00:00:00You know what? Onions can help fight off the flu.
00:00:03Hmm. And apparently they can do it in various ways.
00:00:06Like you can put them in your socks,
00:00:08which somehow transfer their disease-fighting abilities through your feet.
00:00:12Or you can drink onion-infused water to treat or prevent illnesses like colds or the flu.
00:00:17Well, unfortunately, these are all false beliefs.
00:00:21When it comes to directly combating cold or flu viruses,
00:00:24onions are unlikely to have a super impact.
00:00:27But overall, they're good for you.
00:00:29At the same time, onions do have a high concentration of quercetin.
00:00:33It's a pigment known for its potential anti-inflammatory properties.
00:00:39The correct way to open a new deodorant is by manually prying the top off.
00:00:44Nope.
00:00:45Removing the cap from a new deodorant stick involves twisting it.
00:00:48This move triggers the mechanism to push the safety cap off.
00:00:52This method helps avoid the hassle of manually prying the lid off,
00:00:56leaving deodorant residue under your nails.
00:00:59Now, what about the ideal time for using deodorant?
00:01:03You might think it's in the morning before you leave the house.
00:01:06But the optimal time to use deodorant is in the evening.
00:01:09At this time, your body temperature is cooler and your underarms are less moist,
00:01:14providing a greater opportunity for the deodorant to work effectively on your skin.
00:01:19Applying deodorant in the morning is still okay for those people who don't suffer from excessive sweating.
00:01:24So, if you sweat a moderate amount, there's no reason to change your daily routine.
00:01:30Now, keeping your shower curtain inside or outside the tub is a choice.
00:01:34But, apparently, putting the shower curtain inside the tub reduces splashing and prevents water from escaping.
00:01:40The decorative cloth curtain belongs on the outside, whereas the plastic one should be on the inside.
00:01:46I mean, the whole idea is to prevent splashing water.
00:01:50Now, watering your plants on scorching hot days harms them.
00:01:55Rain showers occur during the summer season all over the world, and plants easily survive in these conditions.
00:02:00At the same time, when you water your plants on hot days, a substantial amount of liquid might evaporate before
00:02:07it can effectively benefit the plants.
00:02:09It's worth noting that this might be different for some sensitive indoor plants, such as African violets.
00:02:15It can result in leaf damage if you pour very cold water directly onto their leaves.
00:02:21Now, let's continue with another garden-related thing.
00:02:24Tree roots only reach as far as the outer edge of tree branches.
00:02:28Myth or fact?
00:02:29Well, it's a misconception.
00:02:32The root systems of many trees can extend well beyond the diameter of their crowns.
00:02:36For instance, magnolia trees can have roots that reach nearly four times their crown diameter,
00:02:42while the roots of red maple trees can exceed their crowns by up to three times.
00:02:48It's easier to shuck corn before it's boiled.
00:02:50Well, in the past, before the invention of modern cooking methods, many recipes involved pre-shucked corn.
00:02:57However, you can still grill it with or without the husk when it comes to recipes like grilled corn.
00:03:02A recommended technique is to partially shuck the corn, leaving only a few layers closer to the cob still attached.
00:03:09This method retains moisture while also providing appealing char marks on certain kernels.
00:03:16Alternatively, you can cook whole, unshucked ears of corn in the microwave or by boiling it, if you prefer.
00:03:24Moving on with everyday items you've been storing wrong.
00:03:28Take eggs, for example.
00:03:29Leaving them in the fridge door is good for them, right?
00:03:32No.
00:03:33This can lead to a rollercoaster of temperatures every time you grab a snack.
00:03:37As for nuts, they're happier in the fridge.
00:03:40He can make them go all wonky, especially if they're the kind with lots of good fats.
00:03:44So, keeping them chilled helps them stay fresher and tastier.
00:03:49There's another common myth about nuts.
00:03:52It's said that roasting them decreases calories, proteins, carbs, and fibers they contain.
00:03:57But no, both cooked and uncooked nuts have similar amounts of those.
00:04:02The main goal of roasting nuts is to enhance their flavor and crunchiness.
00:04:06Keep this in mind, though.
00:04:07When nuts are roasted, the healthy fats they contain may get damaged, and in the end, this can result in
00:04:14a reduced nutrient content.
00:04:16Now, let's talk about avocados.
00:04:19Don't toss them in the fridge if you want them to ripen on schedule.
00:04:22They like hanging out at room temperature.
00:04:25We can also put an end to another avocado-related myth.
00:04:29Avocados are fattening.
00:04:30Yeah, they do have a high-fat content, compared with most other fruits.
00:04:34But this doesn't necessarily make them bad for your health.
00:04:38In fact, avocados contain what's often called healthy fats, which can help reduce harmful cholesterol levels in your body.
00:04:45Now, let's carry on with diet and food.
00:04:48Swapping white table sugar for unrefined options like honey, maple syrup, and coconut sugar is supposed to make your diet
00:04:55healthier.
00:04:56Well, don't fall for this myth.
00:04:58Sugar is sugar, no matter whether it's refined or unrefined.
00:05:02While unrefined sugars may contain a few extra vitamins and minerals, the advantage is minimal because they're still considered added
00:05:10sugars.
00:05:11These added sugars can add up and contribute to your diet's recommended limit on daily sugar intake.
00:05:18Full-fat products aren't a one-way ticket to weight gain.
00:05:21That's a myth from the 80s and 90s.
00:05:24Some people are still scared of fat, but it shouldn't be the case.
00:05:27Fat plays a few essential roles, such as protecting our organs, maintaining cell membranes, supporting health and development, and helping
00:05:35absorb vital vitamins.
00:05:37The key is to choose heart-healthy, unsaturated fats like olive oil, canola oil, nuts, nut butter, and avocados over
00:05:46saturated and trans fats found in fatty meats and high-fat dairy products.
00:05:51There's a common belief that avoiding carbs entirely will make you lose weight.
00:05:56Well, that's a myth too.
00:05:58Low-carb diets have made their rounds, vilifying carbs, including fruits and whole grains.
00:06:03While some people have had success with these diets, it's usually because they've cut out highly processed, carb-laden foods,
00:06:10like chips, cookies, and white bread.
00:06:12You know, all the stuff we like.
00:06:14Eliminating an entire food group isn't the best approach, as you might miss out on essential nutrients.
00:06:20Another belief is that you can get rid of body toxins with a detox diet.
00:06:25Well, sorry, most detox diets don't live up to their promises.
00:06:29Your body is already good at detoxing itself with the help of your liver, kidneys, and gastrointestinal tract.
00:06:36You don't need to buy any special products.
00:06:38If you want to rejuvenate your body, focus on eating more whole foods, staying hydrated, and cutting out highly processed
00:06:46junk food.
00:06:48Okay, I have three life hacks for you.
00:06:51These aren't myths.
00:06:52Firstly, you can stop a pot from boiling over by putting a wooden spoon over its top.
00:06:58Secondly, if you position a cheese grater vertically, there's a better way to use it.
00:07:03Lay it down horizontally.
00:07:05This way, the process will be less taxing for your arms.
00:07:08My next tip is about your yoga mat.
00:07:10Leaving it in a hot, humid spot like your car can ruin it.
00:07:14Keep it cool and dry for maximum yoga zen.
00:07:19Now, many people know they should keep their fancy fragrance bottles away from direct sunlight.
00:07:24So, some people store them in the refrigerator.
00:07:27This isn't the right move, unless you want your perfume to lose its overall depth.
00:07:32I mean, yes, fragrances don't like heat or humidity, but the interior of a refrigerator is too dry and cold
00:07:39for them.
00:07:40So, it has the opposite effect and breaks down the scent molecules.
00:07:44And please, resist the urge to rub a bit of perfume on your wrist.
00:07:48It may be tempting, but rubbing your fragrances is a big no-no.
00:07:52This practice not only muddles and weakens the scent, it also causes the top notes to evaporate quickly.
00:08:01They say that if you have old photos in your house, the right way to stash them is by putting
00:08:07them in cardboard boxes.
00:08:08Well, this is a misconception.
00:08:10These types of boxes can damage your memories.
00:08:13Go for acid-free archival boxes if you want your pictures to look as good as new.
00:08:18The next one is more of a hack than a myth.
00:08:21It turns out dishwashers are more user-friendly than we give them credit for.
00:08:26When you're loading or unloading the dishwasher, you can save your poor back from unnecessary strain by pulling out the
00:08:33basket.
00:08:34You might think that foundations are safe at room temperature.
00:08:38But if you store your foundation in a makeup bag, heat can mess with the oils in your makeup.
00:08:43So, pop this product in a cool drawer.
00:08:46Eye creams and serums can benefit from the chill, too.
00:08:50Organic or homemade cosmetics without preservatives should also be refrigerated.
00:08:54But always check expiration dates.
00:08:57I know I do.
00:09:01You see these blades?
00:09:02They have notched corners to make your cutting experience smoother.
00:09:06Ooh.
00:09:07The front-edge notch helps with separating blades during manufacturing,
00:09:11while the trailing-edge notch helps the blade glide easily.
00:09:15And a fun fact.
00:09:16That notch on the front also helps you spot unused sections of the blade.
00:09:21Just a little visual indicator to make your life easier.
00:09:24When it comes to silver versus black blades, they're both made from the same stuff.
00:09:29But black blades are sharper and are better suited for cutting through tough materials,
00:09:34while silver blades strike a balance between cutting power and durability.
00:09:38If you want that extra cutting, oomph, go for black.
00:09:42Oh, almost forgot.
00:09:43The only thing those blades aren't meant to cut is food.
00:09:47It has a rust-proofing oil coating, which is not safe for humans.
00:09:52Check this one out.
00:09:54It's totally giving me childhood vibes.
00:09:56Now, I remember my grandma having tomato-shaped pin cushions just like this.
00:10:01And sometimes they would look more like a salad, with a little pepper thrown in there.
00:10:05Well, believe it or not, this salad actually has a purpose.
00:10:10The tomato keeps your pins in place, while the pepper keeps them sharp.
00:10:14Those peppers are filled with sand, which helps keep your pins nice and sharp.
00:10:19And it's not just sand.
00:10:21Crushed walnuts can also be used to keep your pins in tip-top shape.
00:10:26Now, look at this multiple pocket tool and this little hook on it.
00:10:30It's a bit of a mystery, but it's actually pretty handy.
00:10:33I counted at least four different applications.
00:10:37One, you can use it to carry all sorts of awkward stuff, like camping gear or heavy parcels.
00:10:42Two, need to twist some wire or play around with knots?
00:10:46The parcel hook has got you covered.
00:10:49Three, this hook can save the day with those stubborn zippers, like the ones on your luggage.
00:10:54Four, it's great for pretending to be a budget version of Captain Hook.
00:10:59If you know more applications, let me know in the comments.
00:11:03Apple users, with this feature, you'll never get laundry surprises again.
00:11:08Now, I bet you've had this situation at least once in your life.
00:11:12You wash your stuff, and when you take it out of the washing machine, the size seems to only fit
00:11:17your cat.
00:11:18Your iPhone camera can actually translate those funky laundry symbols for you.
00:11:23There are two requirements, though.
00:11:25So, you must have iOS 17, and your phone must be in English.
00:11:29Take a photo of the care label, go to the Photos app, and see the details of the image.
00:11:34Everything will be automatically decoded and explained to you.
00:11:39Now, many toasters come with nifty removable crumb trays at the bottom.
00:11:44It's super important to give these trays a good clean every now and then to keep your toaster running smoothly
00:11:49and avoid any potential fire hazards.
00:11:52Just pop them out, shake out the crumbs, and you're good to go.
00:11:56Where you shake them out is up to you.
00:11:59Those little compartments on your gas pump aren't just for show.
00:12:02They're actually there to hold your cap while you're filling up.
00:12:05This nifty feature keeps things tidy and prevents any spills or drips on the handle.
00:12:11So, say goodbye to messy refueling experiences and hello to a cleaner pump.
00:12:16Plus, it makes the whole process way more convenient and efficient.
00:12:21Now, I'll bet your oven gets so greasy and dirty sometimes that you can even hear it oink.
00:12:27Just kidding.
00:12:28I know you're a tidy person.
00:12:30Anyway, if you're looking for a way to bring your kitchen cleaning to a whole new level, here's a tip
00:12:36for you.
00:12:36Most oven doors have handy latches that let you pop the door off for easy cleaning, saving your pore back
00:12:44from the strain.
00:12:45When you're draining noodles or potatoes, there's no need to bother transferring everything to a colander in the sink.
00:12:52Just throw the colander right into the pot, hold it down, and pour the liquid out.
00:12:57It makes life so much easier, especially when you want to save that starchy water for recipes.
00:13:03It's a must for authentic pasta, by the way.
00:13:07So, let's say you've snagged this gem at a thrift store a while back for just under a dollar.
00:13:13It's seen better days, serving as an ashtray, but you decide it's time to give it a new lease on
00:13:19life.
00:13:20Here's the lowdown on how to make it shine again.
00:13:23Mix up a solution of boiling water, baking soda, and table salt in a bowl lined with aluminum foil.
00:13:30Let the piece soak for about 15 minutes, and repeat this process three times.
00:13:35In between soaks, gently scrub any rough spots with a microfiber cloth.
00:13:40After the final soak, dry the piece off and rub on some toothpaste, baking soda, and peroxide.
00:13:47Buff out any remaining tarnish with a clean, dry microfiber cloth.
00:13:51Rinse it off, and now your piece is practically gleaming like a mirror.
00:13:58These aluminum foil boxes have nifty little tabs on the sides that make it super easy to grab a sheet
00:14:04without any hassle.
00:14:05It's like a fancy little bonus that makes the product a breeze and ensures you'll have a smooth sailing experience
00:14:12every time.
00:14:14Manual can openers often come with a handy built-in feature, also known as a bottle opener.
00:14:20It's like getting two tools in one.
00:14:22But did you know that this bottle opener actually has another useful function?
00:14:27It can help you loosen those stubborn, hard-to-open jars.
00:14:31Simply lift the lid slightly at a couple of points with the bottle opener,
00:14:35and then watch it as it effortlessly twists right off.
00:14:39Yeah!
00:14:42Okay, I just found that, apparently, you're supposed to save the first and last slices of a loaf of sliced
00:14:48bread for last.
00:14:49It's like a bread hack or something.
00:14:51Apparently, those end pieces help keep the rest of the bread fresher for longer,
00:14:55and you shouldn't eat them until you've devoured the rest of the loaf.
00:14:59So, next time you're making a sandwich, save those heel slices for the very end.
00:15:04Even bread-eating needs a good strategy.
00:15:07Now, look at those blue levers on the top rack of your dishwasher.
00:15:11I was curious about them, too.
00:15:12And it turns out they're actually water bottle sprayers.
00:15:16They help to ensure that your bottles get a thorough cleaning and rinse during the wash cycle.
00:15:23Many vegetable peelers have those little scoops on top for taking out the eyes from potatoes.
00:15:28And here's a cool tip.
00:15:30You can actually use vegetable peelers in both directions to peel faster.
00:15:34But most people just stick to one direction.
00:15:39When using yellow mustard, make sure to push the lid of the bottle all the way open until you hear
00:15:44a satisfying click.
00:15:46This way, the lid will stay securely in place and won't get in the way when you're dispensing the mustard
00:15:51onto your food.
00:15:52It's a simple step that can make your condiment experience hassle-free and enjoyable.
00:15:57So there!
00:16:00You know that little hole at the end of your pot or pan?
00:16:03Well, it's not just for show.
00:16:05You can actually use it as a handy holder for your forks and spoons.
00:16:09Next time you're cooking up a storm in the kitchen, just pop your utensils in that convenient little hole and
00:16:15keep them close at hand.
00:16:18Okay, just a heads-up to remember to switch the direction of your ceiling fan for the changing weather and
00:16:25to give it a good clean, too.
00:16:26I've seen that a lot of folks found it helpful before to reverse the fan's direction by flipping a switch
00:16:32for different seasons.
00:16:34So this is just a friendly reminder to go ahead and do it again, pushing hot air down and pulling
00:16:40cold air up.
00:16:43When you're chowing down for some pizza, just tear off the top of the box and use it as a
00:16:48big old plate.
00:16:49You can even rip the box in half and fold it to save some leftovers for later.
00:16:55Well, that's it for today.
00:16:56What, you want to know more cool facts?
00:16:58Sure, but you'll have to subscribe and hit the bell to get more videos.
00:17:03I'm waiting.
00:17:04Go ahead.
00:17:08You know how they say, when in Rome, do as the Romans do?
00:17:12Meaning, in Rome, you need to make sure your goldfish has a deluxe bowl to live in.
00:17:17In Nigeria, don't you dare to bring your own wheelbarrow.
00:17:21And perish the thought of adding as much mayo as you want to your dish when you're in France.
00:17:27Yep, bands around the world may be surprising, to say the least.
00:17:31Number 1.
00:17:32You will never see a good old doorknob in Vancouver, Canada.
00:17:36Some time ago, the city changed its building code to require the use of cool and sleek door levers instead.
00:17:42This change is all about making buildings more accessible and easier to use.
00:17:47Not only new buildings are getting a new makeover.
00:17:50Even Vancouver's historic city hall had its fancy Art Deco doorknobs replaced with shiny gold levers.
00:17:57But it's not that you can't legally have it in your house.
00:18:00There isn't a team of doorknob police coming to your house to confiscate your knobs.
00:18:04You can keep them as long as you like.
00:18:08Number 2 comes with a geoguesser tip for y'all.
00:18:11If you see this chair in the picture, it means it's 100% not in Basel, Switzerland.
00:18:17It's called a monoblock chair, and it's special.
00:18:20You see, most objects give away clues about when and where they're from,
00:18:24like the shape of electrical outlets or the labels on your shampoo bottle.
00:18:28But the monoblock is context-free.
00:18:31Some people call them one of the world's most perfectly designed objects,
00:18:35while others say the homogenous nature of the chair is disturbing and the real evil of globalization.
00:18:41But why is it banned in Basel?
00:18:43Turns out the authorities just want the city to be pretty, and the chair design isn't to their liking.
00:18:49Right.
00:18:49If you want to keep one in your backyard, feel free.
00:18:52But they've been a big no in public spaces since 2008.
00:18:593.
00:18:59If you were ever thinking of bringing a wheelbarrow to Nigeria, I've got some news for you.
00:19:05Don't even try.
00:19:06Should you need it for some reason during your stay in Nigeria, just buy one there when you arrive.
00:19:11The authorities won't let you bring your imported wheelbarrow across the border.
00:19:15Why?
00:19:16Well, they're all about supporting their own manufacturing industry.
00:19:20So they want to give their local wheelbarrow makers a chance to shine.
00:19:25At number 4, we've got China, where the authorities decided to put a stop to time travel.
00:19:31Wait a minute.
00:19:32It's not what you think.
00:19:33No time travel machine has been invented.
00:19:36The ban is on TV shows and movies.
00:19:38By the way, it's not something new.
00:19:40The law was introduced in the early 2010s.
00:19:43Apparently, the big shots in charge want to keep things real and are not too keen on distorting historical events.
00:19:50They say some scripts are getting a bit too wild, making up myths, promoting superstition, and disrespecting the country's past.
00:19:595.
00:20:00Coffee pods.
00:20:01They've become super popular because they make brewing coffee so easy.
00:20:05But Hamburg, Germany doesn't seem to be a fan of those pods.
00:20:08Around 8 years ago, they took a stand by banning plastic coffee pods from authorities' offices.
00:20:14These little pods are made of various materials, making recycling a real challenge.
00:20:19While it's true that these coffee capsules can create a lot of problems, they're still loved by many.
00:20:25In fact, they've become a big hit in the US and Europe, making up a chunk of the coffee market.
00:20:31Hamburg is hoping to lead the way in showing people just how wasteful these pods really are.
00:20:37Number 6.
00:20:38Chewing gum.
00:20:39It has been banned in Singapore since 1992.
00:20:43The ban was put in place to stop people from sticking gum in all sorts of weird places, like subway
00:20:48doors, lock cylinders, and elevator buttons.
00:20:51Yuck!
00:20:52But costly train shenanigans were the last straw for the authorities.
00:20:56The ban was put in place after some serious gum incidents on the Mass Rapid Transit, or MRT, trains in
00:21:03the late 80s.
00:21:04Some mischievous or mischievous pranksters have been gumming up the words on MRT trains by sticking chewing gum on the
00:21:11door sensors.
00:21:12That caused a sticky situation and messed up train services.
00:21:16And there you have it.
00:21:17Chewing gum got completely banned.
00:21:19Now, just a note here.
00:21:21Yep, these are gums prescribed for therapeutic or dental reasons.
00:21:24And yep, they're still allowed.
00:21:26Also, don't get this whole ban wrong.
00:21:28It's not illegal to chew gum in Singapore.
00:21:31So if you come there as a tourist, you can bring in a little gum for personal use if you're
00:21:36traveling.
00:21:36Just do not stick it under this nice park bench, okay?
00:21:40What will create you a ton of troubles, though, is importing and selling chewing gum.
00:21:47Iceland is number 7 in our ban hit parade.
00:21:51Back in 1994, Reykjavik was like, no dogs allowed.
00:21:55It wasn't because they were all about cats.
00:21:57It was to stop this nasty tapeworm from spreading.
00:22:00The disease was serious business, causing all sorts of health problems.
00:22:04But don't worry.
00:22:06Dogs are cool now as long as they follow the rules.
00:22:09Nowadays, in Reykjavik, it's all about the cats.
00:22:11They're everywhere, roaming the streets like they, you know, own the place.
00:22:15You can't walk two steps without seeing a furry little friend begging for attention.
00:22:20These Reykjavik kitties are so popular that they even have their own Facebook page.
00:22:25People love them.
00:22:26And some even carry around treats just in case they come across a friendly feline.
00:22:31And since there aren't many threats to cats in Iceland, they're thriving.
00:22:368.
00:22:37The Philippines
00:22:38Now, this one is really weird.
00:22:40Singing my way in karaoke bars is sort of banned in this country.
00:22:44This seemingly harmless song has been linked to some pretty serious consequences,
00:22:49like fistfights and even people's early demise.
00:22:52No one knows the exact number of lethal cases caused by this song,
00:22:56but there have been at least a handful of incidents in the last 10 years.
00:23:00The song's lyrics, which can come off as a bit arrogant and prideful,
00:23:04seem to rile people up when sung in a not-so-great way.
00:23:08This has led some karaoke bars to unofficially ban the song to prevent any craziness from breaking out.
00:23:169.
00:23:17Hey, have you heard about Japan's Metabo Law?
00:23:20It's all about measuring waist sizes to tackle obesity.
00:23:23It was introduced in 2008, and the idea was that if companies and local authorities didn't meet the goals,
00:23:30they would face financial penalties.
00:23:32The Ministry of Health believed this campaign would help prevent various health conditions.
00:23:37So, every year, people aged 40 to 75 had to get their waist measured.
00:23:43Employers and local authorities needed to make sure at least 65% of people participated.
00:23:48The goal was to reduce Japan's obesity rates by 25% by 2015.
00:23:54And if they hadn't made it, they would have gotten slapped with a fine.
00:23:57Did it work?
00:23:58Well, in 2024, there were only 4.5% of people who reportedly have weight issues in Japan.
00:24:07Number 10.
00:24:08And we're back to Canada.
00:24:09So, if you catch someone in there counting out pennies in line, you can totally have some fun with them.
00:24:14Legally speaking, of course.
00:24:16According to the Canadian Currency Act, there's a limit to the number of pennies you can use in a transaction.
00:24:2225, to be exact.
00:24:24So, if someone tries using 26 coins, you can play sheriff and send them to coin jail.
00:24:30Snatch up their pennies as evidence.
00:24:31Yeah.
00:24:3311.
00:24:34And a condiment-regulated country here.
00:24:37Apparently, in France, they're cracking down on condiments in public schools.
00:24:41They're trying to make meals healthier for students.
00:24:44The rule is that you can't just go crazy with mayo, ketchup, and vinaigrette anymore.
00:24:49They have to be served according to the dish.
00:24:53Finally, Italy.
00:24:54In Rome, you can't keep your goldfish in a boring old glass bowl.
00:24:58Nope, that's considered cruel, because those little guys need their oxygen flow.
00:25:03Plus, if you keep them in a bowl for too long, they might go blind.
00:25:07Also, you can't give away goldfish's prizes.
00:25:10The law has a whole subsection about it.
00:25:13So, if you're planning on bringing a goldfish home from your next trip to Rome,
00:25:16make sure you've got a fancy tank ready for them.
00:25:20And thank you for watching!
00:25:24Have a good look at the front of your sweatshirt.
00:25:27Okay, let's ignore the pizza stains for now.
00:25:29Ever notice that V-shape right at the bottom of the collar?
00:25:32That small V-patch isn't just a decoration.
00:25:35It serves more than one purpose.
00:25:37Made from a double layer of webbing material, just like waistbands and cuffs,
00:25:41these inserts allowed the wearer to put on the sweater without losing any shape over time.
00:25:45As the sweatshirt would be pulled down over the head,
00:25:49the V-insert would stretch and flex to allow a lot of wiggle room.
00:25:52The other benefit the V-pattern gives is to absorb all that sweat.
00:25:56The chest is a major area of perspiring.
00:25:59Just look at soaked shirts after doing something physical.
00:26:02Although, the V-insert can only take so much.
00:26:06That extra pocket on the right side of a suit jacket is called the ticket pocket.
00:26:10They used to store coins for people on horseback to pay tollbooths without opening their jackets.
00:26:16When train travel became more popular, they were perfect for tickets and passes.
00:26:20As for the left chest pocket, it's used to store handkerchiefs,
00:26:24keeping them away from the other cluttered and dirty pockets.
00:26:27Metallic zippers have a hidden lock built in.
00:26:30Next time you've put on a pair of pants, shorts, or skirt,
00:26:33never leave the zipper handle in an upward position.
00:26:36Push the little zipper tab downwards, and it'll automatically lock.
00:26:40To mute your annoying beeping microwave, look closely at the front panel for a sound button.
00:26:45It may have been there all along, just begging to be pressed.
00:26:49If there's no button, try pressing and holding 1, 0, stop, or cancel.
00:26:54It will either result in turning off the beeping sounds or activating a lock feature.
00:26:58Of course, if your microwave doesn't have any mute function at all,
00:27:02you'll just have to keep running to stop the timer late at night.
00:27:05Nintendo Switch cartridges have a hidden safety function,
00:27:08and it's going to leave a bad taste in your mouth.
00:27:11Although non-toxic, denotonium benzoate coats the cartridge in a sour, peppery, and bitter substance
00:27:17to prevent kiddos from swallowing them.
00:27:20This chemical compound is one of the most bitter flavors known to humanity,
00:27:24commonly used to keep people from consuming things they're not meant to.
00:27:27There's not much privacy while using a public toilet,
00:27:30especially when the door doesn't reach the floor at all.
00:27:33But these gaps are there for emergency access,
00:27:36in case the person inside needs immediate help.
00:27:39The gap also works for ventilation, thank goodness,
00:27:42and to stop people from lingering around the toilet too long.
00:27:46Toothpicks have a built-in holder to prevent you from just leaving them on the table.
00:27:50Just break off the top, it's that simple.
00:27:52Place that on your table and your toothpick between the notches.
00:27:55Pointy end up, of course.
00:27:57Now, it won't touch the table and get all dirty.
00:27:59You can do the same with disposable chopsticks.
00:28:02Break off the top piece before you pull them apart.
00:28:05Those tiny dimples on golf balls actually give a greater lift to the ball
00:28:09and reduce air resistance, meaning the ball can go further with them.
00:28:13These dimples come in spherical and hexagonal shapes,
00:28:16with each slightest change affecting the ball's performance.
00:28:20So, choose them carefully.
00:28:22Plastic wrap boxes have hidden little holders that stop the roll from jumping out of the box.
00:28:27They're little cardboard tabs on the sides that lock into the tube inside
00:28:31while making it easy to glide the film out.
00:28:34Just push them in and never be frustrated again.
00:28:37Gosh, I wish that would work with other stuff.
00:28:40The seven spikes on top of the Statue of Liberty's crown
00:28:43don't represent the seven seas and the seven continents at all.
00:28:47They're representing the sun's rays, giving a halo to show that she is divine.
00:28:52In the United States, 12 different Federal Reserve Banks print all the money.
00:28:57So, if you want to know where your money comes from, just look for these small codes.
00:29:01A-1, Boston
00:29:02B-2, New York
00:29:04C-3, Philadelphia
00:29:05D-4, Cleveland
00:29:07E-5, Richmond
00:29:08F-6, Atlanta
00:29:10G-7, Chicago
00:29:11H-8, St. Louis
00:29:13I-9, Minneapolis
00:29:15J-10, Kansas City
00:29:17K-11, Big D, Little A, Double L-A-S
00:29:20It's a song
00:29:21L-12, San Francisco
00:29:23Never call it Frisco.
00:29:25Meanwhile, the bristles on the side of every escalator
00:29:29are in place to encourage people to stay away from the edge, meaning they're less likely
00:29:33to face a mishap with a trapped bag or shoelace.
00:29:36Did you hear about the octopus caught on the escalator?
00:29:39It was a stretch.
00:29:40Old-fashioned pin cushions that are large tomato with a strawberry attached are more
00:29:45than a place for your needles.
00:29:46The strawberry contains an emery board.
00:29:49When you stick your pins and needles into the strawberry, the emery board keeps them rust-free
00:29:53and sharpens them as well.
00:29:56Some people still forget to engage the hose from their car after filling up with gas.
00:30:00Luckily, a lot of gas companies realize this, so if you happen to drive off with a hose
00:30:05still attached to your car, there's a magnetic connector that disengages when pulled.
00:30:10Those different colored bread tags use a color-coded system to show the day that they were baked.
00:30:15They are usually blue tags for Mondays, green tags for Tuesdays, red tags Thursdays, white
00:30:21tags Fridays, and yellow tags for Saturdays.
00:30:24On the back of most beauty products, you'll find a small symbol on the back that indicates
00:30:29how long it'll stay good for.
00:30:31For example, 2M means two months after opening.
00:30:35Some jackets have those extra flaps with a button on the shoulder, and they actually have
00:30:40a use.
00:30:40These are perfectly designed for holding your purse, backpack, or bag in place and secure.
00:30:46Pom-poms on the top of beanies were never just a fashion statement.
00:30:49They were for protection, placed on top of the headwear to protect sailors from accidentally
00:30:55hitting their heads while moving around on a ship.
00:30:58Pom-poms touch the roof, so don't go any higher.
00:31:01They don't appear on every type of measuring tape, but diamonds or black circles are there
00:31:06to help contractors measure the proper placement of studs in a wall.
00:31:10Those little holes on your baseball cap aren't some fashion trends that stuck around for years
00:31:15and have never been changed.
00:31:17These holes are actually called eyelets, and they're to keep your head well-ventilated,
00:31:22not for appearance.
00:31:23If you have YKK printed on your zipper, they're not some secret code to be cracked.
00:31:28Those three letters appear on so many zippers globally because they're the symbol of the
00:31:33world's most universal zipper manufacturer, the YKK Group.
00:31:38Every can of soda comes with a tab for easy opening of the tasty beverage, and every single
00:31:43one of them has a relatively large hole in the top.
00:31:46While it can make it easier to get your finger under the tab to get your soda, its intended
00:31:51purpose is a straw holder.
00:31:53Spin the tab over the opening and place your straw through it to secure it in.
00:31:57Disposable lids do a great job of keeping your drink inside the cup, but that's not its
00:32:02only purpose.
00:32:03When you're ready to sip on your drink, the lid has specially designed ridges to double it
00:32:08as a coaster and hold onto the bottom of your beverage tightly.
00:32:11The tiny black dot between the lens and the flash on the back of your iPhone is actually
00:32:16for a great purpose.
00:32:17It's the third microphone to provide superior sound quality by eliminating background noises
00:32:23and to pick up your voice much clearer in a crowded environment.
00:32:27Gas cans that have two holes with caps aren't there to fill different-sized equipment.
00:32:32The second hole is meant to be uncapped before you pour your gas to prevent that glugging effect.
00:32:38By allowing more airflow through, the smoother the gas will pour out.
00:32:42That little arrow next to the gas symbol on your car's dashboard shows you which side
00:32:47your gas tank is on.
00:32:49It'll help you when you go fill up your gas tank, especially if you're borrowing a different
00:32:53car than your own.
00:32:55Look at a check and see MP near the signature line.
00:32:58That means the check printer used microprint as one of the check security features.
00:33:03The lines look like a regular line to the untrained eye, but they're words like the bank's name,
00:33:09authorized signature, United States government, or even original document.
00:33:13That little disc that's underneath bottles isn't just a leftover part of the production process.
00:33:19It creates an even tighter seal with the lid.
00:33:22So, even if the bottle was turned upside down, the liquid doesn't leak out everywhere.
00:33:27The plastic disc keeps carbonated sodas carbonated for longer with this seal.
00:33:31The indent in the bottom of wine bottles is called a punt.
00:33:35But it's not just something to help you hold onto the bottle.
00:33:38The punt makes the wine bottle stronger.
00:33:40So if dropped, the cork won't fly across the room with all that pressure.
00:33:45Now here's a trick.
00:33:46Instead of putting the box grater vertically on top of a plate, put it horizontally,
00:33:51with no plate underneath, of course.
00:33:53This way, you won't risk scraping your knuckles, because only your fingertips will
00:33:57eventually touch the grater when you reach the end of the process.
00:34:00Also, it gives the grater more stability, when otherwise, you'd have to balance the grater
00:34:05or even hold it in the air with the other hand.
00:34:07When you're done, or when there's just too much grated stuff on the bottom wall of the grater,
00:34:12simply turn it on its side to pour the contents into the bowl or plate.
00:34:17Flowers in a vase would stay fresher for longer if not for the bacteria that breed in the water.
00:34:22Since copper has some antibacterial properties, dropping a penny into the water will help keep
00:34:28the microbes at bay and let you enjoy your flowers for that little bit longer.
00:34:32An easy way to check if your bed linen has dried completely
00:34:36is to put a small mirror in between the layers for about 5 minutes.
00:34:40If the mirror has steamed up when you pick it up, it means the sheets are still a bit damp.
00:34:45Let them dry until the mirror stops getting cloudy.
00:34:48A damp bed is a lovely breeding ground for fungi and bacteria.
00:34:53Okay, I'm in.
00:34:54If you have a not-very-healthy habit of eating in front of your computer,
00:34:59you'll be surprised at how much crumbs and grime there is inside your keyboard.
00:35:04Now, you can just turn it over and shake it vigorously, of course,
00:35:08but that's not very good for any piece of tech, you know.
00:35:11So instead, take a post-it note and run its sticky part over the keyboard.
00:35:16It will collect the little pieces of trash like magic.
00:35:20Even a better way to do it, though, is to take a slime and stick it to the keyboard,
00:35:24then take it away, squeeze it, and stick again in another part.
00:35:28The slime will fill the entire space between the keys,
00:35:31and its sticky properties will let it gather every little bit of garbage.
00:35:36Separating egg yolks from whites is easier using a plastic bottle.
00:35:40Break the necessary number of eggs into a bowl,
00:35:43and then take an empty plastic bottle and squeeze it.
00:35:46Hold the bottle over the yolk and release.
00:35:49It'll pull in air and the yolk together, leaving the white in the bowl.
00:35:53Repeat with the rest of the yolks and you're done!
00:35:56And that's no yolk!
00:35:58If you're tired of spitting out the stones when eating cherries
00:36:01or want to make a cherry pie, push the stones out with a straw.
00:36:06Also, many garlic presses have a special tool on their handle
00:36:09that can be used exactly for that.
00:36:12Cleaning a blender can be a nuisance if you do it manually.
00:36:15Instead, fill it with hot water and add some liquid soap or detergent,
00:36:19then run it for about 10 seconds.
00:36:21Rinse it afterwards, and it's clean.
00:36:24Plaster walls can crumble, flake, and spread dust all over the floor
00:36:28when you hammer nails into it.
00:36:30Cut a strip of masking tape and stick it to the place you want to hammer a nail in.
00:36:35The tape won't let the plaster crack and crumble,
00:36:38leaving the hole neat and clean.
00:36:39Small scratches and dents on wooden furniture can be removed with some toothpaste or a walnut.
00:36:46For toothpaste, rub a pea-sized amount of it into the scratch until it's gone,
00:36:51then wipe the leftovers with a damp cloth.
00:36:53For a walnut, take a half of that brain-shaped nut and rub it into the dent.
00:36:59Then rub the area with your fingers and buff it with a soft cloth.
00:37:03This'll help the wood absorb the oil from the nut, making the scratch sealed and gone.
00:37:08The sticky residue on jars left after you remove the stickers won't be easily removed by water and detergent.
00:37:15So, take some vegetable oil instead.
00:37:17Soak a cotton pad in it and wipe the sticky surface.
00:37:21Let it sit for a while and then wash the oil away together with the residue.
00:37:26If you can't comfortably reach the wick of a candle with a lighter,
00:37:30hey, take a stick of spaghetti.
00:37:32Light up its end and you'll get a burning stick that's easy to use for hard-to-reach places.
00:37:37Now, next time your razor blade's getting dull,
00:37:40try rubbing it backwards on a pair of jeans for regular upkeep.
00:37:44Not while you're wearing them, of course.
00:37:46Make sure you keep the blades dry, too, or even kept in mineral oil.
00:37:50That'll stop them from rusting.
00:37:52Keep all those jelly, ketchup, peanut butter, and mayo fresher for longer in your fridge
00:37:57by turning the contents upside down.
00:38:00This creates a partial vacuum inside the container, helping prevent mold growth.
00:38:05Storing ice cream upside down will prevent freezer burn, too.
00:38:09To bring your permanent marker back to life,
00:38:12simply put a few drops of rubbing alcohol into the felt material inside and shake.
00:38:17Once the felt absorbs the rubbing alcohol for a couple of minutes,
00:38:21the marker will be almost as good as new.
00:38:24Now, don't keep throwing away lettuce that goes black too quickly.
00:38:28Covering it with a dry paper towel and then placing it in an airtight container
00:38:32will help it keep fresher for much longer.
00:38:35This goes for any leafy greens you've got leftovers of.
00:38:38That sharpish bit sticking out of the cap of your favorite cream is there for a reason.
00:38:44These tubes are usually sealed with foil,
00:38:46so unless you love breaking your nails trying to open them,
00:38:49just flip the cap over and push.
00:38:52Your bobby pins might not stay in place if the grooves aren't facing the right way.
00:38:57They should always be on the bottom, close to your head.
00:39:00Still coming loose?
00:39:01Well, put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
00:39:06Now, your cotton rounds pack has those strings on it,
00:39:10so you can hang it on a handy hook in the bathroom.
00:39:12But there's no need to loosen and tighten it back up every time.
00:39:17Check out the bottom of the pack.
00:39:18It has a perforated line.
00:39:20Tear it open carefully, and you're good to go.
00:39:23Two zips too much?
00:39:25Maybe.
00:39:26But they come in handy as a clever anti-theft device.
00:39:29Just lock them together.
00:39:30Now, no one can open your backpack.
00:39:33Don't have a lock on you?
00:39:35You can also tie them together with some string,
00:39:37or even just a paper clip.
00:39:39Anything to slow those pickpockets down.
00:39:42That tiny little button on the back of a shirt collar is used to hold your tie in place.
00:39:47Hey, you don't want your tie trying to escape back there.
00:39:51Shoe manufacturers care about their customers,
00:39:53so most running shoes now have a special anti-blister system pre-installed.
00:39:59Sounds intense, but it's basically just that extra hole on top of your sneakers.
00:40:04Make a loop with the extra hole, inserting the lace backward.
00:40:07Cross your laces and put them through the loops.
00:40:10Now, pull the laces down to lock your foot in place.
00:40:13Now, run.
00:40:14Yeah, go ahead.
00:40:16Car headrests are all about comfort,
00:40:18and detachable headrests are all about safety.
00:40:21If you pull the headrest out, you'll see two sturdy metal bars.
00:40:25If you ever get locked or trapped in your car,
00:40:28you can use the bars to smash the window and get out.
00:40:32If you've got some pesky parsley stuck in your teeth, try this tip.
00:40:36It can be hard to get it out with loose floss.
00:40:39You need more tension, so just tie it in a knot.
00:40:43It's not an accident that soy sauce bottles have two spouts.
00:40:46The sauce is liquid, and it flows out of the bottle pretty easily
00:40:50once you turn it over.
00:40:51Most Asian food lovers have spilled it at least once in a lifetime.
00:40:55That's why nowadays, restaurants prefer serving soy sauce
00:40:59in special bottles that have two spouts.
00:41:01This design allows you to control when and how much sauce will come out.
00:41:06Just put your finger on one spout when you pour the sauce through another.
00:41:09If you press your finger tightly to the spout,
00:41:12the sauce will stop flowing,
00:41:14and if you remove your finger, it'll flow again.
00:41:17And don't forget to ask your server,
00:41:19Hey, wasabi!
00:41:21Alright.
00:41:22A hair straightener is an excellent tool,
00:41:24not only for treating your natural curls,
00:41:27but also for fixing crumpled money or documents.
00:41:30You can also use a regular iron for this purpose.
00:41:32Just make sure you don't turn on steaming mode,
00:41:35otherwise there's a risk of damaging the paper.
00:41:39Hairbands are good not only for getting your hair done,
00:41:41but also to open a glass jar with canned food.
00:41:44Your hands might slip on the tightly closed lid,
00:41:47and if you don't open the can from the first attempt,
00:41:50your palms tend to get sweaty,
00:41:52making the task virtually impossible.
00:41:55So, put a hairband on the lid to fix your hand
00:41:58and make your grasp stronger.
00:42:00A simple rubber band will do as well.
00:42:02Now, it's time to take my sweaty palms and go.
00:42:06Now, don't blame that little lump on your computer cable
00:42:09for getting stuck somewhere for the umpteenth time.
00:42:12The cylinder, shapes and colors may vary,
00:42:16actually prevents interference from other signals,
00:42:19like those your phone emits.
00:42:21A lack of privacy in public bathrooms,
00:42:24I mean those large gaps beneath where normal doors tend to be,
00:42:28is there for a reason.
00:42:30This way, people do their business faster,
00:42:32and there are fewer lines.
00:42:34Also, if something goes wrong,
00:42:36it's easy to find a person who needs help.
00:42:39In London, there are some poles that kind of look like street lamps,
00:42:43but there are no bulbs.
00:42:45Well, their official name is stink pipes,
00:42:48and they're a thing of the past now,
00:42:50but they used to come in handy back in the nineteenth century.
00:42:53These hollow poles would vent away the air
00:42:56and explosive gases with bad smells
00:42:58to prevent, shall we say, unwanted consequences.
00:43:03Blank pages in the books aren't actually for the author's signature.
00:43:07It's all about the manufacturing process.
00:43:10Books are printed on large sheets,
00:43:12so one sheet can fit in four pages.
00:43:15If a book has an odd quantity of printed pages,
00:43:18chances are you'll get a blank one for notes.
00:43:21Now, originally, golf balls were smooth.
00:43:25But some time ago,
00:43:26players noticed that overused balls with damages
00:43:29flew better than brand-new ones.
00:43:31At some point,
00:43:32they started producing balls with dimples.
00:43:36Windchill black dots help disperse the sun
00:43:39glaring right into your eyes.
00:43:41This sort of frame keeps the UV rays away,
00:43:43so it serves as sunglasses for your car.
00:43:47The tab on the rearview mirror has obvious functions.
00:43:51It holds your air freshener, that cute toy.
00:43:53But in reality,
00:43:55it was meant to be a tumbler between day and night mode.
00:43:58It reduces the glare from the car behind you,
00:44:01so you can't be blinded.
00:44:04Colored dots on chip bags
00:44:05aren't as useful as those on the windshield,
00:44:08but they have a purpose too.
00:44:10Manufacturers need them to control the package color
00:44:13and show what ink color was used on the package.
00:44:16No big deal.
00:44:17Your microwave has a silent mode.
00:44:20Seriously.
00:44:21If those beeps drive you nuts,
00:44:23press 1 or 0 and hold.
00:44:25It might work.
00:44:26Also, there is sometimes a silent button
00:44:30you kept ignoring all this time.
00:44:32Anyway, there are no two identical microwaves,
00:44:35so a manual should come in handy.
00:44:38Grocery cart loops have more functions than you think.
00:44:42You don't want to put your fancy white jacket
00:44:44in a cart next to carrots and Coke.
00:44:46This little hook-like thingy
00:44:48helps organize all the stuff in your cart better,
00:44:51so you can enjoy your shopping trip.
00:44:54Another thingy we often neglect
00:44:57is a point on an ointment cap.
00:44:59Most tubes are usually sealed with plastic film or foil,
00:45:03and opening it with your fingernails
00:45:05isn't the best idea.
00:45:07A point easily opens
00:45:08even the most safely sealed tube.
00:45:12Automatic lip liners and eye pencils
00:45:14have a sharpener installed in the package.
00:45:17The lid on the back part of the pencil
00:45:19doesn't only reveal the color.
00:45:21You can pull it out
00:45:22and sharpen up the product.
00:45:25Toothpicks come in different varieties,
00:45:27and one of them is a bit puzzling.
00:45:29Sometimes they have several grooves.
00:45:32The first one is weak,
00:45:33so it's easy to break the toothpick in two.
00:45:36The smaller section with one more groove
00:45:38can be used as a stand
00:45:40to avoid the contact with the table.
00:45:43You can make a makeshift stand
00:45:45for disposable chopsticks.
00:45:46They have a sort of lump at one side
00:45:49before you split the pair.
00:45:51So, next time you have a sushi dinner,
00:45:53try breaking off that lump
00:45:55instead of regular splitting.
00:45:57When you want to take a sushi break,
00:45:59just place the stick on this stand.
00:46:02Yeah, you've heard before
00:46:04that a drawer beneath your oven
00:46:06is there for keeping the food warm
00:46:07if the guests are running late.
00:46:09Here's one more hidden function.
00:46:11You can slow cook on lower temperatures
00:46:13in that drawer, too.
00:46:16All the bottles used to be
00:46:17of the same green color once.
00:46:20But later it was discovered
00:46:21that brown ones are way better
00:46:23at blocking UV light.
00:46:25Say no more.
00:46:27Stickers on fruit seem to provide
00:46:29zero information about the product.
00:46:31But if you look closer,
00:46:33you'll find some numbers
00:46:34that can tell you more.
00:46:36A five-digit number
00:46:38where the first number is nine
00:46:39is a good sign.
00:46:40You're about to buy
00:46:42an organic product.
00:46:44A four-digit number
00:46:45starting with a three or four
00:46:46means it was conventionally farmed.
00:46:49And if the number starts with an eight
00:46:51and there are five digits,
00:46:53well, it's best to leave it on the shelf.
00:46:56A dollar has its secrets, too.
00:46:59A large letter with a rim
00:47:01shows which bank is responsible
00:47:03for issuing this bill.
00:47:04There are 12 banks distributing currency.
00:47:07For example, the L says it was printed
00:47:10in San Francisco.
00:47:12Now, some cups look like they're chipped
00:47:15on the bottom,
00:47:16but they're produced this way.
00:47:17In fact, these dimples are supposed
00:47:19to keep the cup in place on wet surfaces,
00:47:21and it doesn't let excess water accumulate
00:47:24while it's in a dishwasher.
00:47:26Small hollows in a chocolate box
00:47:28are designed for chocolate lovers.
00:47:30Press the closest deepening
00:47:32to the chocolate that you want to grab,
00:47:34and it'll jump out of the box
00:47:36right into your hand.
00:47:38Bath foam can be more
00:47:39than just a pleasant smell.
00:47:41It also has a sort of
00:47:44thermoregulatory function.
00:47:45The bubbles save water heat,
00:47:47so you can enjoy your bath
00:47:49a little longer.
00:47:50Disclaimer,
00:47:51it works for acrylic bathtubs only.
00:47:53Those made of metal
00:47:55lose heat fast,
00:47:56no matter how much foam you made.
00:47:59A good doorknob
00:48:01is one that's made of brass,
00:48:02bronze,
00:48:03or some copper alloys.
00:48:05These metals have an anti-germ effect.
00:48:07Bacteria spread way slower on them.
00:48:10They also get rid of germs
00:48:12pretty fast,
00:48:13within a couple of hours.
00:48:14No, it doesn't mean
00:48:16you don't have to wash your hands.
00:48:19If you pour milk or juice
00:48:20right onto your t-shirt
00:48:22every single time,
00:48:23you're probably not doing it right.
00:48:25Try pouring it
00:48:26from the other side of the carton.
00:48:28It sloshes less
00:48:29and is easier to control.
00:48:32There's only one way
00:48:34you can store
00:48:34your peanut butter right.
00:48:36If you place it
00:48:37the regular way,
00:48:38it may get a bit solid
00:48:39before long.
00:48:40The trick is to store it
00:48:42upside down,
00:48:43so the oils don't stay
00:48:44on the bottom all the time
00:48:46and distribute evenly.
00:48:48A dinner jacket
00:48:50has small pockets
00:48:51above regular ones,
00:48:52and they're not useless.
00:48:53They're called ticket pockets
00:48:56and were designed
00:48:57so that gentlemen
00:48:58wearing such jackets
00:48:59could easily access
00:49:00the tickets
00:49:01and show them on a train.
00:49:03They could also store cash
00:49:05and other small loose items
00:49:06in a super convenient way.
00:49:08Now, whatever coffee shop
00:49:10you go to,
00:49:11all the disposable cups
00:49:13look exactly the same,
00:49:14only the logo changes.
00:49:16The secret here
00:49:18is the special shape
00:49:19that allows you
00:49:20to enjoy your drink easily.
00:49:22The top is always wider,
00:49:24which allows it
00:49:25to accommodate your nose
00:49:26while you're drinking,
00:49:27and the bottom
00:49:28is always narrower,
00:49:29so that anyone
00:49:30can hold it easier,
00:49:31even if the hand
00:49:32is quite small.
00:49:34This width difference
00:49:35also allows
00:49:36the cups to stack.
00:49:39Triangular flaps
00:49:40on small juice cartons
00:49:41can help control
00:49:42unwanted spillage.
00:49:44If you flip them
00:49:45and use them
00:49:45as handles for the carton,
00:49:47you won't press the package
00:49:48so the juice
00:49:49won't be squeezed
00:49:51uncontrollably.
00:49:52Now, if you have
00:49:53a mason jar
00:49:54and a blender
00:49:55with a screw on top,
00:49:56this secret
00:49:57is life-changing.
00:49:58You can actually
00:50:00put a mason jar
00:50:01directly onto the blender
00:50:02and make any shake
00:50:04you want
00:50:04without having
00:50:05to wash the blender jar.
00:50:07Just don't put
00:50:08your device on max.
00:50:10There's one trick
00:50:11you can use
00:50:12to make salt and pepper
00:50:13come out smoothly.
00:50:14Grab a container
00:50:15with pepper or salt,
00:50:17turn it upside down.
00:50:18There are ridges
00:50:19on the bottom
00:50:20of the shaker.
00:50:21Now, grab the second container
00:50:23and rub those ridges together.
00:50:25The vibrations
00:50:26will make the product
00:50:27literally flow out.
00:50:29Most headphones,
00:50:31both wired and wireless,
00:50:32have little holes.
00:50:34They're needed
00:50:34to ensure good sound.
00:50:36The air circulates
00:50:37through those holes,
00:50:38which is important
00:50:39for the sound quality.
00:50:41Stick sachets
00:50:42were designed smartly.
00:50:45No need to tear
00:50:46one of its edges.
00:50:47The right way
00:50:48is to tear them
00:50:48down the middle.
00:50:49Now, you may say
00:50:51it's not a big difference,
00:50:52but at least there's less mess
00:50:54with those torn paper bits.
00:50:56If two zips
00:50:57for one section
00:50:58seem a bit too much
00:51:00for you,
00:51:00it's probably time
00:51:01you started using them wisely.
00:51:03It's a great pickpocket proof.
00:51:05You can put on
00:51:06a small lock
00:51:07on those zippers
00:51:08and make sure
00:51:09no one but you
00:51:10can open your backpack.
00:51:11Hide the key
00:51:12in the fifth pocket
00:51:13on your jeans
00:51:14that was originally designed
00:51:15to keep watches safe.
00:51:17So, now you know.
00:51:21So, grab your phone.
00:51:23Good.
00:51:23Now, turn it around.
00:51:25You see that little dot
00:51:26between the camera
00:51:27and the flash?
00:51:28That's a tiny microphone.
00:51:30Bet that's something
00:51:31you didn't know.
00:51:32What's it doing there?
00:51:33Well, when you're
00:51:34on a phone call,
00:51:35this little guy
00:51:36is busy at work
00:51:37reducing the amount
00:51:38of background noise
00:51:39other people hear
00:51:40when you talk.
00:51:41That's right.
00:51:42If it wasn't for this,
00:51:44calls wouldn't be
00:51:45as nearly as crisp
00:51:46as they are now.
00:51:48You're lost in the woods
00:51:49and you're rushing
00:51:50to get back to camp.
00:51:52You suddenly remember
00:51:53you've got something
00:51:54that can help.
00:51:55You grab one of your
00:51:57chest straps
00:51:57from your backpack
00:51:58and whistle on it.
00:52:00Yup, that's right.
00:52:02A lot of bags
00:52:03have this feature in them,
00:52:04especially the ones
00:52:05made for the outdoors.
00:52:07It isn't long
00:52:08before you hear
00:52:08the call
00:52:09of one of your friends
00:52:10and you follow them
00:52:11back to the warm
00:52:12campfire,
00:52:13saved by this
00:52:14cool bit of design.
00:52:16If you're a curious person,
00:52:18you might have wondered
00:52:19what that little pocket
00:52:20in your jeans
00:52:21is doing there.
00:52:22You know,
00:52:23the one that's
00:52:23inside the bigger pocket?
00:52:25People often use it
00:52:26to store coins
00:52:27and bills,
00:52:28but it's not meant
00:52:29for that.
00:52:30It's actually designed
00:52:31to store your pocket watch
00:52:32safely.
00:52:33Huh?
00:52:34Maybe that's where
00:52:35the name pocket watch
00:52:36comes from?
00:52:39You finally arrive home
00:52:40after a long day's work.
00:52:42You understandably
00:52:44don't feel like cooking,
00:52:45so you sit on the couch
00:52:46and watch a bit of TV
00:52:48and order some takeout.
00:52:49How about Chinese?
00:52:51Ah, perfect.
00:52:52There's the doorbell.
00:52:54That has to be your food!
00:52:55It smells delicious!
00:52:57Wait!
00:52:58Before you grab the plates,
00:52:59do this instead.
00:53:01Open your Chinese food
00:53:02container on the table.
00:53:03It becomes the perfect plate,
00:53:05and it's cardboard,
00:53:07which means
00:53:08no cleaning either.
00:53:11The can of soda
00:53:12you got with your food
00:53:13has a cool feature too.
00:53:15Look at the tiny
00:53:16metal tab there,
00:53:17the one you used
00:53:18to open the can.
00:53:19Guess what?
00:53:20You can fit your straw
00:53:21in there.
00:53:21In fact,
00:53:22that's exactly
00:53:23what they're made for.
00:53:24Go ahead,
00:53:25try it for yourself.
00:53:28If you're not
00:53:29at your computer,
00:53:30take a look
00:53:30at your keyboard
00:53:31right now.
00:53:31If you're not,
00:53:32that's okay.
00:53:33Here's one on the screen.
00:53:34The keycaps
00:53:35are arranged
00:53:36in what's called
00:53:37the QWERTY layout,
00:53:38named after
00:53:39the first six keycaps
00:53:41below the numbers.
00:53:42As it turns out,
00:53:43it wasn't always this way.
00:53:45They used to be
00:53:45laid out alphabetically,
00:53:47which would make more sense
00:53:48when you think about it.
00:53:49The alphabetical layout
00:53:51fell out of use
00:53:52because long ago,
00:53:53there were things
00:53:54called typewriters.
00:53:56Remember those?
00:53:57You press down a key,
00:53:59and a type bar
00:54:00would fly out,
00:54:01hitting an inked ribbon
00:54:02and stamping a letter
00:54:03on the piece of paper.
00:54:05Eventually,
00:54:06typists got good at this
00:54:07and typed faster.
00:54:09Too fast.
00:54:10The typebars would eventually
00:54:11get caught in a log jam
00:54:13with each other,
00:54:14ruining the flow.
00:54:15To fix this problem,
00:54:16they made keyboards
00:54:17with randomized keycaps.
00:54:19The new layout
00:54:20actually worked better
00:54:21because it made typing harder,
00:54:23helping to slow typists down
00:54:25and prevent the typebars
00:54:26from getting stuck.
00:54:28Much better!
00:54:29Today,
00:54:29no typebars,
00:54:30no typewriters,
00:54:31mostly.
00:54:32People are still fast nowadays,
00:54:34but you just can't help
00:54:36but wonder
00:54:36who was faster though,
00:54:38us or them.
00:54:39Keyboards have another
00:54:40hidden feature too.
00:54:42Have you ever noticed
00:54:43that the F keycap
00:54:44and the J keycap
00:54:45have little bumps
00:54:46on the bottom of them?
00:54:47As it turns out,
00:54:48they're there to help people
00:54:50figure out where they are
00:54:51on the keyboard
00:54:51without having to take
00:54:53their eyes off the screen.
00:54:56Grabbing a takeaway cup of coffee
00:54:57at your favorite cafe
00:54:58might be just what you need
00:55:00to fully wake up
00:55:01in the mornings.
00:55:02When you get back home
00:55:04or to work though,
00:55:05you might be afraid
00:55:06to stain your desk
00:55:07when you put
00:55:07the steaming hot coffee down.
00:55:10Worry not,
00:55:11your plastic lid
00:55:12isn't only good
00:55:13for keeping your coffee hot,
00:55:14it also doubles as a coaster.
00:55:17In fact,
00:55:17they're the perfect size
00:55:18to hold a cup.
00:55:19Try it for yourself.
00:55:22This one's gonna come in handy
00:55:23if you're a home cook.
00:55:25If you're like me,
00:55:26you might have a bit of trouble
00:55:28deciding how much pasta
00:55:29you need for just one serving.
00:55:31Well,
00:55:32if you've got a pasta scoop,
00:55:33grab that.
00:55:34Most people don't know
00:55:35what the little hole
00:55:37in the middle is for
00:55:38and assume it's supposed
00:55:39to help with water drainage
00:55:40or something.
00:55:41It turns out
00:55:42that it helps you
00:55:43measure out a perfect serving.
00:55:45Just see how much dry spaghetti
00:55:47you can fit in the hole
00:55:48and use that as one portion.
00:55:52Out of the store
00:55:53buying coat hangers,
00:55:55you might notice
00:55:55that the plastic ones
00:55:56feel cheaper
00:55:57than the wooden ones.
00:55:58There's a good reason for this.
00:56:00Wooden hangers
00:56:01are made out of cedar wood.
00:56:03The big difference
00:56:04between the two
00:56:05is that the wooden ones
00:56:06repel bugs and moths.
00:56:09They're stronger
00:56:10and last longer too.
00:56:11Perfect for things
00:56:12that might stay
00:56:13in your closet
00:56:14for a long time.
00:56:16When you brush your teeth,
00:56:18you might have noticed
00:56:18that your toothbrush
00:56:19has blue bristles.
00:56:21They're not just there for show.
00:56:22In fact,
00:56:23they're there to tell you
00:56:25when it might be time
00:56:26to switch toothbrushes.
00:56:27These bristles
00:56:28lose their strength
00:56:29and color
00:56:30when the brush
00:56:31has been worn down,
00:56:32letting you know
00:56:33that it's time
00:56:34to get rid of it.
00:56:36Microwaves
00:56:37often look a bit
00:56:38like mini TVs,
00:56:39especially ones
00:56:40where you can clearly see
00:56:42the black film around them.
00:56:43This is actually
00:56:44a really important feature
00:56:45that's used
00:56:46to keep the radiation
00:56:47from slipping away.
00:56:49They're called
00:56:49Faraday cages,
00:56:51if you want
00:56:51to get technical.
00:56:52This is why
00:56:53you can stand
00:56:54next to a microwave
00:56:55without melting
00:56:56into a puddle.
00:56:58That's not to say
00:56:59you should stand
00:56:59in front of the microwave
00:57:01and watch your food heat up,
00:57:02but at least you know
00:57:04you won't grow
00:57:04an extra ear or something.
00:57:06Okay, not really.
00:57:08Some ovens
00:57:09have a drawer under them.
00:57:10It's tempting to use this
00:57:11to store random junk
00:57:13you don't use often,
00:57:14but there's a better use for it.
00:57:16Instead,
00:57:16this should be used
00:57:17to help keep the food
00:57:18that's waiting
00:57:19to be served hot.
00:57:21You can take it out
00:57:22of the oven
00:57:22and store it
00:57:23right in this drawer,
00:57:24keeping your oven free
00:57:25for you to carry on cooking.
00:57:28Now,
00:57:29you're on a plane
00:57:30looking around
00:57:30trying to pass the time
00:57:32before takeoff.
00:57:33When you examine the window,
00:57:34you notice this has
00:57:35a little,
00:57:36very tiny hole
00:57:37on its bottom.
00:57:38Don't worry,
00:57:39it's not broken.
00:57:41It's there to relieve
00:57:42the pressure
00:57:43that builds up over time
00:57:44as the plane
00:57:44goes up and down.
00:57:46It also lets the air
00:57:47flow through it.
00:57:49Now,
00:57:49raise your hand
00:57:50if you've ever ridden
00:57:51on an escalator
00:57:52and scrubbed your shoes
00:57:53on its bristles.
00:57:54Hey,
00:57:54I'm guilty of doing that.
00:57:56Maybe more than I should.
00:57:57It's not there
00:57:58to clean your shoes, though.
00:57:59It's an important
00:58:00safety measure.
00:58:02It stops your shoelaces,
00:58:03clothing,
00:58:04and other stuff
00:58:04from getting stuck in there,
00:58:06avoiding a nasty scene
00:58:07when you go to get off.
00:58:10Sometimes a piece of fabric
00:58:12comes with your new clothing.
00:58:13It usually comes along
00:58:15with the extra buttons
00:58:16in a little plastic bag.
00:58:17You might think
00:58:18it's just a piece of fabric
00:58:20to use for future patching,
00:58:21in case you rip it.
00:58:23But that isn't its purpose at all.
00:58:25It's actually supposed
00:58:26to be put in the washing machine
00:58:28to test how it reacts
00:58:29to various washings.
00:58:31Now,
00:58:31you don't have to worry
00:58:32about shrinking
00:58:33your new expensive coat
00:58:34because you know
00:58:35how it'll react to the wash.
00:58:38Bubbles!
00:58:38Who doesn't love bubbles?
00:58:40Most people have fond memories
00:58:41with bubble blowers as a kid.
00:58:43But as adults,
00:58:44the closest thing
00:58:45we can get
00:58:46to recapturing that feeling
00:58:47is with bubble baths.
00:58:49After a hard day at work,
00:58:51there's nothing better
00:58:52than dipping into
00:58:52a nice warm bubble bath.
00:58:54Right, guys?
00:58:55And the bubbles
00:58:56do more than just clean you.
00:58:58If they're high-quality bubbles,
00:59:00they'll serve
00:59:01as a heat insulator.
00:59:02So they make sure
00:59:03that your bath
00:59:04stays warm for longer.
00:59:07Boxes of chocolate
00:59:08sometimes have
00:59:09these mysterious holes in them.
00:59:11When I'm eating a box,
00:59:12or two,
00:59:13I usually ignore them
00:59:14and take out the chocolate
00:59:16by pressing
00:59:16the bottom of the plastic.
00:59:18But it turns out
00:59:19that I've been doing it
00:59:20wrong the whole time.
00:59:22If you press one of the holes,
00:59:24the chocolate comes right out.
00:59:26I'm certainly going to start
00:59:27doing this from now on.
00:59:30Here's another one
00:59:31from the kitchen.
00:59:32The handle on a pot
00:59:34will often have a hole in it.
00:59:36Most people use this
00:59:37to hang them on a nail
00:59:38on the wall
00:59:39as an easy storage method.
00:59:41The hole has another use, too.
00:59:43When you're cooking,
00:59:44you can use this handle
00:59:45to hold your wooden spoon
00:59:47or whatever else
00:59:48you might be cooking with.
00:59:49This makes sure
00:59:50you don't make a mess
00:59:51when you put it down.
00:59:54Glass bottles
00:59:55usually come with a cap in them.
00:59:57Well, duh!
00:59:58Otherwise,
00:59:59the liquid would just spill.
01:00:00In this cap,
01:00:01there's a plastic liner
01:00:02that seemingly
01:00:03has no purpose, right?
01:00:05Wrong.
01:00:06It's a seal!
01:00:09No, not a seal.
01:00:10A seal!
01:00:11It's the kind
01:00:12that helps keep
01:00:13your drink fizzy.
01:00:14Ah,
01:00:15just the refreshment
01:00:16I needed.
01:00:17A lot of doorknobs
01:00:19are made out of brass,
01:00:20and it's not by chance.
01:00:21They're made out
01:00:22of this specific material
01:00:24because it's bacteria's
01:00:25worst enemy.
01:00:26That's right,
01:00:27it destroys them.
01:00:28Perfect for those
01:00:29who want to keep
01:00:30a clean house
01:00:31and avoid germs.
01:00:32Hey,
01:00:33you want to fish?
01:00:34No!
