a cork breaking halfway?
13:46By using a stove lighter, heat the top of the bottle.
13:48The heat slightly expands the glass, and this forces the cork out the top.
13:53You've superglued your fingers again.
13:56Take some salt and pour it on top of your stuck fingers.
13:59Put your fingers into the water and slowly rub.
14:02The mixture will dissolve the glue and release you in no time.
14:06While hanging up a painting, it can be impossible to find that stubborn nail.
14:10Place a fork upside down and insert it so the nail is in between the middle fork teeth.
14:15The fork has provided a long arm that's separated from the wall, making it easier to slip the string of
14:21the painting over the nail.
14:23Once it's perfectly balanced, simply remove the fork.
14:28You need to put a cake into a container, but taking it out again later by lifting it up from
14:33the inside might ruin the cake.
14:35Put the lid upside down and place the cake on the lid.
14:39The base of the container is now the lid, making it much easier to access slice by slice.
14:46Pour out water more efficiently from large jugs and bottles by swirling.
14:50This will make the liquid inside spin, creating a vortex.
14:54The vortex allows for the air to flow back into the bottle as the water pours out.
14:59Much faster than the glugging alternative.
15:03There's an easier and less messy way to remove eggshells from a boiled egg.
15:08Once fully boiled, crack the shell on both ends by tapping them.
15:11On one end, pinch off the shell. Use the opened end to blow with your mouth.
15:16The force of air will push the flesh and expand the eggshell, forcing out the egg, undamaged.
15:24When the hinges of your laptop break, repairing them can cost up to $300.
15:29A far cheaper fix is to buy a picture frame and tape it to the back of the screen.
15:34You've dropped a small piece of jewelry on the floor, seemingly impossible to find.
15:39Take a stocking and place it over the end of the vacuum hose.
15:42Give the area a good vacuum and check the end periodically.
15:46You will eventually find it sitting at the end.
15:49You've drilled a hole in the wall, but the drill hole is now too wide.
15:53Remove the screw and find an object that is slightly shorter and thinner.
15:57Pieces of plastic, small wires, paper clips, or even toothpicks are perfect.
16:02Place whichever item you find inside the hole.
16:05It's filled the gap enough so the screw will now re-enter securely.
16:08Taking the trash out can put you in a gross scenario of getting bin juice on you.
16:13A great way to avoid this is by placing old papers at the bottom of the bag.
16:18Now, not only does it absorb all the liquids from the food and other sources,
16:22but also helps prevent bad smells from forming within a bin.
16:26Nobody likes mosquitoes and pesticides are pricey.
16:30A cheap alternative is to take a plastic bottle and cut the top part off from the bottom of the
16:35funnel.
16:36After removing it, turn it upside down and put it inside the bottle.
16:40Mix two cups of warm water with two tablespoons of sugar.
16:44The mosquitoes will be attracted to the formula inside and become trapped.
16:48Now just sit back and relax without getting bitten.
16:54Pockets are usually on the left side of shirts because most people are right-handed.
16:58Is this a myth or a fact?
17:01This is actually true.
17:02Many products favor the righties.
17:04Left-handed people will relate to this on so many levels.
17:07Let's say public transport.
17:10Have you ever noticed that the scanner at stations is typically on the right side?
17:15Household equipment and devices are one more example.
17:18Scissors, tweezers, bottle openers and many other kitchen and household appliances
17:22are designed with right-handed people in mind.
17:26The same goes for shirt pockets.
17:28While some people use both hands equally and others change their hand preference between tasks,
17:33overall, most people are right-handed.
17:36A study has revealed that 75% to 90% of the world's population are right-handed and 10%
17:42are left-handed.
17:43This means it's more convenient for most people to have pockets on the left side than on the right side
17:49of their garments.
17:50Try it out for yourself.
17:52Your elbow kind of folds when you try to reach into the pocket on the right side.
17:56Whereas on the left side, your elbow makes an arc shape,
17:59which makes it easier to put things inside the pocket and take them out.
18:04Eating more protein leads to having bigger muscles.
18:07What do you think about this, bodybuilders?
18:09Myth or fact?
18:11This is a myth.
18:13It's true that eating protein is essential for building bigger muscles.
18:17I mean, proteins are building blocks of your body.
18:19And yet, eating more than you need is unnecessary.
18:24Everyone should drink 8 glasses of water a day.
18:26Do you think this is a myth or a fact?
18:30This is a myth, so don't blame yourself for drinking less water than recommended.
18:358 glasses are not a magic number.
18:37Hydration needs differ from one person to another.
18:41How much water you should drink every day depends on your activity and exercise level.
18:46The temperature of the place where you live affects this number too.
18:49If you live in a hot area, you sweat more and need to drink more water.
18:53Soup, coffee, tea, fruits and other things you eat daily also contain water.
19:00Carrots are high in sugar, so you should avoid eating them.
19:03If this is true, we should warn bunnies.
19:06Any guesses, fact or myth?
19:09It's a myth.
19:10Carrots are about 85% water.
19:13One pound of cooked carrots only contains 3 teaspoons of sugar.
19:17Compared to the amount of sugar in desserts, this is nothing.
19:20Plus, carrots are high in phytochemicals.
19:23And eating them can help lower blood sugar.
19:27Medieval people believed in flat earth.
19:29Is this a myth or a fact?
19:32Obviously, flat earth is a myth.
19:34But so is the history built around this myth.
19:37You can't say that at those times.
19:39The whole world was skeptical about earth's spherical shape.
19:43Even everyday visible things proved that.
19:45For example, medieval people could see that the twilight glow during sunrise and sunset
19:50formed an arc over the horizon.
19:54Vikings wore horned helmets.
19:56Is this a myth or fact?
19:59The well-known image of a Viking warrior is almost always completed with a horned helmet.
20:04But in reality, there are no horns.
20:07There's no evidence that Viking helmets were horned.
20:12Detox juices cleanse your body.
20:14Is this a fact or myth?
20:17It's a myth.
20:18Detoxification doesn't work that way.
20:20Your internal organs are responsible for the process of cleansing the spleen, liver, kidneys, especially the liver.
20:28Your body is always in a natural state of cleansing itself.
20:32A person doesn't need to drink juices for detoxification.
20:36Nuts are junk food.
20:38Any thoughts?
20:39Myth or fact?
20:42You're right.
20:43This is a myth.
20:44Nuts are full of healthy fats.
20:46They're good for your heart and other organs.
20:50The average American throws away about 82 pounds of textile waste per year.
20:55Is this a fact or myth?
20:59Fact!
21:00Imagine all that waste.
21:01When someone throws their clothes away, they don't disappear into thin air.
21:05These items most likely reach landfills as their final destination.
21:10Donating clothes and selling them in second-hand stores are a much better option.
21:15Now, you've probably heard about life-saving laundry tricks that are said to make your clothes super clean and as
21:21good as they were on day one.
21:23What if those laundry tips are actually myths?
21:26I got three of them lined up for you.
21:29Shirts should be buttoned when you put them in the laundry.
21:32Is it true or not?
21:34This is a myth.
21:36You'd better keep zippers closed to keep their teeth from catching the fabric of other clothes.
21:40But fastening the buttons of a shirt can expand the button net and the button hole.
21:45In the long term, buttons will start slipping out of place.
21:49Washing clothes in hot water is the most effective way to clean them.
21:53Is this a myth or a fact?
21:56That's another laundry myth.
21:58You want to rid your clothes of germs, yet hot water alone won't be enough for this.
22:03Nowadays, many detergents can clean clothes in cold or warm water.
22:08You should remove stains from the face of the fabric.
22:12Is it true?
22:13Most people apply water and soap to the stain, starting from the front side of the fabric.
22:18But that's not the best option.
22:20A much better way is to start from the back.
22:23The stain can go deeper if you treat it from the front.
22:26Try to make the stain move up to the surface rather than push it inside.
22:32Listening to music is an effective tool for learning languages.
22:36Is it a myth or fact?
22:38It's a fact.
22:39Scientists say listening to a song and humming along can help you learn a language.
22:44Most people struggle to learn grammar.
22:46Yet, in our daily lives, we don't always follow grammar rules.
22:50Songs can help you pick up informal expressions.
22:54Scientists have also concluded that music can help you remember new words and add them to your vocabulary.
23:00Let me give you an example.
23:02It's from your first year at school.
23:04Yep, the alphabet song.
23:07Are you a morning person or a night owl?
23:10Either way, you might want to know these facts and myths about sleep.
23:15The longest someone went without sleep was 11 days.
23:18Do you think this is possible?
23:20Or is it an urban legend?
23:23This is a fact.
23:24Randy Gardner set the record for the longest amount of time a person went without sleep.
23:29It was an experiment carried out by Stanford sleep researcher Dr. William C. Demond.
23:35The doctor recorded and monitored Randy Gardner's sleep activity.
23:39Gardner managed to stay awake for 11 days and 25 minutes.
23:44Your body eventually gets used to getting less sleep.
23:48Myth or fact?
23:50It's a myth.
23:51There are many studies proving that your body and especially your brain can't get used to sleeping less.
23:57Have you noticed that after a few nights of insufficient sleep, you begin to feel groggier during the day?
24:03That's your body trying to adjust to not getting enough rest.
24:06Long-term sleep deprivation affects your daytime performance, focus, and decision-making.
24:13Many grown-ups need five or fewer hours of sleep.
24:16Can it be true?
24:18Well, this one's easy.
24:19It's a myth.
24:20Experts from the National Sleep Foundation recommend that the average adult sleeps seven to nine hours per night.
24:27Some people have a genetic mutation thanks to which they wake up refreshed after a short night's sleep.
24:33But such people are an exception.
24:35One in four million.
24:37The ability to fall asleep in any place and at any time means you're a good sleeper.
24:43What do you think?
24:44Myth or fact?
24:46It's a myth.
24:47A good sleeper gets a proper amount of sleep and has a regular sleep schedule.
24:53Cats spend two-thirds of their life asleep.
24:56Do you believe that?
24:58This will probably come as no surprise.
25:01It's a fact.
25:02How many of the facts and myths did you guess correctly?
25:06Did you know that you can actually inflate a balloon without using your lungs?
25:11All you need is a plastic bottle, vinegar, baking soda, a funnel, a rubber band, and a balloon, of course.
25:20First, pull some baking soda into the balloon using your funnel.
25:24And now, pour the vinegar into the bottle.
25:28You don't need a lot.
25:30Just fill about a third of the bottle.
25:32Let's go ahead and put the balloon over the bottle.
25:35But don't tip the soda inside the vinegar yet.
25:39Secure the balloon with a rubber band and tip it over to make the soda fall into the vinegar.
25:44And now you can step back and enjoy the show.
25:47When the baking soda and the vinegar are mixed together, they release CO2 that will inflate the balloon.
25:54You can use the inflated balloon to show your friends another trick.
25:59Grab a comb and rub it on the surface of the balloon.
26:02Now you can bend the water flow in your sink with static electricity using your brand new electrified comb.
26:09Just don't try brushing your hair.
26:12Can you really pierce a balloon without popping it?
26:15The answer is yes.
26:17You're gonna need a skewer or a long needle, a balloon, petroleum jelly, and some courage.
26:24Scratch the balloon with your fingers and make it more flexible.
26:27Now, blow steadily into the balloon.
26:30Stop before blowing it to the full size.
26:33This will make the trick easier to perform.
26:35Put some petroleum jelly on the needle.
26:38Now, find this darker area near the knot where the balloon is less stretched.
26:43And just pierce it all the way through the top, like this.
26:47Balloons are made up of polymer chains.
26:49They're so tiny that they seem invisible to the human eye.
26:52But this trick works because the polymer chains are less stretched on the neck of the balloon.
26:58It was enough room to allow the needle in between the chains without breaking them.
27:03But if you try the same technique on the sides of the balloon, it will definitely pop.
27:09By the way, hairspray actually helps keep the air in the balloon longer by sealing the surface.
27:15But if you apply hairspray on the outside of the balloon and then touch it when it's not yet dry,
27:20the balloon will shrivel.
27:22Isn't it magic?
27:26Beware, our next trick can make you question gravity.
27:29Pour some plain water into a glass bottle.
27:33Not much, about a quarter.
27:35Put the bottle in the microwave for a minute.
27:38Meanwhile, prepare a bowl with colored water to make the trick more visual.
27:42Take the bottle out of the microwave, turn it upside down and pour it into the colored water.
27:48The bottle will soon begin to fill with water.
27:51Can you guess why?
27:53The air expands when it's heated.
27:56The bottle and the air began to cool down and the air contracted, which caused the water to move.
28:03Not only wizards can make things disappear.
28:06Fill a plastic container or transparent glass with sunflower oil.
28:11Dip a glass rod inside the oil.
28:14Can you see it now?
28:16Oil and glass bend light the same way because they have almost equal refractive indexes.
28:22Therefore, it's impossible to see how the wand bends light inside the oil.
28:28To make this trick even more epic, pour equal parts of water and oil inside a glass and dip the
28:34glass rod inside it.
28:36You'll see it in the water, but it will disappear inside the oil.
28:42Have you seen this epic instant freezing trick?
28:45Here's how you can repeat it at home.
28:48Grab a small plastic bottle of clean drinking water.
28:51Leave it for about 4 hours to bring it to room temperature.
28:55And now, put it into a freezer and wait for an hour and a half.
28:59After that, take it out very carefully.
29:02Try not to shake it at all.
29:04Now, hit the bottle strongly or shake it and see what happens.
29:10Not only is red cabbage rich in fiber and vitamins, but it's also pretty useful for homemade scientific experiments.
29:18Boil red cabbage in pure water and wait until the water gets colored.
29:23Red cabbage contains a chemical called anthocyanin.
29:27It changes color when it's mixed with an acid or a base.
29:30That's why if you mix your cabbage with water with different ingredients, you'll get different colors.
29:36Bases like soda will make it blue, but acids on the contrary will create reddish colors.
29:42You can prove it by adding some lemon juice to your cabbage water.
29:46The water will become pinkish.
29:49And if you add vinegar, you'll get an even more vibrant pink color.
29:55If you have a juicer, you can try the same experiment with red cabbage juice.
29:59Initially, it will have a more vivid purple color.
30:02But under the influence of additional liquids, the color will change.
30:07Can you guess which color you'll end up with if you mix cabbage juice with bleach?
30:12It's almost transparent, but still has a greenish yellow tinge.
30:18The next trick is very trendy among artists.
30:21Here's what you're gonna need.
30:22Liquid soap, cotton buds, milk, and acrylic paints.
30:26You can use food coloring for this tip.
30:29Pour a little bit of milk into a wide bowl or a plate.
30:33You don't need a lot.
30:34Then, put a few drops of paint into the milk.
30:37And now, dip a cotton bud covered with soap.
30:41The patterns will begin to change.
30:43That's because the fatty molecules in the milk get attracted to the molecules of soap.
30:48When you're satisfied with the pattern, you can put a sheet of paper on top of the milk.
30:53And voila! Your abstract masterpiece is ready.
30:57In fact, this technique is related to an ancient paper marbling called ebrew.
31:03Artists created colorful patterns by sprinkling and brushing color pigments on a pan of oily water.
31:09And then transformed those patterns on paper.
31:14Friction helps people walk on the road instead of sliding on it.
31:17And it also allows us to perform this cool experiment called floating rice.
31:23Fill a small plastic bottle with rice.
31:26You can use a funnel to make the task easier.
31:29Shake the rice for a while.
31:30And now, try to push a chopstick or a pencil inside the bottle.
31:34If you did everything right, the stick will get stuck in the rice.
31:38You can also try using different types of grains and see what happens.
31:44Have you ever tried to put an ice cube into oil?
31:47Well, you can try today.
31:49It will create these cute little drops that will fall into the bottom of the glass because they're heavier than
31:54oil.
31:57Here's an easy way to stick an ice cube to a string without any glue.
32:02Place an ice cube in water.
32:04Put a piece of string on top and sprinkle it with salt.
32:08You don't need much, otherwise the ice will dissolve.
32:11A pinch is enough.
32:13Wait for one minute and then gently pull the string.
32:16And there you go! The ice has stuck to the string!
32:21For this experiment, you're going to need an empty, clean soda can.
32:26Turn on the kettle and wait until it begins to boil.
32:29Carefully hold the can over the kettle using kitchen tongs.
32:33It will help fill it with hot steam.
32:36When the can is full of steam, give it an ice bath.
32:39You can put it into a bowl with cold water and ice cubes.
32:43The can should wrinkle up right away.
32:46That's because the volume inside the can decreases, reducing its pressure and allowing the external pressure to crush the can.
32:55The next trick is also about air pressure.
32:58You're going to need a glass bottle, a small piece of paper, a lighter and a peeled, boiled egg.
33:04The diameter of the bottle neck should be less than the width of the egg.
33:08And it's important to use glass because plastic can melt.
33:13Now carefully light the paper, let it burn a little bit and drop it inside the bottle.
33:19Put the egg on the neck of the bottle.
33:21It should begin to bounce.
33:23And soon the pressure of air will push the egg into the bottle.
