00:00You know how they say, when in Rome, do as the Romans do?
00:03Meaning, in Rome, you need to make sure your goldfish has a deluxe bowl to live in.
00:09In Nigeria, don't you dare to bring your own wheelbarrow.
00:13And perish the thought of adding as much mayo as you want to your dish when you're in France.
00:19Yep, bands around the world may be surprising, to say the least.
00:23Number 1. You will never see a good old doorknob in Vancouver, Canada.
00:28Some time ago, the city changed its building code to require the use of cool and sleek door levers instead.
00:34This change is all about making buildings more accessible and easier to use.
00:39Not only new buildings are getting a new makeover.
00:41Even Vancouver's historic city hall had its fancy Art Deco doorknobs replaced with shiny gold levers.
00:49But it's not that you can't legally have it in your house.
00:51There isn't a team of doorknob police coming to your house to confiscate your knobs.
00:56You can keep them as long as you like.
01:00Number 2 comes with a geoguesser tip for y'all.
01:03If you see this chair in the picture, it means it's 100% not in Basel, Switzerland.
01:09It's called a monoblock chair, and it's special.
01:12You see, most objects give away clues about when and where they're from,
01:16like the shape of electrical outlets or the labels on your shampoo bottle.
01:20But the monoblock is context-free.
01:23Some people call them one of the world's most perfectly designed objects,
01:26while others say the homogenous nature of the chair is disturbing and the real evil of globalization.
01:33But why is it banned in Basel?
01:35Turns out the authorities just want the city to be pretty, and the chair design isn't to their liking.
01:41Right.
01:41If you want to keep one in your backyard, feel free.
01:473. If you were ever thinking of bringing a wheelbarrow to Nigeria, I've got some news for you.
01:57Don't even try.
01:58Should you need it for some reason during your stay in Nigeria, just buy one there when you arrive.
02:03The authorities won't let you bring your imported wheelbarrow across the border.
02:07Why?
02:08Well, they're all about supporting their own manufacturing industry.
02:12So they want to give their local wheelbarrow makers a chance to shine.
02:17At number 4, we've got China, where the authorities decided to put a stop to time travel.
02:23Wait a minute. It's not what you think.
02:25No time travel machine has been invented.
02:28The ban is on TV shows and movies.
02:30By the way, it's not something new.
02:32The law was introduced in the early 2010s.
02:35Apparently, the big shots in charge want to keep things real and are not too keen on distorting historical events.
02:42They say some scripts are getting a bit too wild, making up myths, promoting superstition, and disrespecting the country's past.
02:515. Coffee pods
02:53They've become super popular because they make brewing coffee so easy.
02:57But Hamburg, Germany doesn't seem to be a fan of those pods.
03:00Around 8 years ago, they took a stand by banning plastic coffee pods from authorities' offices.
03:06These little pods are made of various materials, making recycling a real challenge.
03:11While it's true that these coffee capsules can create a lot of problems, they're still loved by many.
03:17In fact, they've become a big hit in the US and Europe, making up a chunk of the coffee market.
03:23Hamburg is hoping to lead the way in showing people just how wasteful these pods really are.
03:29Number 6. Chewing gum
03:31It has been banned in Singapore since 1992.
03:34The ban was put in place to stop people from sticking gum in all sorts of weird places,
03:39like subway doors, lock cylinders, and elevator buttons. Yuck!
03:44But costly train shenanigans were the last straw for the authorities.
03:48The ban was put in place after some serious gum incidents on the mass rapid transit or MRT trains in
03:55the late 80s.
03:55Some mischievous or mischievous pranksters have been gumming up the words on MRT trains by sticking chewing gum on the
04:02door sensors.
04:03That caused a sticky situation and messed up train services.
04:07And there you have it. Chewing gum got completely banned.
04:11Now, just a note here.
04:12Yep, these are gums prescribed for therapeutic or dental reasons.
04:16And yep, they're still allowed.
04:18Also, don't get this whole ban wrong.
04:20It's not illegal to chew gum in Singapore.
04:23So if you come there as a tourist, you can bring in a little gum for personal use if you're
04:27traveling.
04:28Just do not stick it under this nice park bench, okay?
04:32What will create you a ton of troubles, though, is importing and selling chewing gum.
04:39Iceland is number 7 in our ban hit parade.
04:43Back in 1994, Reykjavik was like, no dogs allowed.
04:46It wasn't because they were all about cats.
04:49It was to stop this nasty tapeworm from spreading.
04:52The disease was serious business, causing all sorts of health problems.
04:56But don't worry.
04:57Dogs are cool now as long as they follow the rules.
05:00Nowadays in Reykjavik, it's all about the cats.
05:03They're everywhere, roaming the streets like they, you know, own the place.
05:07You can't walk two steps without seeing a furry little friend begging for attention.
05:12These Reykjavik kitties are so popular that they even have their own Facebook page.
05:17People love them.
05:18And some even carry around treats just in case they come across a friendly feline.
05:23And since there aren't many threats to cats in Iceland, they're thriving.
05:288.
05:29The Philippines
05:30Now, this one is really weird.
05:32Singing my way in karaoke bars is sort of banned in this country.
05:36This seemingly harmless song has been linked to some pretty serious consequences,
05:41like fistfights and even people's early demise.
05:44No one knows the exact number of lethal cases caused by this song,
05:48but there have been at least a handful of incidents in the last 10 years.
05:52The song's lyrics, which can come off as a bit arrogant and prideful,
05:56seem to rile people up when sung in a not-so-great way.
05:59This has led some karaoke bars to unofficially ban the song to prevent any craziness from breaking out.
06:089.
06:09Hey, have you heard about Japan's Metabo Law?
06:12It's all about measuring waist sizes to tackle obesity.
06:15It was introduced in 2008, and the idea was that if companies and local authorities didn't meet the goals,
06:22they would face financial penalties.
06:24The Ministry of Health believed this campaign would help prevent various health conditions.
06:29So, every year, people aged 40 to 75 had to get their waist measured.
06:34Employers and local authorities needed to make sure at least 65% of people participated.
06:40The goal was to reduce Japan's obesity rates by 25% by 2015,
06:45and if they hadn't made it, they would have gotten slapped with a fine.
06:49Did it work?
06:50Well, in 2024, there are only 4.5% of people who reportedly have weight issues in Japan.
06:58Number 10, and we're back to Canada.
07:01So, if you catch someone in there counting out pennies in line,
07:04you can totally have some fun with them, legally speaking, of course.
07:08According to the Canadian Currency Act,
07:10there's a limit to the number of pennies you can use in a transaction.
07:1425, to be exact.
07:15So, if someone tries using 26 coins,
07:19you can play sheriff and send them to coin jail.
07:22Snatch up their pennies as evidence.
07:24Yeah.
07:2511, and a condiment-regulated country here.
07:28Apparently, in France, they're cracking down on condiments in public schools.
07:33They're trying to make meals healthier for students.
07:36The rule is that you can't just go crazy with mayo, ketchup, and vinaigrette anymore.
07:41They have to be served according to the dish.
07:45Finally, Italy.
07:46In Rome, you can't keep your goldfish in a boring old glass bowl.
07:51Nope, that's considered cruel, because those little guys need their oxygen flow.
07:55Plus, if you keep them in a bowl for too long, they might go blind.
07:59Also, you can't give away goldfish's prizes.
08:02The law has a whole subsection about it.
08:04So, if you're planning on bringing a goldfish home from your next trip to Rome,
08:09make sure you've got a fancy tank ready for them.
08:11And thank you for watching!
08:16You know what?
08:17Onions can help fight off the flu.
08:19Hmm.
08:20And apparently, they can do it in various ways.
08:22Like, you can put them in your socks, which somehow transfer their disease-fighting abilities
08:27through your feet.
08:28Or you can drink onion-infused water to treat or prevent illnesses like colds or the flu.
08:34Well, unfortunately, these are all false beliefs.
08:37When it comes to directly combating cold or flu viruses, onions are unlikely to have a superimpact.
08:43But overall, they're good for you.
08:45At the same time, onions do have a high concentration of quercetin.
08:50It's a pigment known for its potential anti-inflammatory properties.
08:55The correct way to open a new deodorant is by manually prying the top off.
09:00Nope.
09:01Removing the cap from a new deodorant stick involves twisting it.
09:05This move triggers the mechanism to push the safety cap off.
09:09This method helps avoid the hassle of manually prying the lid off,
09:13leaving deodorant residue under your nails.
09:16Now, what about the ideal time for using deodorant?
09:19You might think it's in the morning before you leave the house.
09:22But the optimal time to use deodorant is in the evening.
09:26At this time, your body temperature is cooler and your underarms are less moist,
09:30providing a greater opportunity for the deodorant to work effectively on your skin.
09:35Applying deodorant in the morning is still okay for those people who don't suffer from excessive sweating.
09:40So, if you sweat a moderate amount, there's no reason to change your daily routine.
09:46Now, keeping your shower curtain inside or outside the tub is a choice.
09:50But, apparently, putting the shower curtain inside the tub reduces splashing and prevents water from escaping.
09:57The decorative cloth curtain belongs on the outside, whereas the plastic one should be on the inside.
10:02I mean, the whole idea is to prevent splashing water.
10:07Now, watering your plants on scorching hot days harms them.
10:11Mmm.
10:11Rain showers occur during the summer season all over the world, and plants easily survive in these conditions.
10:17At the same time, when you water your plants on hot days,
10:21a substantial amount of liquid might evaporate before it can effectively benefit the plants.
10:26It's worth noting that this might be different for some sensitive indoor plants, such as African violets.
10:32It can result in leaf damage if you pour very cold water directly onto their leaves.
10:38Now, let's continue with another garden-related thing.
10:41Tree roots only reach as far as the outer edge of tree branches.
10:45Myth or fact?
10:46Well, it's a misconception.
10:48The root systems of many trees can extend well beyond the diameter of their crowns.
10:53For instance, magnolia trees can have roots that reach nearly four times their crown diameter,
10:59while the roots of red maple trees can exceed their crowns by up to three times.
11:04It's easier to shuck corn before it's boiled.
11:07Well, in the past, before the invention of modern cooking methods, many recipes involve pre-shucked corn.
11:13However, you can still grill it with or without the husk when it comes to recipes like grilled corn.
11:19A recommended technique is to partially shuck the corn, leaving only a few layers closer to the cob still attached.
11:26This method retains moisture while also providing appealing char marks on certain kernels.
11:32Alternatively, you can cook whole, unshucked ears of corn in the microwave or by boiling it, if you prefer.
11:40Moving on with everyday items you've been storing wrong.
11:44Take eggs, for example.
11:46Leaving them in the fridge door is good for them, right?
11:49No, this can lead to a rollercoaster of temperatures every time you grab a snack.
11:54As for nuts, they're happier in the fridge.
11:56He can make them go all wonky, especially if they're the kind with lots of good fats.
12:01So, keeping them chilled helps them stay fresher and tastier.
12:06There's another common myth about nuts.
12:08It's said that roasting them decreases calories, proteins, carbs, and fibers they contain.
12:14But no, both cooked and uncooked nuts have similar amounts of those.
12:18The main goal of roasting nuts is to enhance their flavor and crunchiness.
12:22Keep this in mind, though.
12:24When nuts are roasted, the healthy fats they contain may get damaged.
12:28And in the end, this can result in a reduced nutrient content.
12:32Now, let's talk about avocados.
12:35Don't toss them in the fridge if you want them to ripen on schedule.
12:39Feel like hanging out at room temperature.
12:41We can also put an end to another avocado-related myth.
12:45Avocados are fattening.
12:47Yeah, they do have a high-fat content, compared with most other fruits.
12:51But this doesn't necessarily make them bad for your health.
12:54In fact, avocados contain what's often called healthy fats, which can help reduce harmful cholesterol levels in your body.
13:02Now, let's carry on with diet and food.
13:05Swapping white table sugar for unrefined options like honey, maple syrup, and coconut sugar is supposed to make your diet
13:12healthier.
13:12Well, don't fall for this myth.
13:15Sugar is sugar, no matter whether it's refined or unrefined.
13:19While unrefined sugars may contain a few extra vitamins and minerals, the advantage is minimal, because they're still considered added
13:27sugars.
13:27These added sugars can add up and contribute to your diet's recommended limit on daily sugar intake.
13:34Full-fat products aren't a one-way ticket to weight gain.
13:38That's a myth from the 80s and 90s.
13:40Some people are still scared of fat, but it shouldn't be the case.
13:44Fat plays a few essential roles, such as protecting our organs, maintaining cell membranes, supporting health and development, and helping
13:52absorb vital vitamins.
13:53The key is to choose heart-healthy unsaturated fats, like olive oil, canola oil, nuts, nut butter, and avocados,
14:02oversaturated and trans fats found in fatty meats and high-fat dairy products.
14:08There's a common belief that avoiding carbs entirely will make you lose weight.
14:12Well, that's a myth, too.
14:14Low-carb diets have made their rounds, vilifying carbs, including fruits and whole grains.
14:20While some people have had success with these diets, it's usually because they've cut out highly processed, carb-laden foods,
14:27like chips, cookies, and white bread.
14:29You know, all the stuff we like.
14:31Eliminating an entire food group isn't the best approach, as you might miss out on essential nutrients.
14:37Another belief is that you can get rid of body toxins with a detox diet.
14:42Well, sorry, most detox diets don't live up to their promises.
14:46Your body is already good at detoxing itself with the help of your liver, kidneys, and gastrointestinal tract.
14:52You don't need to buy any special products.
14:55If you want to rejuvenate your body, focus on eating more whole foods, staying hydrated, and cutting out highly processed
15:03junk food.
15:05Okay, I have three life hacks for you.
15:07These aren't myths.
15:09Firstly, you can stop a pot from boiling over by putting a wooden spoon over its top.
15:14Secondly, if you position a cheese grater vertically, there's a better way to use it.
15:19Lay it down horizontally.
15:21This way, the process will be less taxing for your arms.
15:25My next tip is about your yoga mat.
15:27Leaving it in a hot, humid spot like your car can ruin it.
15:31Keep it cool and dry for maximum yoga zen.
15:35Now, many people know they should keep their fancy fragrance bottles away from direct sunlight.
15:40So, some people store them in the refrigerator.
15:43This isn't the right move, unless you want your perfume to lose its overall depth.
15:48I mean, yes, fragrances don't like heat or humidity, but the interior of a refrigerator is too dry and cold
15:56for them.
15:56So, it has the opposite effect and breaks down the scent molecules.
16:00And please, resist the urge to rub a bit of perfume on your wrist.
16:04It may be tempting, but rubbing your fragrances is a big no-no.
16:09This practice not only muddles and weakens the scent, it also causes the top notes to evaporate quickly.
16:17They say that if you have old photos in your house, the right way to stash them is by putting
16:23them in cardboard boxes.
16:25Well, this is a misconception.
16:27These types of boxes can damage your memories.
16:30Go for acid-free archival boxes if you want your pictures to look as good as new.
16:35The next one is more of a hack than a myth.
16:38It turns out dishwashers are more user-friendly than we give them credit for.
16:42When you're loading or unloading the dishwasher, you can save your poor back from unnecessary strain by pulling out the
16:49basket.
16:51You might think that foundations are safe at room temperature.
16:54But if you store your foundation in a makeup bag, heat can mess with the oils in your makeup.
16:59So, pop this product in a cool drawer.
17:02Eye creams and serums can benefit from the chill, too.
17:06Organic or homemade cosmetics without preservatives should also be refrigerated.
17:11But always check expiration dates.
17:13I know I do.
17:17You see these blades?
17:19They have notched corners to make your cutting experience smoother.
17:22Ooh.
17:23The front edge notch helps with separating blades during manufacturing.
17:27While the trailing edge notch helps the blade glide easily.
17:31And a fun fact.
17:33That notch on the front also helps you spot unused sections of the blade.
17:37Just a little visual indicator to make your life easier.
17:41When it comes to silver versus black blades, they're both made from the same stuff.
17:45But black blades are sharper and are better suited for cutting through tough materials.
17:50While silver blades strike a balance between cutting power and durability.
17:54If you want that extra cutting, oomph, go for black.
17:59Oh, almost forgot.
18:00The only thing those blades aren't meant to cut is food.
18:04It has a rust-proofing oil coating, which is not safe for humans.
18:09Check this one out.
18:10It's totally giving me childhood vibes.
18:13Now, I remember my grandma having tomato-shaped pin cushions just like this.
18:18And sometimes they would look more like a salad, with a little pepper thrown in there.
18:22Well, believe it or not, this salad actually has a purpose.
18:26The tomato keeps your pins in place, while the pepper keeps them sharp.
18:31Those peppers are filled with sand, which helps keep your pins nice and sharp.
18:36And it's not just sand.
18:37Crushed walnuts can also be used to keep your pins in tip-top shape.
18:43Now, look at this multiple-pocket tool and this little hook on it.
18:47It's a bit of a mystery, but it's actually pretty handy.
18:50I counted at least four different applications.
18:53One, you can use it to carry all sorts of awkward stuff, like camping gear or heavy parcels.
18:59Two, need to twist some wire or play around with knots?
19:03The parcel hook has got you covered.
19:05Three, this hook can save the day with those stubborn zippers, like the ones on your luggage.
19:10Four, it's great for pretending to be a budget version of Captain Hook.
19:15If you know more applications, let me know in the comments.
19:20Apple users, with this feature, you'll never get laundry surprises again.
19:25Now, I bet you've had this situation at least once in your life.
19:28You wash your stuff, and when you take it out of the washing machine, the size seems to only fit
19:34your cat.
19:35Your iPhone camera can actually translate those funky laundry symbols for you.
19:39There are two requirements, though.
19:42You must have iOS 17, and your phone must be in English.
19:45Take a photo of the care label, go to the Photos app, and see the details of the image.
19:51Everything will be automatically decoded and explained to you.
19:56Now, many toasters come with nifty removable crumb trays at the bottom.
20:00It's super important to give these trays a good clean every now and then to keep your toaster running smoothly
20:06and avoid any potential fire hazards.
20:09Just pop them out, shake out the crumbs, and you're good to go.
20:13Where you shake them out is up to you.
20:15Those little compartments on your gas pump aren't just for show.
20:19They're actually there to hold your cap while you're filling up.
20:21This nifty feature keeps things tidy and prevents any spills or drips on the handle.
20:27So, say goodbye to messy refueling experiences and hello to a cleaner pump.
20:33Plus, it makes the whole process way more convenient and efficient.
20:38Now, I'll bet your oven gets so greasy and dirty sometimes that you can even hear it oink.
20:44Just kidding.
20:45I know you're a tidy person.
20:47Anyway, if you're looking for a way to bring your kitchen cleaning to a whole new level, here's a tip
20:52for you.
20:53Most oven doors have handy latches that let you pop the door off for easy cleaning, saving your poor back
21:00from the strain.
21:02When you're draining noodles or potatoes, there's no need to bother transferring everything to a colander in the sink.
21:09Just throw the colander right into the pot, hold it down, and pour the liquid out.
21:14It makes life so much easier, especially when you want to save that starchy water for recipes.
21:19It's a must for authentic pasta, by the way.
21:24So let's say you've snagged this gem at a thrift store a while back for just under a dollar.
21:29It's seen better days, serving as an ashtray, but you decide it's time to give it a new lease on
21:36life.
21:36Here's the lowdown on how to make it shine again.
21:39Mix up a solution of boiling water, baking soda, and table salt in a bowl lined with aluminum foil.
21:47Let the piece soak for about 15 minutes and repeat this process three times.
21:52In between soaks, gently scrub any rough spots with a microfiber cloth.
21:57After the final soak, dry the piece off and rub on some toothpaste, baking soda, and peroxide.
22:04Buff out any remaining tarnish with a clean, dry microfiber cloth.
22:08Rinse it off, and now your piece is practically gleaming like a mirror.
22:14These aluminum foil boxes have nifty little tabs on the sides that make it super easy to grab a sheet
22:20without any hassle.
22:22It's like a fancy little bonus that makes the product a breeze and ensures you'll have a smooth sailing experience
22:29every time.
22:31Manual can openers often come with a handy built-in feature, also known as a bottle opener.
22:36It's like getting two tools in one.
22:39But did you know that this bottle opener actually has another useful function?
22:44It can help you loosen those stubborn, hard-to-open jars.
22:48Simply lift the lid slightly at a couple of points with the bottle opener,
22:52and then watch it as it effortlessly twists right off.
22:56Yeah!
22:58Okay, I just found that, apparently, you're supposed to save the first and last slices of a loaf of sliced
23:04bread for last.
23:05It's like a bread hack or something.
23:08Apparently, those end pieces help keep the rest of the bread fresher for longer,
23:12and you shouldn't eat them until you've devoured the rest of the loaf.
23:15So, next time you're making a sandwich, save those heel slices for the very end.
23:20Even bread-eating needs a good strategy.
23:23Now, look at those blue levers on the top rack of your dishwasher.
23:27I was curious about them, too.
23:29And it turns out they are actually water bottle sprayers.
23:33They help to ensure that your bottles get a thorough cleaning and rinse during the wash cycle.
23:39Many vegetable peelers have those little scoops on top for taking out the eyes from potatoes.
23:45And here's a cool tip.
23:46You can actually use vegetable peelers in both directions to peel faster.
23:51But most people just stick to one direction.
23:55When using yellow mustard, make sure to push the lid of the bottle all the way open until you hear
24:01a satisfying click.
24:02This way, the lid will stay securely in place and won't get in the way when you're dispensing the mustard
24:07onto your food.
24:08It's a simple step that can make your condiment experience hassle-free and enjoyable.
24:14So there!
24:16You know that little hole at the end of your pot or pan?
24:19Well, it's not just for show.
24:21You can actually use it as a handy holder for your forks and spoons.
24:26Next time you're cooking up a storm in the kitchen, just pop your utensils in that convenient little hole and
24:32keep them close at hand.
24:35Okay, just a heads-up to remember to switch the direction of your ceiling fan for the changing weather and
24:41to give it a good clean, too.
24:43I've seen that a lot of folks found it helpful before to reverse the fan's direction by flipping a switch
24:49for different seasons.
24:50So this is just a friendly reminder to go ahead and do it again, pushing hot air down and pulling
24:56cold air up.
25:00When you're chowing down for some pizza, just tear off the top of the box and use it as a
25:05big old plate.
25:06You can even rip the box in half and fold it to save some leftovers for later.
25:11Well, that's it for today.
25:13What, you want to know more cool facts?
25:15Sure, but you'll have to subscribe and hit the bell to get more videos.
25:19I'm waiting.
25:20Go ahead.
25:25There are some inventions that make us say, dude, why didn't I come up with this?
25:30And then you have the next question.
25:32Why don't we have it in my hometown yet?
25:35I'm talking about things like splash-proof toilets, liquid trees, and skyscrapers with slides.
25:42Yep, they're all pretty real, and you're about to fall in love with them.
25:48Have you ever used a public bathroom in the summer in your shorts and sandals and got splashed?
25:54It happens to the best of us, so no worries.
25:57If only there was some solution to this problem.
26:00Perhaps a urinal with a small hole so no liquid goes where it shouldn't.
26:05Looks pretty yucky and painful to me.
26:08An assistant professor at the University of Waterloo,
26:11Zhao Penn and his colleagues came up with a way better solution for this sensitive issue.
26:17Their designs were inspired by physics and dogs.
26:21When a stream of liquid moves on a solid surface at a shallow angle, the splash is reduced,
26:27and the smaller the angle, the fewer splashes you'll see.
26:30You can even minimize them to a zero.
26:32And when dogs do their business, they lift their hind legs and do it on the vertical surface of a
26:38tree or a wall.
26:39I don't know if they actually care about it, but this does reduce the splash.
26:44Good job, Pluto!
26:46The team invented several models and presented them at the American Physical Society conference,
26:51and it was a hit.
26:53The inventors say that all of the models are no splash,
26:56but their favorites are the slice of apple and the one that looks like a tall and slender J with
27:02a narrow and long opening.
27:03The new urinals aren't just super cool, but also more sustainable.
27:08You won't have to wash the floor with water, chemicals, and human energy after every use, which is a win
27:15-win.
27:16Here's another innovative public toilet idea for you, this time from Japan.
27:22They have completely transparent walls, which means, yes, you can see everything that's going on inside,
27:28from the toilet itself to the hand wash sink.
27:31It sounds pretty creepy, but the idea was actually to create a safe restroom in the park.
27:37Visitors can see if there's someone hiding inside before entering, and also check if the toilet is clean before entering.
27:44When you go inside and lock the door, the walls change color to opaque, and no one will be able
27:50to see you.
27:51They used glass covered with PD-LC film to make the walls,
27:55which allowed them to go from being transparent to safely in tents using electricity.
28:01Alright, now you've nearly convinced me to try one of those magical toilets.
28:06Oh, and they also double as excellent lanterns in the dark, shining bright in different colors.
28:11Bring a couple to my local park, I don't mind.
28:15Take a deep breath.
28:16If you don't like what you're breathing in, do something about it.
28:20That must have been exactly what the smart guys at the University of Belgrade, Serbia thought and invented the liquid
28:26tree.
28:27The liquid tree, not the pun and laugh a bit,
28:31consists of a glass tank filled with over 150 gallons of water,
28:36some microalgae, and a solar panel, which provides electricity to a small pump.
28:41The microalgae need heating, so just in case there's no sun and the temperatures drop,
28:46the photobioreactor is also connected to the city grid.
28:51Microalgae work hard to do some photosynthesis magic and convert water and CO2 into oxygen,
28:57and then it goes into the atmosphere.
28:59The liquid tree also comes with a bench to sit on and enjoy its work.
29:04The liquid tree needs more work than a regular tree in the park.
29:07They need to replace the water and microalgae almost completely every month and a half.
29:13And they also need to take out the biomass that is the byproduct of the process,
29:18and let's admit, nothing can replace those blooming babes in spring.
29:23If you ever find yourself casually wandering in the forests of Estonia,
29:27don't freak out if you see some giant megaphones.
29:30These wooden, acoustic giants were set three hours away from the country's capital by interior architecture students.
29:38That's way cooler than the hamster roller coaster I once built for a science fair, I have to admit.
29:44More than half of Estonia is covered by woods, and they're pretty proud of this natural wealth.
29:49So it's not the first art project of this kind,
29:52and there was a winding, elevated pathway and a faceted woodland cabin.
29:56The idea of the megaphones is to crank up the natural sounds of a forest and also to serve as
30:03a rest spot for hikers.
30:05These wooden beauties are large enough to host several people.
30:09And hey, if you walk this far into the woodland, you'll be thankful for this.
30:14The students were given a task to invent some concepts of a forest library.
30:19They built the megaphones off-site and brought them to their permanent spots.
30:24They're set in such a way that sounds from three directions meet in the center
30:28and create a cool, natural surround sound effect.
30:32Have you ever helped your friends move into a new apartment in a building without an elevator?
30:37Then you're gonna love this one.
30:39Houses in Amsterdam have hooks on top.
30:42This is a medieval invention for pulling stuff up the houses.
30:46The simple tech consisting of a wheel and a rope still functions now, centuries later.
30:51Why not just use the stairs?
30:53Well, if you get inside one of those narrow Amsterdam buildings,
30:57you'll see there's hardly enough room to comfortably ascend,
31:01and you can forget about even trying to pull a table on top.
31:05Back in the medieval ages, pretty much like now,
31:08only rich people could afford housing around the canals in the best parts of the city.
31:13Those people were mostly traders and used the canals for their business.
31:17They stored goods in the same houses they lived in,
31:20and with regular floods, they had to find a way to keep the goods dry.
31:24And that's why they needed to invent something to lift furniture,
31:29goods, boxes, instruments, and food on the upper floors and pull it in through fully open, wide windows.
31:37The lifting tech is one of the reasons the houses in Amsterdam are leaning forward.
31:42This position helped keep both the lifted stuff and the walls and windows safe during transportation.
31:49They didn't have to touch each other.
31:51The gables also assisted in the process and had to be made firm to withstand all the heavy weight.
31:58And in case you're wondering what gables are,
32:01they're sections of wall between the edges of a dual-pitched roof, typical for Amsterdam.
32:07Folks who live or work in skyscrapers have the opposite problem.
32:12Getting out of the building can take a while as you wait in line for the elevator.
32:16A slide going from the top of a skyscraper could be a solution.
32:20In 2016, they added one outside of the U.S. Bank Tower in Los Angeles at the height of 1
32:26,000 feet.
32:28The see-through slide, made of glass just one inch thick,
32:31was built to withstand hurricane-force winds and earthquakes.
32:34It was built to bring tourists to the building, though not for the convenience of office workers.
32:40And then they decided it wasn't such a great idea,
32:43so the slide was removed as part of the reconstruction of the building.
32:48A Hong Kong photographer and editor who became famous online went even wilder with his imagination
32:54and designed a double-decker bus with a slide.
32:58It's not his only futuristic photography masterpiece,
33:01as he likes to play with perspective and proportions.
33:04I can totally see myself sliding away when someone asks me to pay for the ride.
