00:00:00Pockets are usually on the left side of shirts because most people are right-handed.
00:00:04Is this a myth or a fact?
00:00:07This is actually true.
00:00:09Many products favor the righties.
00:00:11Left-handed people will relate to this on so many levels.
00:00:14Let's say public transport.
00:00:16Have you ever noticed that the scanner at stations is typically on the right side?
00:00:21Household equipment and devices are one more example.
00:00:24Scissors, tweezers, bottle openers, and many other kitchen and household appliances
00:00:28are designed with right-handed people in mind.
00:00:32The same goes for shirt pockets.
00:00:34While some people use both hands equally and others change their hand preference between tasks,
00:00:39overall, most people are right-handed.
00:00:42A study has revealed that 75% to 90% of the world's population are right-handed
00:00:48and 10% are left-handed.
00:00:50This means it's more convenient for most people to have pockets on the left side
00:00:54than on the right side of their garments.
00:00:57Try it out for yourself.
00:00:58Your elbow kind of folds when you try to reach into the pocket on the right side.
00:01:03Whereas on the left side, your elbow makes an arc shape,
00:01:06which makes it easier to put things inside the pocket and take them out.
00:01:10Eating more protein leads to having bigger muscles.
00:01:13What do you think about this, bodybuilders?
00:01:15Myth or fact?
00:01:18This is a myth.
00:01:19It's true that eating protein is essential for building bigger muscles.
00:01:23I mean, proteins are building blocks of your body.
00:01:26And yet, eating more than you need is unnecessary.
00:01:30Everyone should drink 8 glasses of water a day.
00:01:33Do you think this is a myth or a fact?
00:01:36This is a myth, so don't blame yourself for drinking less water than recommended.
00:01:418 glasses are not a magic number.
00:01:44Hydration needs differ from one person to another.
00:01:47How much water you should drink every day depends on your activity and exercise level.
00:01:52The temperature of the place where you live affects this number too.
00:01:55If you live in a hot area, you sweat more and need to drink more water.
00:01:59Soup, coffee, tea, fruits, and other things you eat daily also contain water.
00:02:06Carrots are high in sugar, so you should avoid eating them.
00:02:10If this is true, we should warn bunnies.
00:02:12Any guesses, fact, or myth?
00:02:15It's a myth.
00:02:16Carrots are about 85% water.
00:02:19One pound of cooked carrots only contains 3 teaspoons of sugar.
00:02:23Compared to the amount of sugar in desserts, this is nothing.
00:02:27Plus, carrots are high in phytochemicals.
00:02:30And eating them can help lower blood sugar.
00:02:33Medieval people believed in flat earth.
00:02:36Is this a myth or a fact?
00:02:38Obviously, flat earth is a myth.
00:02:41But so is the history built around this myth.
00:02:43You can't say that at those times.
00:02:45The whole world was skeptical about earth's spherical shape.
00:02:49Even everyday visible things proved that.
00:02:52For example, medieval people could see that the twilight glow during sunrise and sunset formed an arc over the horizon.
00:03:01Vikings wore horned helmets.
00:03:03Is this a myth or fact?
00:03:05The well-known image of a Viking warrior is almost always completed with a horned helmet.
00:03:11But in reality, there are no horns.
00:03:14There's no evidence that Viking helmets were horned.
00:03:18Detox juices cleanse your body.
00:03:20Is this a fact or myth?
00:03:23It's a myth.
00:03:25Detoxification doesn't work that way.
00:03:27Your internal organs are responsible for the process of cleansing the spleen, liver, kidneys, especially the liver.
00:03:34Your body is always in a natural state of cleansing itself.
00:03:38A person doesn't need to drink juices for detoxification.
00:03:42Nuts are junk food.
00:03:44Any thoughts?
00:03:45Myth or fact?
00:03:48You're right.
00:03:49This is a myth.
00:03:51Nuts are full of healthy fats.
00:03:53They're good for your heart and other organs.
00:03:57The average American throws away about 82 pounds of textile waste per year.
00:04:02Is this a fact or myth?
00:04:05Fact!
00:04:06Imagine all that waste.
00:04:08When someone throws their clothes away, they don't disappear into thin air.
00:04:11These items most likely reach landfills as their final destination.
00:04:16Donating clothes and selling them in second-hand stores are a much better option.
00:04:21Now, you've probably heard about life-saving laundry tricks that are said to make your clothes super clean and as
00:04:28good as they were on day one.
00:04:29What if those laundry tips are actually myths?
00:04:33I got three of them lined up for you.
00:04:36Shirts should be buttoned when you put them in the laundry.
00:04:38Is it true or not?
00:04:41This is a myth.
00:04:42You'd better keep zippers closed to keep their teeth from catching the fabric of other clothes.
00:04:47But fastening the buttons of a shirt can expand the button net and the buttonhole.
00:04:51In the long term, buttons will start slipping out of place.
00:04:56Washing clothes in hot water is the most effective way to clean them.
00:05:00Is this a myth or fact?
00:05:02That's another laundry myth.
00:05:04You want to rid your clothes of germs.
00:05:06Yet, hot water alone won't be enough for this.
00:05:09Nowadays, many detergents can clean clothes in cold or warm water.
00:05:15You should remove stains from the face of the fabric.
00:05:18Is it true?
00:05:20Most people apply water and soap to the stain, starting from the front side of the fabric.
00:05:25But that's not the best option.
00:05:27A much better way is to start from the back.
00:05:29The stain can go deeper if you treat it from the front.
00:05:32Try to make the stain move up to the surface rather than push it inside.
00:05:38Listening to music is an effective tool for learning languages.
00:05:42Is it a myth or fact?
00:05:44It's a fact!
00:05:46Scientists say listening to a song and humming along can help you learn a language.
00:05:51Most people struggle to learn grammar.
00:05:53Yet, in our daily lives, we don't always follow grammar rules.
00:05:57Songs can help you pick up informal expressions.
00:06:00Scientists have also concluded that music can help you remember new words and add them to your vocabulary.
00:06:07Let me give you an example.
00:06:08It's from your first year at school.
00:06:10Yep, the alphabet song.
00:06:13Are you a morning person or a night owl?
00:06:16Either way, you might want to know these facts and myths about sleep.
00:06:21The longest someone went without sleep was 11 days.
00:06:25Do you think this is possible?
00:06:26Or is it an urban legend?
00:06:29This is a fact!
00:06:31Randy Gardner set the record for the longest amount of time a person went without sleep.
00:06:36It was an experiment carried out by Stanford sleep researcher Dr. William C. Demand.
00:06:41The doctor recorded and monitored Randy Gardner's sleep activity.
00:06:45Gardner managed to stay awake for 11 days and 25 minutes.
00:06:51Your body eventually gets used to getting less sleep.
00:06:54Myth or fact?
00:06:56It's a myth.
00:06:57There are many studies proving that your body and especially your brain can't get used to sleeping less.
00:07:03Have you noticed that after a few nights of insufficient sleep, you begin to feel groggier during the day?
00:07:09That's your body trying to adjust to not getting enough rest.
00:07:12Long-term sleep deprivation affects your daytime performance, focus, and decision-making.
00:07:19Many grown-ups need 5 or fewer hours of sleep.
00:07:22Can it be true?
00:07:24Well, this one's easy.
00:07:26It's a myth.
00:07:27Experts from the National Sleep Foundation recommend that the average adult sleeps 7 to 9 hours per night.
00:07:33Some people have a genetic mutation thanks to which they wake up refreshed after a short night's sleep, but such
00:07:40people are an exception.
00:07:42One in 4 million.
00:07:44The ability to fall asleep in any place and at any time means you're a good sleeper.
00:07:49What do you think?
00:07:51Myth or fact?
00:07:53It's a myth.
00:07:54A good sleeper gets a proper amount of sleep and has a regular sleep schedule.
00:07:59Cats spend two-thirds of their life asleep.
00:08:02Do you believe that?
00:08:04This will probably come as no surprise.
00:08:07It's a fact.
00:08:08How many of the facts and myths did you guess correctly?
00:08:13How many hidden features are there in your car that you have never heard of?
00:08:18Most cars these days have everything color-coded under their hoods.
00:08:21It makes it way easier to know what you need to supervise between services.
00:08:27Like the dipstick, the oil cap, or the coolant.
00:08:31You can even have a look at the brake and washer fluid.
00:08:34Anything else that's black or gray, just leave it to the mechanics.
00:08:40Ever seen a snowflake light on the dashboard of your car?
00:08:44It's not there to let you know the winter holidays are coming if that's what you're thinking.
00:08:48It's actually a sensor that indicates the exterior ambient temperature.
00:08:53It gets activated and pops up the light whenever there's a road warning due to a sharp drop in temperature.
00:09:01It may sometimes even come on with an audio warning or a message on your dashboard
00:09:05to warn you that the roads may be getting icy.
00:09:08So you can either adapt the speed or change to the appropriate tires if necessary.
00:09:14Most cars come with added features for the summertime too, like those neat sun visors.
00:09:20Yours might have an added bonus you might want to check out.
00:09:23We all know they twist to help the driver out when the sun is not shining from the front.
00:09:28But some of them can also extend, so they can provide shade to a larger area.
00:09:34If you figure out your sun visor doesn't extend, there's a simple solution though.
00:09:40Buy a sun visor extender.
00:09:42You can even find them online.
00:09:44They work by being attached to your existing sun visors or windows for better shade coverage and visibility.
00:09:51Let's find some hidden features at home.
00:09:54It's not rocket science, but there is a wrong way to make ice in the freezer.
00:09:59And that's because you're probably not using the ice cube tray correctly.
00:10:04They come with that particular shape because you need to fill the trays until there's a layer of water on
00:10:09the top.
00:10:11This layer will help remove the cubes faster from the tray because it will crack when twisted and leave each
00:10:17cube poking out.
00:10:18You can then grab them in no time and enjoy your drink.
00:10:23If you find that the heat on your oven is too high or you need to cook some delicate dishes
00:10:28that require more control over the temperature,
00:10:31there's an easy way to adjust that.
00:10:34The knobs on your oven should come with calibration screws on their backs.
00:10:38Pop out the plastic knob and adjust it to your preferences.
00:10:43Be sure to disconnect the oven from any energy source before doing it.
00:10:48Do you know what your stove and your car have in common?
00:10:51They both have hoods that you can open if you need to have a peek or if they need some
00:10:56cleaning.
00:10:58If you look closely at the top of your kitchen stove, you will see two hinges located on the back
00:11:03corners.
00:11:05You'll be able to easily lift it up and clean out all the grime that's been stuck in there.
00:11:10Ever wondered why glue doesn't stick to the inside of the bottle?
00:11:14The answer is a bit more complex, depending on the type of glue.
00:11:18But the simple response is, well, it doesn't have any air in there.
00:11:24PVA glue contains some molecules called polymers and water.
00:11:29When the glue is out, the water evaporates, leaving just the sticky polymers behind.
00:11:35Things are more or less the other way around with superglue.
00:11:39It has a chemical that solidifies as soon as it hits water vapors in the air.
00:11:46Did you know Microsoft Word has a feature that you can use for references and a bibliography?
00:11:52It's not only helpful for keeping track of everything, but it also automatically formats all the information accordingly.
00:12:00If you like to surround yourself with as many houseplants as possible, here's an easy way to figure out if
00:12:06they need watering.
00:12:07Stick your fingers into its soil.
00:12:09It should give you a better idea than simply looking at the plant's surface.
00:12:14If you can reach 2 to 3 inches into the soil and feel it's dry, the plant most likely needs
00:12:20some hydration.
00:12:22However, this trick does tend to work better with smaller potted plants because of the limited depth.
00:12:28In any case, it's always best to research the plant's needs in terms of watering and sunlight before committing to
00:12:34a plant.
00:12:35And always be careful not to damage its roots.
00:12:39Be honest, you indeed have clothes you wear all the time and some that just sit there in the back
00:12:45of your closet that you've most likely forgotten about.
00:12:48Here's a neat way to figure out which one is which.
00:12:51For starters, you'll need to turn all of your hangers backwards.
00:12:55If you really feel like putting more effort into this project, you can wrap some pieces of electrical tape on
00:13:01the hangers and write the start date on each.
00:13:04After that, everything is pretty self-explanatory.
00:13:08Each time you wear a particular item, turn the hanger around, making it face forward.
00:13:14After 6 months or a year, all those items that have yet to be turned around should go to donations
00:13:20or yard sales.
00:13:22Another great way to use hangers to help you with your wardrobe organization is to use them for your scarves.
00:13:28They will be wrinkle-free, but you can also see them a lot better and have a clear view of
00:13:33the scarves you actually use and those you should let go of.
00:13:37If you're looking to increase the storage space in your wardrobe, especially when the season changes, go pick yourself up
00:13:44some vacuum-packed storage bags.
00:13:47After that, you just need to fold your garments or other pieces of laundry, like bedding or blankets for example,
00:13:54and place them in the bags.
00:13:57Turn on your vacuum cleaner, place the nozzle on the bag seal and remove all the extra air from the
00:14:03bag.
00:14:03It helps with reducing the storage size of clothes and keeps the clothes clean, dry and moth-free.
00:14:10Should you have an empty basket lying around and you aren't sure if you want to recycle it just yet,
00:14:15you can always repurpose it as a cool lamp.
00:14:18Wicker baskets work best for this.
00:14:21Just cut a small hole in the bottom of the basket and place a pendant-like kit there.
00:14:27You can even paint it manually or spray paint if you need it to be in a particular color.
00:14:32Another way to neatly repurpose things around the house is to use leftover cookie jars to store dryer balls, but
00:14:39the sky's the limit here.
00:14:41You can also use dryer sheets to remove dust from screens around your house, like computers, laptops, or TVs.
00:14:49These items are electrically charged, so they generally attract a lot of dust particles.
00:14:55Dryer sheets are made to reduce static cling, so they won't only remove the dust but also help keep it
00:15:01at bay for a longer period of time.
00:15:04Dryer sheets also help out if you're having a bad hair day, believe it or not.
00:15:08They can seriously help out taming flyaways whenever your frizz just gets out of control.
00:15:15Run one of those dryer sheets from the roots of your hair all the way down to the tip, and
00:15:19be amazed!
00:15:21If there's a particular type of soap bar you like the smell of and want to replicate that on your
00:15:26clothes too, pick up one of those bars to make a day's clothes fresher.
00:15:32Place it in a fabric and place it anywhere between your clothes.
00:15:35Your shirts should smell awesome every time you pick them up.
00:15:39You can also save on fabric softener.
00:15:43I don't know about your washing machine, but mine does love to jump, I'll tell you that.
00:15:48If yours tends to run out of its designated place, especially during those intense spinning cycles,
00:15:54it happens because it's not perfectly fixed to the floor.
00:15:58The good thing is that most modern washing machines can self-level since they come with a pair of legs.
00:16:03Just lift the back of the device off the surface area it sits on, and it will drop them,
00:16:10locking them into place once it's perfectly leveled.
00:16:18Okay, today I'll show you things you've never seen and tell you stuff you never knew.
00:16:23Wow, all in one video! What a bargain!
00:16:26For example, these soda found stations in fast food restaurants.
00:16:30We all see the nice side of it, but have you ever wondered where all this soda comes from?
00:16:35Let me take you behind the scenes.
00:16:38Ta-da!
00:16:38Turns out it's a pile of boxes with tubes.
00:16:41So when the drink runs out, the employees change the box and plug the tube back in.
00:16:47Okay, let's peek into a couple more places where we normally don't belong.
00:16:52This is, for example, what you will see if you cut the screen of a Mac open.
00:16:57And here's what's hidden behind the dryers in a public laundromat.
00:17:01Today, 4 out of 5 households in the U.S. have a dryer.
00:17:04But they weren't so widely accessible when they first appeared in the 1950s,
00:17:09because they were way too expensive for the average homeowner.
00:17:12Now, grocery shopping isn't an uncommon practice,
00:17:15and we all have walked past dairy fridges a million times.
00:17:19But have you ever wondered what's behind them?
00:17:22Turns out they're just shelves, and store employees stack the products from the other side.
00:17:27It makes perfect sense, but I never imagined it like this.
00:17:30Now, this photo shows what's behind the elevator button.
00:17:34Obviously, a bunch of cords.
00:17:36The buttons are all wired to a computer that manages the elevator.
00:17:40How does the computer know where the elevator is at a particular time?
00:17:44Well, there are several possible systems.
00:17:46But the most common one is a long vertical tape in the shaft with a series of holes.
00:17:52A sensor counts the number of holes that are passed, and that's how the location is determined.
00:17:57Okay, there are a couple of common things we all know,
00:18:01but the purpose of which remains a mystery to most.
00:18:04So let me share these secrets with you.
00:18:07Those metal rivets on jeans have been there from the very beginning.
00:18:11Jacob Davis, the iconic man who made the first pair of jeans,
00:18:15added copper rivets to places where pants are most likely to rip.
00:18:20Today, they have more of a decorative and distinctive purpose,
00:18:22since they are a traditional attribute of the jeans everyone knows of.
00:18:27Now, I'll bet you know there are extra loops on some shoes.
00:18:31No, they're not for sweat or ventilation.
00:18:33Those are extra loops for laces, just like other loops you use.
00:18:37But they're there to tie your shoe around the ankle to prevent your foot from moving aside.
00:18:43That's especially helpful if you're hiking and ascending and descending hills and trails.
00:18:48Now, have you ever noticed those half-belt thingies many coats and jackets have at the back?
00:18:53Turns out they first appeared on oversized military jackets,
00:18:57so the extra fabric could be collected on the back,
00:19:00and the person doesn't stumble when working.
00:19:02Today, those belts are only added for the sake of style and tradition.
00:19:07Most clothing items you buy come with a small bag of fabric or a button, or both.
00:19:12These are actually not useless.
00:19:15Buttons obviously can be replaced if you lost the original one.
00:19:18Pieces of fabric can serve two purposes.
00:19:21You can patch up the haul, but the main purpose is to provide you with a sample of cloth,
00:19:26so you can use it to test different washing products on it and see what happens to the fabric.
00:19:32Now, pom-poms on woolen hats.
00:19:34Did you know that sailors were wearing hats with pom-poms in the 18th century
00:19:39to protect their heads in case they accidentally whacked them?
00:19:43Regular people were wearing them in Scotland,
00:19:45and the color of the pom-pom signified the person's social status.
00:19:49People got back to wearing hats with those cute decorative items during the Great Depression.
00:19:54They're made of spare yarn, so it was a cheap way to decorate your hat.
00:19:58Now, if you haven't noticed, some sidewalks have little plates with bumps on them.
00:20:03Most people don't pay much attention to them, but they're very important for visually impaired people.
00:20:09It signals a slope that then leads to a crosswalk.
00:20:12Also, several patterns signal different things.
00:20:15Have you noticed that the icon of a gas tank on car dashboards has a little arrow next to it?
00:20:22Well, the arrow has a purpose.
00:20:23It points at the side of the car where the gas tank is located.
00:20:28Very useful for forgetful people, like me, who constantly wonder which side it is on,
00:20:33and also for those who drive rentals once in a while.
00:20:36The answer is right in front of your eyes.
00:20:38If you can't find the arrow on your panel, then the fuel hose on the icon indicates the side instead.
00:20:45Now, on the back of many makeup and hygiene products,
00:20:48you'll find this symbol with a marking like 6M, 12M, and 24M.
00:20:53This is the number of months this product can serve you before you should toss it out.
00:20:59You might know that whistles work perfectly fine even if they don't have that ball inside.
00:21:04And yet, they have it.
00:21:06But why?
00:21:06Even though there's a sound without the ball, the noise it creates is very flat,
00:21:11and it's not distinguishable enough.
00:21:14When the whistle has a ball inside, then it starts moving with every blow,
00:21:18indicating different pitches and making the noise more noticeable.
00:21:23Lollipop sticks have those squared holes on the end of their sticks for a reason, too.
00:21:27When the candy is put on the stick, some of it goes into the hole, fixating the candy part.
00:21:33This way, the candy ball or whatever shape is less likely to fall off the stick.
00:21:38Yeah, it's a bummer when that happens.
00:21:41Measuring tapes have that little metal stud on the end.
00:21:44Most people know that you can use it to stick it to the side of the surface you're measuring.
00:21:49But it's not the only cool thing about it.
00:21:51Look, there's also a small slot.
00:21:54And this slot can be used to hang it on a nail.
00:21:57Again, to free your hands and keep measuring.
00:21:59The bottom of the end of the tape has a ridged edge.
00:22:03It'll help you make a mark if you don't have a marking tool with you.
00:22:06Have you ever wondered why the tape's blade is curved?
00:22:09Well, it helps to keep it rigid when extended.
00:22:13Pay a closer look at the blade.
00:22:15Apart from numbers and markings, there are also black diamonds.
00:22:19Those are there every 12.2 inches, and they're useful for construction workers to space engineering joists.
00:22:27They can also be useful for you if you want to hang something heavy, for example.
00:22:31The diamond will mark the exact center of a stud, which is placed 16 inches apart from one another.
00:22:38And you can drill something to that center to make sure whatever you hang is safely attached.
00:22:44Now, most coins have ridges.
00:22:46And this is the legacy of the olden days.
00:22:49You see, back in the day, all coins were linked to a silver standard.
00:22:53The amount of silver used in the coin was proportionate to the value of the coin.
00:22:57So, the more actual silver was used to make the coin, the higher its value was.
00:23:03Hi-ho silver!
00:23:04Do you remember the Lone Ranger?
00:23:06Silver was the name of his horse.
00:23:08Eh, never mind.
00:23:09Anyway, all the coins had precious metal in them, and some people started shaving off a little bit of silver
00:23:16from it.
00:23:17It wasn't noticeable on one, but if done on several, people could get quite a bit of that precious metal.
00:23:23So, to prevent fraud, the edges were made with ridges for security reasons.
00:23:28So, if someone attempted to shave it off, the ridges would disappear, and no one would accept that coin anymore.
00:23:35Smart!
00:23:36Today, no one makes coins out of silver.
00:23:38The coins just represent the value.
00:23:40But the ridges are kind of a cultural heritage now.
00:23:43And finally, a typical plastic milk jug often has inverted circles on one or more of the sides.
00:23:50Not like alien crop circles, this dimple is there to make the jug more resistant and to prevent it from
00:23:57erupting in case the jug falls on the floor.
00:23:59The dimple gives some more space for the liquid to expand.
00:24:03Also, as the expiration date approaches, the microbes in the milk start to expel some gases.
00:24:08As there are more of them trapped inside, the pressure in the jug is rising.
00:24:13The dimple takes care of the expansion and prevents the jug from exploding.
00:24:17And the cows are utterly delighted that their hard work is not wasted.
00:24:27What's hiding inside Coca-Cola cans and regular household batteries?
00:24:32Why do magnets affect breakfast cereals?
00:24:35Do crosswalk buttons actually work, or are they just useless decorations?
00:24:40What does that USB symbol really mean?
00:24:44I'm not sure I know the answers to these and similar questions, but I'm eager to learn the truth together
00:24:50with you.
00:24:51Let's find it out.
00:24:53Coca-Cola cans have a secret few people know about.
00:24:57Here's a Coke can.
00:24:58Let's submerge it in a highly corrosive alkaline solution.
00:25:01The aluminum dissolves due to a process known as hydrolysis, and we can see a plastic liner inside the can.
00:25:09It's made from a polymer or epoxy resin, and serves as some kind of a protective barrier between the aluminum
00:25:15walls of the can and the rather acidic soda.
00:25:20Despite a popular myth, household batteries don't actually contain liquid.
00:25:24And if you accidentally cut them open, no toxic liquid will spill.
00:25:28Most of them are dry cell batteries, which are made of electrochemical cells.
00:25:33Those convert chemical energy into electrical energy.
00:25:37Larger batteries often house numerous small cells within them, too.
00:25:41Even Tesla vehicle batteries consist of multiple small cells.
00:25:45When combined, they easily provide the necessary voltage.
00:25:51Most toothbrushes have differently colored bristles, but they aren't just pleasing to the eye.
00:25:55Those bristles, often blue, have a functional purpose.
00:25:59They're called toothbrush indicators, and their colors fade as you use the brush.
00:26:03The American Dental Association recommends changing your toothbrush at least four times a year.
00:26:09And by getting paler, these bristles help you figure out when it's time to replace your toothbrush.
00:26:15You'll probably agree that there's no better snack than a pack of chips.
00:26:19Some are flat, others have ridges.
00:26:22Is it just aesthetics?
00:26:24Not really.
00:26:25The main purpose of those lines on some kinds of chips is to help with the distribution of spices and
00:26:30seasonings.
00:26:31In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
00:26:37Plus, the lines make chips crunchier.
00:26:41Now, this one might be a surprise, but some breakfast cereals are magnetic.
00:26:46That's because they're often fortified with iron in the form of a fine powder.
00:26:51Due to the added iron, cereal flakes get attracted to magnets.
00:26:55All this may sound kind of alarming, but in reality, the iron content in the flakes is minimal and doesn't
00:27:00pose any threat to your health.
00:27:03That clear fluid in gel pens is called the ink follower or stopper fluid.
00:27:08The gel in such pens contains pigment particles dissolved in a polymer solution.
00:27:13The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
00:27:18out.
00:27:20Without this transparent fluid, your gel pen wouldn't function.
00:27:24The fluid always stays in one position and doesn't get dissolved with the gel.
00:27:29Neither does it move backwards or flow out of the pen.
00:27:34Many pedestrian crosswalk buttons, namely in New York, are placebo buttons.
00:27:39They do literally nothing when you press them.
00:27:42Originally, they were functional after being introduced in 1964, but today, most of them don't affect traffic lights,
00:27:48which are programmed based on the real needs of the traffic flow.
00:27:52Why do such buttons even exist, then?
00:27:55It's a simple psychological trick, providing you with an illusion of control.
00:28:01You might have noticed that movie theater seats are almost always red.
00:28:06This choice isn't random.
00:28:07It has strategic importance, which is rooted in visual science.
00:28:11The thing is, red light has a longer wavelength.
00:28:14It means that it's the first color to disappear in low light.
00:28:17It allows the audience to concentrate better on the screen once the movie begins.
00:28:22Such a design choice enhances the viewing experience by minimizing distractions.
00:28:28Speed bumps are crucial for pedestrian safety.
00:28:31But at the same time, they can seriously increase car emissions due to the non-stop acceleration and deceleration they
00:28:38cause.
00:28:39To address this issue, some cities, like London, are testing fake speed bumps.
00:28:44Those are optical illusions painted on the road.
00:28:47They look raised from a driver's perspective, but in reality, they're flat.
00:28:52Authorities hope that this approach will slow down drivers without having a negative impact on the environment.
00:29:00Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
00:29:05That's because soda contains carbon dioxide.
00:29:08It's a gas that can expand once the bottle's heated.
00:29:11If there's no gap in the bottle, it can break because of the pressure building inside.
00:29:16Also, when you open your drink, the gases go out in the form of bubbles, making the drink overflow.
00:29:22The gap helps with this problem, too.
00:29:26The USB symbol, looking like a trident, has always sparked multiple speculations about its origin.
00:29:34One popular idea is that it represents Neptune's trident and symbolizes power and adaptability.
00:29:40But there's also a little bit less exciting theory.
00:29:43A man who claimed to have designed the symbol in the 1980s stated that it was supposed to represent connectivity.
00:29:49The large circle symbolizes a computer, while the attached shapes, the circle, the triangle, and square, stand for different outputs.
00:30:00The design of a tennis racket has a specific feature known as the throat.
00:30:05It's an open space below the head of the racket.
00:30:08This space isn't just for storing balls.
00:30:10It also improves the racket's aerodynamics by letting air pass through.
00:30:14It seriously reduces drag during swings.
00:30:19Speaking of tennis, tennis courts are usually built with a north-south orientation.
00:30:24It helps minimize the impact of the sun's position during the game, ensuring that neither player has the sun directly
00:30:31in their eyes.
00:30:33Look closely at a tram's overhead lines, and you'll see that its contact wires zigzag back and forth instead of
00:30:40going in a straight line.
00:30:41That's because all trams have pantographs attached to their roofs.
00:30:46The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
00:30:53To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
00:31:01As the tram moves, the pantograph slides along the wire, and it wears down evenly.
00:31:07Those cone-shaped water cooler cups?
00:31:10Their shape is intentionally designed to prevent users from setting the cups down.
00:31:15This allows employees to minimize the risk of spilling water on their desks around various electronic devices.
00:31:22Plus, less material is used to produce cone-shaped cups, which makes the process less wasteful and more cost-effective.
00:31:29It also kind of supports sustainability by encouraging people to drink their water quickly and dispose of their cups immediately
00:31:35after.
00:31:39Most suitcases have two zipper pulls, and it serves several purposes.
00:31:44First of all, if one zipper fails, the other can keep the suitcase closed.
00:31:49Even better, having two zippers allows you to have easier access to small sections of your suitcase without having to
00:31:55open it entirely.
00:31:58And finally, when you have two zippers, you can connect them with a padlock for increased security.
00:32:06Some plastic milk containers have dents on their sides.
00:32:09These dents serve several purposes.
00:32:12When milk spoils, it usually causes swelling and high-pressure buildup inside the container.
00:32:17That's when the dent pops out and doesn't let the jug blow up.
00:32:20Plus, if you decide to freeze the milk, it will expand like any other fluid.
00:32:25And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
00:32:34If you ever had a problem figuring out why fake pockets exist, you need to hear this.
00:32:40The main reason is that if a clothing item has a specific cut or shape, pockets may spoil it.
00:32:46They can alter the item's shape either in the warehouse or already on the retail rack.
00:32:51The solution?
00:32:52Getting rid of the pockets in key areas.
00:32:55Plus, fake pockets are obviously cheaper, and they don't get stretched out.
00:33:01The thermos wasn't actually invented to keep your coffee warm.
00:33:05It was made by a Scottish scientist who wanted a safe place to keep his chemicals at a stable temperature.
00:33:12So, he took two bottles, put the smaller one inside the bigger bottle, and vacuumed out the air between them.
00:33:21There's a dangerous dish that can poison you when prepared incorrectly.
00:33:25Everyday food like honey and cashew can be harmful too, in certain conditions.
00:33:30You should know these facts before you eat some products.
00:33:34Have you ever chewed the seeds when eating an apple?
00:33:37Then you know that unpleasant taste the seeds have.
00:33:40That's because of cyanide.
00:33:42Don't be alarmed yet.
00:33:43The seeds have a protective cloak covering them.
00:33:46That's why cyanide doesn't enter your system if you accidentally swallow the seeds.
00:33:51Better be cautious though.
00:33:52Even small doses of cyanide can result in rapid breathing and more extreme and unpleasant results.
00:33:59Another danger lurking in your kitchen is potatoes.
00:34:03The ones with sprouts and green spots.
00:34:05Cutting off the green parts or sprouts solves the problem only visibly.
00:34:09The toxic substance called glycoalkaloid may have already spread through the whole potato.
00:34:15This substance turns some parts of a potato green for some reason.
00:34:19It's a sign for you.
00:34:21Eating this kind of potato can cause nausea, headaches, and other consequences.
00:34:27Are you a bubble tea fan?
00:34:29Then maybe you're familiar with cassava, a.k.a. tapioca.
00:34:33This is a root veggie, and it's cultivated in South America.
00:34:37It's also often used to make cakes and chips.
00:34:40It can be either sweet or bitter.
00:34:42It's common for root and tuber varieties of cassava to contain toxins.
00:34:48Tapioca must be prepared properly before you consume it.
00:34:51If it's served incorrectly or eaten raw, the consequences are pretty serious.
00:34:56But when it's processed correctly, it's delicious and safe to eat.
00:35:02Elderberries are known as a supplement to boost your immune system and help your body fight a cold or the
00:35:07flu.
00:35:08This medicinal plant needs to be handled and prepared with care, too.
00:35:13If you eat unripe berries, they can do more harm than good.
00:35:17Here comes lectin and cyanide.
00:35:19These chemicals can cause stomach problems, for instance.
00:35:23This one makes me sad more than any other thing on the list.
00:35:26And this list includes a lot of healthy products.
00:35:29Anyway, here I spell it out.
00:35:32Popcorn
00:35:32There are many studies saying that microwave popcorn is harmful for you.
00:35:38First, you consume the chemicals used in packaging.
00:35:41There are also flavoring additives that aren't healthy.
00:35:45Now, remember that moment when you open the bag and hot popcorn-smelling air goes up into your nose?
00:35:51It can lead to irreversible lung damage.
00:35:53For instance, there's a diagnosis named popcorn lung.
00:35:57A chemical used to provide microwave popcorn with its buttery flavor is related to that diagnosis.
00:36:04What can you do?
00:36:05Choose other packaging options or invest in an air popper.
00:36:09Air-popped popcorn has only 90 calories and less than 1 gram of fat.
00:36:15Yay!
00:36:16Number 6 is honey.
00:36:18Honey is a sweet liquid made by…
00:36:21I'm joking.
00:36:21But do you know that natural honey is dangerous to eat if the amount is more than a teaspoon?
00:36:27It has a toxin with a hard-to-pronounce name.
00:36:30To get rid of this toxin, honey has to go through a pasteurization process.
00:36:34Let's move on to cherry pits.
00:36:36If you don't chew or crunch them, you'll probably be fine.
00:36:40Yet, keep in mind that these pits contain prusic acid, and this stuff is poisonous.
00:36:46What about ackee fruit?
00:36:48It's the national fruit of Jamaica, and it turns out unripe ackee contains a poison called hypoglycem.
00:36:55Ackee fruit must be fully ripe if you want to eat it.
00:36:58In other words, this fruit should open up by itself.
00:37:01Once it's ready to be picked up, it'll split wide open.
00:37:05No to the highly toxic pink flesh or black seeds, and yes to the delicious creamy pulp near the seeds.
00:37:12Eating this fruit incorrectly can cause Jamaican stomach sickness.
00:37:17Fugu is the Japanese word for puffer fish, and the dish prepared from it.
00:37:22What's interesting about this dish is that it can be the last dish in your life if you don't prepare
00:37:28it properly.
00:37:29This fish contains a very powerful toxin that's very dangerous to humans.
00:37:34A single fish has enough poison to harm 30 people.
00:37:38Because of this, Japanese chefs undergo years of training to get a special license.
00:37:43Despite all precautions and preparations, fugu still sometimes becomes the last meal for some people.
00:37:50Would you take that risk?
00:37:52Perfect ciders, cashews.
00:37:55They can also be very risky to eat when they're raw.
00:37:58You probably get cashews from stores with raw cashew labels, but they aren't 100% raw.
00:38:03Before they find their spots on the shelves, they're processed with steam to remove a toxin called urushiol.
00:38:11Cashew shells contain this toxin.
00:38:13What would happen to you if you ate these nuts raw?
00:38:16A dangerous allergic reaction if you have a tendency to allergies.
00:38:20This depends on your sensitivity to poison ivy.
00:38:25Speaking of raw food, raw kidney beans are risky too.
00:38:29They contain a toxin called lectin.
00:38:31This one can give you stomach aches and other digestion-related issues as a bonus.
00:38:36All you need is to swallow 4 to 5 raw beans to experience these side effects.
00:38:42Red beans are rich in plant-based protein, essential vitamins, and minerals.
00:38:47Cook them correctly to enjoy these goodies.
00:38:49For this, keep dried red beans on the stove for at least 10 minutes.
00:38:54Boiling them for a shorter time and at a lower temperature can actually increase their toxicity.
00:38:59Beans can become even more toxic than if they are consumed raw.
00:39:03So yeah, a minimum of 10 minutes at high temperatures.
00:39:07Eating too many untreated bitter almonds can cause many unpleasant symptoms and health issues.
00:39:14Rhubarb leaves are a bit tricky too.
00:39:16You can eat the stock, but don't munch on the leaves.
00:39:19The leaves contain oxalic acid, which ties to calcium.
00:39:24This makes it harder for the body to absorb the needed amounts of calcium.
00:39:28Mushrooms.
00:39:29For plenty of people, pizza and pasta wouldn't be so great without mushrooms.
00:39:34We all know that mushrooms are kinda unpredictable, especially if they grow in the wild.
00:39:39Here are two of the most dangerous ones.
00:39:41The death cap and the destroying angel.
00:39:45Starfruit is a risky choice for people with sensitive kidneys.
00:39:49If you're one of them, you might want to keep this fruit out of your meals.
00:39:53Regularly functioning kidneys can filter out the toxins starfruit contains.
00:39:58Otherwise, the toxin will hang around and cause some problems there.
00:40:01The next product on the list is nutmeg.
00:40:05If you find that nutty flavor super nice like me, hear me out before adding it everywhere.
00:40:10Small amounts of nutmeg are fine and healthy.
00:40:13But if you, let's say, eat spoonfuls of nutmeg, it can cause problems.
00:40:18Even with two teaspoons.
00:40:20Knock, knock.
00:40:21You get poisoned.
00:40:23Canned tuna can be a lifesaver.
00:40:25It's not pricey.
00:40:27It's a good source of protein.
00:40:28And with its help, you can prepare a delicious meal quickly.
00:40:32No cooking, just lettuce, bread, and a few more ingredients.
00:40:36There you go.
00:40:37How about three to five times a week?
00:40:40And you might experience a side effect called mercury poisoning.
00:40:44Now, this is related to how much and what type of food you consume.
00:40:48Canned tuna contains mercury, and that's why eating too much of it can lead to mercury poisoning.
00:40:54Medical advisors say that every kind of fish has some level of mercury.
00:40:59But that level differs from one species to another.
00:41:02For example, canned tuna has relatively high levels of mercury.
00:41:07Obviously, seafood is a great source of omega-3 and other things that are essential to our brain and good
00:41:12health.
00:41:13To stay safe, experts advise people to choose low-mercury seafood.
00:41:18Here's an interesting fact related to this.
00:41:20To get the most omega-3 fats from your canned tuna, choose water-packed fish instead of oil-packed.
00:41:27In oil-packed cans, the oil mixes with some of the tuna's natural fat.
00:41:32You open the can and drain the oil, and some of the fish's omega-3 fatty acids also get drained.
00:41:38But water and oil don't mix.
00:41:41Water-packed tuna won't lose its omega-3 fats.
00:41:44You can add some oil and dressing after you open the can.
00:41:51Have you ever wondered what these extra holes at the top of your running shoes are for?
00:41:55They're designed so that you can tie the shoes in multiple different ways.
00:41:59That's useful when you want to compensate for things such as a bad stride or even a damaged toe.
00:42:06Plus, you can change the look of your shoes the way you prefer.
00:42:12Many people use a dust jacket of their book as a bookmarker.
00:42:16No problem with that.
00:42:17It will save your book from bent page corners.
00:42:19But the primary purpose of a dust cover is to keep the book safe from distortions.
00:42:25For instance, if you spill juice or drop some of the food on your book while reading it.
00:42:31The tic-tac dispenser has this little groove on its top, so you can dispense only one tic-tac at
00:42:37a time.
00:42:38Even though, let's be honest here, nobody does that.
00:42:41Most of us just spill a whole bunch at once, and then we wiggle all those extra tic-tacs back
00:42:46in.
00:42:48Those rubber bumps you see between the tire treads are there for your safety.
00:42:52The raised edges tell you what the minimum height of your tread is.
00:42:56If the bump and the edges are even, it's time for you to visit the tire shop as soon as
00:43:01possible.
00:43:02But if the bumps are well beneath the level of the edges, you're good to go.
00:43:08What about that black grating on the microwave window?
00:43:11It's something called a Faraday shield.
00:43:13And it's there to prevent microwaves from getting away and turning the entire room into a Faraday cage.
00:43:20If the microwaves escape, your meal won't cook properly either.
00:43:24So yep, the cage is not there to make it difficult for you to see your meal while it's cooking.
00:43:28It's keeping the electromagnetic energy inside.
00:43:34How about a wrench-compatible screwdriver?
00:43:36Cover your screwdriver with the end of your wrench and you can increase its torque.
00:43:40That's why the head of your screwdriver is designed the way it is.
00:43:44When you have odd angles, you can use this strategy.
00:43:49You've probably heard those myths, the blue side of the eraser can erase the pen.
00:43:54False.
00:43:54Its purpose is to erase a pencil.
00:43:57But in case you're writing something on heavier paper.
00:44:00The blue side can remove smudges you see after using the pink eraser too.
00:44:06Have you ever wondered why oranges in supermarkets mostly come in the red mesh bag?
00:44:12It's a trick to make this food look more orange and encourage you to make a purchase.
00:44:16An extra tip.
00:44:18Don't throw away the mesh bag.
00:44:19Tie it up so you can have a small pot scrubber to clean your sink, kitchen, appliances, and dishes.
00:44:28You can see golf balls don't have a perfectly round shape.
00:44:31Their surface is covered with many little dimples, something golf balls didn't always have.
00:44:36At one point, experienced golfers started noticing how through time,
00:44:41older balls with imperfections, such as nicks and bumps, could travel further.
00:44:47Such things create turbulence in the air around the golf ball, which eventually reduces drag.
00:44:53So, manufacturers started producing balls with dimples so they could go farther and faster.
00:45:01You might have noticed that sometimes there are ridges in toothpick tops.
00:45:04It's more hygienic because when you break that off, you can prop the toothpick up on it,
00:45:09and it won't touch anything.
00:45:13Another safety feature you'll find, this time in your car, is a tab on your rearview mirror.
00:45:19With it, you can change the position of the mirror,
00:45:22so you don't get blinded if there's a car behind you with its high beams on.
00:45:26So, this little tab helps you control the glare of lights coming from behind.
00:45:30This feature showed up in the 1930s, but in the early 1970s,
00:45:35it became a part of standard equipment in most trucks and cars.
00:45:40Do you see that tiny hole on your iPhone right next to the rear-facing camera?
00:45:45It's a microphone, and it's there so your phone can record sound as you turn your camera around.
00:45:53Some cables have a thick cylinder towards the end of the cord.
00:45:57It's called a ferrite core, or a choke.
00:46:00It's a magnetic iron oxide that stops high-frequency electromagnetic interference.
00:46:05For example, you know that annoying static noise you get if you bring your phone too close to a speaker?
00:46:12This interrupts your call, which is why cable cords with big cylinders are pretty useful,
00:46:16because they prevent these things.
00:46:20Do you know why nearly all luggage bags and backpacks have two zippers?
00:46:24It's way more convenient and easier to open in that way.
00:46:28But not just that.
00:46:29You can also lock these two zippers together to keep the stuff inside your bags safer.
00:46:36You know how toilets at public spots like malls have those big gaps at the bottom?
00:46:41It's primarily for better circulation of air.
00:46:44This type of door also makes it easier to clean the toilet,
00:46:48or check if it's occupied if you're standing in line.
00:46:51Other than that, if you get stuck there and the lock gets broken,
00:46:55you still have a way to escape.
00:46:57You can just crawl out.
00:47:00Ever notice those plastic end caps on utility knives?
00:47:04And they also have scales on them, which indicates you may use them multiple times, but with sharp edges.
00:47:19If you've ever taken a moment to examine a regular grocery cart, especially their fold-out section, you probably noticed
00:47:27those metal loops jutting out.
00:47:29They're designed to protect the items you carry in your cart.
00:47:33You can use them to hang bags with soft items.
00:47:37You don't want to accidentally squish with heavier products, like bread, or easily breakable things, like eggs.
00:47:45Many coffee mugs come with curved notches on their bottom.
00:47:49When you're washing your mugs, put them against the rack at an angle in your dishwasher.
00:47:53This way, the water won't pool in there, so your favorite cup will be completely dry by the time you
00:47:58take it out of the dishwasher.
00:48:01If you're a McFlurry fan, you've probably noticed there's a square hole in the handle of the spoon.
00:48:07It's there so you can attach it to the special machine that mixes the ice cream and your favorite toppings
00:48:12together.
00:48:14The machine has a bar that slips into this square-shaped spoon and then thoroughly stirs it.
00:48:19And you get the spoon so they can minimize the mess during the process.
00:48:24Quite neat, wouldn't you say?
00:48:27A regular milk jug has a dent on one side.
00:48:31Some might see it as a random design decision, but a dent has several purposes.
00:48:36One of them is to get bigger if there's a gas buildup.
00:48:40This happens when your milk is spoiled.
00:48:42So you don't even have to try to check this out.
00:48:45Also, the dent is there so the jug doesn't burst if you accidentally drop it.
00:48:50The dent allows the expansion space that deals with the sudden pressure that happens when you drop the jug.
00:48:58Dental floss.
00:48:59Sure, it's important for your dental health and it's easy to assume what you do with it.
00:49:03But dental floss is great in the kitchen as well because it's a very precise cake slicer.
00:49:09Way better than a regular knife.
00:49:14Most kitchen shears have a serrated opening right there at the center where the blades and handles meet.
00:49:20It's something you can use to trim difficult herbs such as rosemary, thyme, or chives.
00:49:26Because of this opening, you don't need to pick the leaves off by hand.
00:49:29But de-stem them in one motion.
00:49:33The majority of gelatin containers or single-serving yogurts come with a tinfoil lid.
00:49:38And in most cases, you can use this covering as a disposable spoon.
00:49:43Just peel away the covering and after a couple of simple folds, you'll have a perfect little spoon for your
00:49:49midday snack.
00:49:51You just spent the entire morning running errands up and down the street.
00:49:55And you finally stopped to treat yourself to a cup of coffee.
00:49:59You enter the nearest coffee shop, place your order, and notice that actually you really need to use the bathroom.
00:50:06It's a regular-looking public one with multiple stalls.
00:50:09As you pick yours, the one in the middle, you get inside and your mind starts to wander.
00:50:15Why on earth do bathroom doors have a half-inch gap between the door and the lock?
00:50:19And why on earth do they have a huge gap between the door and the floor?
00:50:24Can we have a drumroll for this moment, please?
00:50:27Well, my friend, there is not only one specific reason why public bathroom doors have so many gaps in them,
00:50:33but rather several.
00:50:35Public toilets are designed to make people spend as little time there as possible.
00:50:39You aren't supposed to feel comfortable or at home.
00:50:42So the design would have to reflect this notion.
00:50:45Here come the gaps.
00:50:47In some bathrooms, gaps are so big that users may even feel self-conscious about doing their business out of
00:50:54preoccupation that the rest of the people standing in line will see them.
00:50:58Then there's the matter of pricing.
00:51:01Making custom doors can be a heavy burden for the people building public toilets.
00:51:05This would mean understanding exact measurements so that doors would always fit the mold of the stalls it's supposed to
00:51:11be installed into.
00:51:12Now, not all the gaps in public bathrooms are necessarily the same size.
00:51:18They may vary, even if this variation is small and often unnoticeable.
00:51:22So these gaps actually help to reduce the margins of errors and to turn production more cost-effective for the
00:51:29people financing them.
00:51:31In case a door comes wider or more narrow than it should, the gap regulates the differences and allows for
00:51:37their installation anyway.
00:51:38There is also the case of air circulation.
00:51:41The last thing you want to do in a public bathroom is to trap odors.
00:51:46So you need a little space under and between the doors to allow the air to flow.
00:51:51Finally, the gaps are a big safety measure.
00:51:53It can always allow for people on the outside to see if someone inside a stall isn't feeling too okay
00:51:59and maybe need some help.
00:52:02And what about that extra hole in the upper part of the sink?
00:52:05It has a name in everything, the overflow hole, and it's designed to keep the sink from flooding.
00:52:11So in case someone forgets and keeps the faucet going for too long, or the sink gets clogged and water
00:52:17can't drain down from the main drain hole,
00:52:20the overflow hole comes in to save the day.
00:52:23Let's say it buys you a little time before you have the entire bathroom floor flooded.
00:52:27Have you ever noticed how satisfying closing the door of a car can be?
00:52:32Car manufacturers devote a great deal of time to designing these sounds.
00:52:36Studies have shown that they create a perceived sense of quality in the buyer.
00:52:41It all begins with the primary material.
00:52:43While older cars used to be made with heavier materials, car doors nowadays are produced with lighter tin,
00:52:50which can make a rather unpleasant metallic sound once you shut them closed.
00:52:54So car companies employ sound engineers to ensure that there is the exact amount of foam, mats, and tin in
00:53:01a car's composition
00:53:02to make the most comforting sound possible.
00:53:05And what about those tiny dots on the top of your car's front window?
00:53:09The pattern of these little black dots minimizes distractions for your eyes.
00:53:14This black part, also known as frit, normally gets warmer than the clear parts,
00:53:19which prevents the windshield from deforming.
00:53:21And no, the tab under your rearview mirror is not made only for the purpose of hanging fluffy dyes
00:53:27or aromatic-pleasing air fresheners.
00:53:30It's actually a switch that allows you to adjust the position of the mirror, depending on the time of day.
00:53:35Flip it one way, and it's the daytime driving mode.
00:53:38Flip the other, and you're ready to drive safely during nighttime
00:53:42as it tones down the glare coming from headlights of the cars behind you.
00:53:46Next time you head out to the supermarket, make sure to keep this in mind.
00:53:50In case you don't have a coin to unlock these shopping carts, there is a well-kept secret that can
00:53:55help you out.
00:53:56If you have your house keys on you, check for a rounded key head.
00:54:01If you happen to find one, try using it to unlock the cart.
00:54:04It should fit perfectly in there, replacing the need to carry coins around.
00:54:08Because, if we're being honest, who still has them?
00:54:12Elevators.
00:54:13If you want to ride them on your terms, and your terms only, make sure to try something out.
00:54:18Most elevators have a secret button combination you can use to skip all the other selected floors
00:54:23and go directly to the one of your choosing.
00:54:26This might work out, especially on those days when you've pressed 13.
00:54:30But you wanted to press 33.
00:54:32On most elevators, this works once you simultaneously press the closed door button,
00:54:37together with your floor number.
00:54:39This should help you get to your floor without stopping.
00:54:42Some elevators require you to double-press the selected floor numbers,
00:54:46as double-pressing will often cancel the previously made request.
00:54:50While other elevators require you to hold the open door button
00:54:54and then double-press the buttons of the floors you'd like to cancel.
00:54:57Now, to stay out of trouble, it's best not to cancel the floors of the other people in the elevator.
00:55:03They won't take it kindly.
00:55:05Also, keep in mind that there are elevators that might not have this function.
00:55:09Now, for honey lovers out there, go ahead and raise your hand.
00:55:12If your pot of golden honey is crystallized, know that it is actually a good sign.
00:55:18Crystallized honey means that it hasn't been pasteurized, which means better product quality.
00:55:23With a decrease in temperature, the natural ingredient of honey, also known as glucose, will make it crystallize.
00:55:30Now, try making the best of it.
00:55:32To add some texture to your oatmeal or toast,
00:55:35add a layer of crystallized honey and enjoy nature's sugar.
00:55:39And if you don't like crystallized honey, plop it in the microwave for a minute or two.
00:55:43Ah, winter and fall.
00:55:46You know what this means, right?
00:55:47Sweater weather.
00:55:48But there's nothing more annoying than wearing your beautiful wool sweater
00:55:52and itching yourself all the way through it.
00:55:55Actually, I can be more annoying than that, but let's talk about itchy sweaters.
00:55:59To keep this from happening again, here's the secret.
00:56:02Turn your sweater inside out and soak it in cold water.
00:56:06Add two or three tablespoons of vinegar and let it sit for a while.
00:56:10Then, drain the water.
00:56:12Now, while the sweater is still wet, massage a generous amount of hair conditioner into the fibers of the wool.
00:56:18After letting it soak in the hair conditioner for about 30 minutes,
00:56:22gently press the excess water out of the wool and leave it to dry flat on a towel.
00:56:27There you go!
00:56:28No more itchy sweater.
00:56:30Any fast food restaurant you go to will hand out small paper cups
00:56:34for customers to fill with their ketchup, mustard, or barbecue sauce.
00:56:38But if you're eating some chicken nuggets or trying to dip your burger into the cup,
00:56:43there's always that bit of sauce that seems impossible to reach.
00:56:47Next time, try unfolding the cup.
00:56:49It'll turn into a small paper plate, and this way, you'll get all the ketchup you poured in the first
00:56:55place.
00:56:56Padlocks used in outdoor environments should be clean and lubricated every three months.
00:57:02Regular lubrication will help prevent padlocks from freezing in cold weather conditions.
00:57:07Look for the tiny hole on the bottom of the lock.
00:57:10Then, pour oil into it, and there you go!
00:57:12It opens again!
00:57:14One thing we often neglect is a point in an ointment cap.
00:57:18Yeah, these pointy surfaces were designed to help us break the tinfoil protection of the ointment tube.
00:57:24You just turn the cap over and break the ointment seal with its own cap, and there you go!
00:57:30After a long day of work, all you really need to do is a bubble bath.
00:57:34You turn on the hot water and let it run for a few minutes.
00:57:37You might even light a candle and pour some essential oils into the water.
00:57:42Then, in comes the liquid soap.
00:57:44You stir the water until the entire surface of the tub water is crammed with bubbles and make your way
00:57:50in.
00:57:51The bubbles in a bubble bath have a fundamental primary function.
00:57:55Their job is to preserve the water's temperature, just so you can have warm water for longer.
00:58:01Do you have sweaty feet?
00:58:02Weird question, I know.
00:58:04But if you're one of these people, here's some good news.
00:58:07All is not lost.
00:58:09Try putting a dry teabag inside your shoes and storing it in a dry place for a while.
00:58:15The teabags will absorb the humidity and the smell off the soles of your shoes.
00:58:19So, here I am thinking, shouldn't we have learned these things in school?
00:58:23Well, either way, if you learned something new today, make sure to tell us about it in the comments below.
00:58:36If you ever find yourself stuck in the trunk of your car, stay calm.
00:58:41All cars are supposed to be equipped with an emergency latch to help open the trunk from the inside in
00:58:47the unlikely case it happens.
00:58:49These latches are so well thought out that they can be opened by people of all ages.
00:58:54More so, handles are designed to glow in the dark, too.
00:58:57You can even pull them with a mouth if there's not enough wiggle room to use your hands.
00:59:02Never mind how you ended up in the trunk in the first place.
00:59:05Moving on.
00:59:06If you're ever working with needle and thread, remember, you don't need to stick the needle directly into the spool.
00:59:12You may end up losing the needle altogether.
00:59:15Not to mention, you can easily hurt your fingers.
00:59:18A lot of modern sewing kits these days come with a designated place for safeguarding the needles.
00:59:24It's located at the bottom part of the thread spool.
00:59:26You'll just need to pull it out.
00:59:28It's even made to hold multiple sewing needles at a time.
00:59:32Disposable ballpoint pens come with a little secret of their own.
00:59:36Did you ever notice that in some of them, there's a small hole in the plastic part?
00:59:41It's actually a rudimentary ventilation system.
00:59:44It's supposed to let the ink easily make it to the tip of the pen.
00:59:49Okay, I know it's in the name, but you really don't need to shake the seasoning shaker to get any
00:59:54product out.
00:59:55Don't believe me?
00:59:56Hey, you're not the only one.
00:59:58Go grab your favorite seasoning bottle out of your pantry.
01:00:01If it has one of those removable plastic caps, it's perfect for the experiment.
01:00:06Instead of shaking the bottle, try holding it from the plastic cap while it's upside down.
01:00:12Now, gently twist the bottle from side to side and, before you know it, you get some gorgeously flowing seasoning
01:00:19without having to wiggle the shaker and make a mess all over the stove.
01:00:23On the same note, most salt and pepper shakers should have ridges on the bottom of the glass portion.
01:00:30In case you get any seasoning stuck in there, place the bottom of the salt shaker against the bottom of
01:00:36the pepper shaker and wiggle it around so the ridges click with each other.
01:00:40The seasoning should easily pour out now without you having to open the bottle.
01:00:45In colder weather, you often have so many clothing layers on you that you can hardly feel the purse or
01:00:51back straps on your shoulder anymore.
01:00:53Not to mention how fast they can slide off.
01:00:56Some jackets come with a built-in solution for that, in the form of a small tab on the shoulder
01:01:01with either a hook or a button.
01:01:03It's meant to be opened and closed comfortably, so you can keep your purse in place at any time.
01:01:10You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
01:01:16But you can use your vegetable peeler for chopping fine strips of onion as well.
01:01:21Just cut the onion into quarters vertically and then start slicing.
01:01:25This might also help out with those embarrassing onion tears.
01:01:30Most people miss this one, but should you ever have a closer look at your toothpaste tube, you will surely
01:01:36see some sort of coloring there, either a dot or a block.
01:01:40Colors can vary.
01:01:41They can be black, green, red, or even blue.
01:01:44These color spots are actually meant to help the assembly machines back at the toothpaste factory.
01:01:50They recognize when and where these machines need to cut the toothpaste tubes and proceed to fold them for packaging.
01:01:56For most types of footwear, if there's anything that seems a bit out of place, always know that it's there
01:02:02for a reason.
01:02:03Most manufacturers don't put extra items on shoes just for fun.
01:02:07It would definitely be a waste of time and resources.
01:02:11For footwear, like boots, for example, there's often a small loop at the top back of the shoe.
01:02:16It's there to help you when you need to put the shoe on, since you can quickly pull on it.
01:02:21Plus, you can also hang the shoes somewhere, most likely to dry, since most boots are meant to be worn
01:02:27in the colder weather.
01:02:29Now, I've been guilty at least once of overdressing with a bunch of layers, just so I won't need to
01:02:35jam everything in my check-in bag.
01:02:37But does it become a problem when you actually have to get seated?
01:02:41What do you do with your coat or your jacket?
01:02:43Well, have a closer look next time you board a plane on the seat in front of you.
01:02:48The hook that keeps the tray table upright can double as a jacket hook.
01:02:53As long as you don't need to have any meals while in the air, you're good to go.
01:02:58Now, most mascaras expire within 3-6 months, I'm told, depending on the manufacturer.
01:03:04But you can help speed up that process if you're not careful enough.
01:03:08Continuously pumping the mascara wand, trying to mix in the product, actually pushes more air into the tube.
01:03:14This can make it dry much faster, and you evidently won't get the desired results with it anymore.
01:03:21There's an easy way to check if your mascara is still good enough to use.
01:03:25If you don't hear a popping noise when you take the brush out, you may very well need to go
01:03:30get yourself a new mascara tube.
01:03:33Now, I know we're living in the era of Bluetooth-connected devices.
01:03:37But for better quality sound, they still recommend using headphones that connect via audio jacks.
01:03:44Remember seeing black ridges on those jacks?
01:03:46They aren't there just to make them fit when you plug them into your phone or laptop.
01:03:50Made out of a special insulating material, these bands are meant to guard the wires when sound is being transmitted.
01:03:58Based on the number of bands, you can figure out which end goes where.
01:04:02Some empty space under noodles in a cup doesn't mean the company producing them wants to cheat you out of
01:04:08a full portion.
01:04:09No, no.
01:04:10It's a manner of keeping the noodles intact during their transportation.
01:04:13It also helps with the circulation of hot water that is poured over the products before you can enjoy them.
01:04:20The V-shaped neckline was initially designed to serve a bunch of objectives.
01:04:25First, as a way of prolonging the life of the garment that would maintain its shape over the years.
01:04:30It's also there to fit your head through the shirt in case it needs some stretching.
01:04:34This way, it ensures a snugger grip around the neck.
01:04:38Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
01:04:43Now, it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket with an additional mysterious
01:04:50pocket on the right side.
01:04:52Turns out, this pocket was used by men to easily reach their train tickets, since most of them had to
01:04:58travel to work every day.
01:05:00It helped them keep their jacket buttoned up, but also benefited from the use of a pocket.
01:05:05Now, it's only added as a decoration, and it doesn't serve an actual purpose anymore.
01:05:11Speaking of things we don't use these days, or at least for their initial purpose,
01:05:16did you know Play-Doh was originally a cleaning product?
01:05:19In the 1920s, the market was in need of a product that could help them wipe the wallpapered areas around
01:05:26coal-burning furnaces.
01:05:27The recipe for what we now know as Play-Doh was thus invented.
01:05:32It was manufactured in white only, and was supposed to clean wallpaper by being rolled back and forth over the
01:05:38dirt.
01:05:39It was only later, in the 1940s, that new products for cleaning wallpaper were brought up,
01:05:44and Play-Doh was redirected toward another area of the market.
01:05:49Now, while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean out the
01:05:55toaster?
01:05:56Well, not anymore, since I recently found out that toasters have a slide or a panel at the bottom
01:06:02that helps get rid of all those annoying breadcrumbs easily.
01:06:08Now, there used to be a time when you could only have access to video games
