00:00You can never know what's big and what's small, what's clean and what's dirty, unless you compare it to something
00:06else.
00:07If it sounds a bit confusing, the internet is full of examples.
00:12Here's what a t-shirt turns into after 156 swimming lessons.
00:17I guess the person wearing it must be either an instructor or practicing for the Olympics.
00:24If your teeth were perfect since the day you were born, you probably have no idea what this one is
00:30even for.
00:32Meet Retainer.
00:33You're supposed to wear it after you take your braces off to keep your teeth straight.
00:38And if you don't want your retainer to look like this, try brushing it with a paste of water and
00:44baking soda on the inside and the outside.
00:47It should save your retainer from odors and bacteria.
00:51Here's what 8 months of intensive use can do to a pair of sneakers.
00:56I once saved my favorite shoes with a mix of baking soda and water.
01:01And I separately washed the shoelaces in a bowl of the same solution.
01:05Not sure if these sneakers here can be rescued though.
01:09The soles of your favorite pair of sneakers also need some love and care.
01:14Because they will otherwise look like this after just one year.
01:18So, from time to time, beat them together to remove clumps of dirt.
01:24Then, scrape what's left with a toothbrush.
01:27Finally, prepare a mixture of warm water and liquid dish soap and soak your shoes in this bath for 15
01:34to 20 minutes.
01:36Let them air dry on a clean, dry towel.
01:39And that's it!
01:41Okay, this one leaves us with a lot of questions.
01:45The owner of the case says they've been using it for 6 years.
01:50But, what on earth were they doing to turn it from crystal clear to this, uh, shade of brown?
01:56I guess I don't really want to know.
02:00Here's what can happen to ear pads after 3 years of enjoying music.
02:05If you don't want to replace your ear pads too often, you gotta take good care of the leather part.
02:11You can wipe your ear pads after use to get rid of skin moisture and sweat.
02:17Simply rubbing them against your t-shirt should do.
02:21You can also wipe them with a soft washcloth once a week.
02:25And never leave them in direct sunlight or extreme heat.
02:29This leather here is most likely artificial.
02:32And it's not designed to withstand high temperatures.
02:36Do you also have a plush friend that has been with you for your entire life?
02:40This monkey on the left is 17 years old.
02:44And this doodle bear on the right is even older.
02:48It just celebrated its 27th birthday.
02:51It's certainly got some character with time.
02:54If you don't want your beloved teddy to age, you can try giving it a spa treatment.
02:59Put it in a mesh laundry bag or zippered pillowcase.
03:03And choose the most delicate cycle your washing machine has.
03:07Make sure the water is cold or else your friend can change its color dramatically.
03:13Once it's done, wrap it in a towel and let it air dry.
03:18One internet user posted a picture of an apple from their local orchard compared to the one from the grocery
03:24store.
03:26Same story with this blackberry bought at a store versus a homegrown one.
03:30But does bigger mean better or more dangerous when it comes to fruit and veggies?
03:36Well, supermarket greens are often bigger and heavier than your homegrown produce,
03:41thanks to selective breeding and industrial fertilizers.
03:45But it doesn't mean they have more nutritional value or are healthier.
03:50Plus, they might be chemically treated to be stored longer and even travel to the other side of the world
03:56unharmed.
03:58Sometimes, size does matter.
04:00This difference between an egg from a two-year-old hen and a pullet just starting egg laying is so
04:06visible.
04:07I guess practice makes perfect.
04:10Which of these basketballs would you choose to play with?
04:14The new one sure looks better.
04:16But the five-year-old version has a history.
04:20Dollar bills used to be way larger in 1917.
04:24And here's the proof.
04:25A $1 bill normally circulates for around six years.
04:29It's the longest it can survive because it's made of a special cotton and linen blend
04:34and rarely sits in one pocket for a while.
04:37The $100 bill has a lifespan of 15 years before it goes back to the Federal Reserve.
04:45These wool blankets used to be twins 20 years ago.
04:49But then, they went their separate ways.
04:51One was well used and the other one was in storage.
04:55If you want your wool blanket to last longer and look great,
04:59refresh it every once in a while.
05:01Take it outside and shake it well before you hang it somewhere with good airflow.
05:06Lay the blanket flat on the floor and brush it with a soft bristle brush.
05:10If your blanket is machine washable, choose the gentle wool wash cycle,
05:16cold water, and special wash detergents.
05:19Don't hang it to dry in direct sunlight.
05:22It can dry too quickly, fade, and become coarse.
05:26And the dryer is an absolute no-go.
05:29Cat lovers, this one's for you.
05:32Look how the red light disperses through white fur compared to black fur.
05:36By the way, pure white cats are the rarest.
05:41And white cat fur isn't actually white.
05:43It's colorless.
05:45That's why the laser light can play with it like this.
05:48And that's also why white cats and cats with white spots are more likely to get a sunburn.
05:54So keep yours away from the bright sun.
05:57I wonder how long it took for this new and shiny remote to turn into this, well, not so good
06:04looking one.
06:05Ah, this guy needs some good cleaning with wet wipes anyway.
06:09Remotes collect more bacteria than your toilet seat because you touch them more often and hardly ever clean them, right?
06:17I'm getting Alice in Wonderland vibes.
06:20This key looks too small.
06:21And this one is too big compared to the usual one.
06:25But I guess different sized doors open with different sized keys.
06:31If you like cooking, I want to say sorry in advance.
06:34This is what pans can look like after 6 years of intensive use without proper cleaning.
06:40I guess a mixture of 1 tablespoon of baking soda and a few drops of dish soap in hot water
06:46could help solve this problem.
06:49You gotta let the pans soak in the mix overnight for maximum effect and then scrub away the debris.
06:57This coffee grinder brush was definitely used for 4 years.
07:01Just compare it to the new one.
07:03Do you clean your coffee grinder regularly?
07:06Remains of coffee and coffee dust build up in there and change the taste of your coffee brew.
07:12And if you use the same grinder for spices, then you'll also feel their taste in your coffee.
07:18But you can easily clean your grinder if you run uncooked rice in it from time to time.
07:23It will collect all the stuff that doesn't belong there and your brush won't look like this.
07:30Do you like Smarties?
07:31Then you'd be happy to find this extra large one in your pack, I guess.
07:37Oh, looks like someone took a photo of my favorite pair of Converse and doll shoes.
07:43Wait, it turns out that these aren't for dolls, but for women.
07:473-inch shoes were a beauty standard in China for a thousand years.
07:52To make their feet slip into specially shaped lotus shoes like these, women had to go through foot binding.
07:58They say this fashion was inspired by a court dancer who lived in the 10th century.
08:04The idea took off and a small foot soon became a sign of a distinguished lady in the country.
08:11Someone must have used this reverse osmosis filter a lot.
08:15And yes, I already googled reverse osmosis for you, and it's a system for removing contaminants from unfiltered water.
08:24Water passes through a membrane, which keeps all the bad stuff from getting into your glass.
08:30I guess it's time to replace this filter.
08:33Flies are everywhere we go, literally.
08:36It's believed that flies originated in Asia, but these days, they live everywhere people live, only excluding Antarctica, and maybe
08:45a couple of islands.
08:47Flies have traveled the oceans following humans, but they never go anywhere alone.
08:53In the wilderness and deserts where humans are absent, you won't find any flies.
08:59We know them well, but we all have that unanswered question about flies.
09:03Why do flies rub their limbs?
09:06Turns out, they just clean them.
09:08It's this simple.
09:09A fly has hair all over its body.
09:12The hairs on the limbs serve as detectors for flying, finding food, and doing whatever else the fly business is.
09:19They have to keep their limbs clean at all times.
09:23So, they just rub them every time they get a chance.
09:27Their limbs are sensitive, and they serve more than one purpose.
09:31Apparently, the limbs have taste receptors, so the flies can taste with their feet.
09:36They can land on their potential meal and wander around it, giving it a good taste before consuming it.
09:42Flies can't chew, so they're on an all-liquid diet and drink their food.
09:47If the food they have picked as their next meal is solid, they have a special ritual to make it
09:53edible.
09:53A fly regurgitates digestive juices on their soon-to-be food, and those juices break it into the smallest pieces
10:01that can be drunk.
10:02Also, spitting out those juices frees up space in their stomachs for new food.
10:08Quite often, flies sit on our food.
10:11They can appear harmless, but it's not exactly true.
10:14First, remember that they spill out those juices onto your food, which is already gross enough.
10:19But there's more.
10:21You have to keep in mind that flies land everywhere, and it's not always flowers, but all the gross stuff
10:27as well.
10:27And flies especially like that said gross stuff, like rotting foods, dumpsters, and even worse.
10:35So, their limbs collect all the germs and microbes from those places.
10:40When a fly lands on your food, it transfers those germs to your meal.
10:45Some of the microbes they transfer can even cause diseases like cholera and typhoid.
10:51There was even an experiment once made to demonstrate how it works.
10:55There were two bowls. One contained a red powder of some kind of spice, and the other bowl had white
11:01rice in it.
11:02Flies were let in, and they would migrate from the spice bowl to the rice bowl and back.
11:07Soon enough, rice got covered with red spice.
11:10Now, replace harmless spice with something grosser, and rice with your dinner.
11:17So, you should always cover your food to make sure some fly doesn't take a walk on it and step
11:22and spit all over it.
11:24If you're eating, make sure you swat them away.
11:27But don't worry if some annoying fly manages to sit on your sandwich for a second before you kick it
11:32out.
11:32No need to throw the sandwich out. If you act it fast, then you're safe.
11:37Also, experts say that an average healthy human has a strong enough immune system to repel parasites.
11:44Even though flies are gross and annoying, bugging around and tickling you with their limbs, they do serve some good.
11:51They're responsible for pollinating flowers.
11:54They collect nectar from them, which gets stuck to their hair on their bodies.
11:58And then, they pollinate the next flower when landing on it.
12:02Also, if flies didn't exist, our planet would be even dirtier.
12:06Flies recycle some of the human waste.
12:09Flies are also an important part of the ecosystem, since they're food for birds, spiders, lizards, frogs, and many more.
12:17Without flies, they'd all go extinct.
12:22Apart from flies having the superpower of tasting with their feet, there are other interesting facts about them, too.
12:29They can walk on both horizontal and vertical surfaces, and even upside down.
12:34They can do it because each one of a fly's feet has two pads with tiny hair.
12:39And those hairs produce a glue-like substance that allows flies to have an excellent grip.
12:47Flies have unique eyes, which have a large complex of 3,000 to 6,000 simpler eyes within each of
12:54the two compound eyes.
12:56A fly's eyes don't move, but its vision is nearly 360 degrees.
13:02They can see behind their back.
13:04So, wherever you are, a fly definitely sees you.
13:07And every other danger with one or a few of their thousands of monitors.
13:12In addition to the two compound eyes, flies also have three simple eyes located on their foreheads, which serve as
13:20a compass and allow a fly to navigate.
13:25They also have an amazing reaction time.
13:28Ever wondered why it's so hard to swat a fly?
13:31Well, to a fly, we're sloths.
13:34That's because they see things in slow motion compared to us.
13:39Species have different perceptions of speed.
13:41The speed we see will be twice faster for a turtle, and it will be four times slower for a
13:46fly.
13:47Turn a video on at 0.25 times speed and imagine someone approaching you with this speed.
13:53Well, that's how a fly sees you.
13:56So yes, it has enough time to escape.
13:59A fly has just one set of wings.
14:02But, in addition to their pair of wings, they also have so-called halters, which allow them to take off
14:08fast.
14:09Millions of years ago, halters were serving as a second pair of wings.
14:13Now, they help to take off and also to balance the air.
14:17If a fly loses one of the halters, it'll start flying in circles.
14:21And if both of them go missing, it won't be able to fly anymore at all.
14:27Also, even though their wings beat up to 1,000 times per minute, they're also very slow flyers, only reaching
14:34the speed of 4.5 miles per hour.
14:37If a fly lives in an urban area with enough people and garbage around, it doesn't fly far away from
14:43the place of residence, only having a territory of a bit over 3,200 feet.
14:49Rural flies are far more explorative, and they can fly away up to 7 miles at a time.
14:56A fly doesn't live long.
14:58Its lifetime is just around 30 days.
15:01But during this time, they lay from 500 to 800 eggs each on average.
15:07But it's not 1,000 at once.
15:09It's several goes throughout their life.
15:12With 75 to 100 eggs at once, the eggs hatch within 24 hours.
15:18And it takes a week in total for an egg to turn into a grown fly.
15:22And then the cycle continues.
15:23In colder climates, this process can take twice as long.
15:29A timber fly is the biggest fly species, which lives in Central and South America.
15:35They can grow up to 3.15 inches.
15:38Also, flies have beds or more like their favorite spot to stay and sleep.
15:43They have a comfy place, somewhere close to their source of food, and they come there to rest at night.
15:50If you ever had your house flooded with flies, here are a few tips for you to reduce their population.
15:58First, it's important to understand what they're attracted to.
16:01They're attracted to other flies, and even to the smell of flies living there.
16:06And flies have an amazing sense of smell.
16:09So, if you hosted even one fly, expect to get more guests.
16:14If you have any traces of flies, like fly specks, they'll find you too.
16:19Make sure to wash your walls and surfaces.
16:23Next, flies love garbage and rotting produce.
16:27They lay eggs in rotten food and meat.
16:29So, make sure to keep your food in the fridge, cover it, and keep the trash in tightly sealed containers.
16:36And, of course, take out the trash regularly.
16:38Flies have a sweet tooth, or more like a sweet foot, since they taste with their feet.
16:43And, they love syrup and other sugary liquids.
16:47They're also fond of soda and vinegar.
16:50So, make sure to keep those stored, and always wipe after yourself if you spill something.
16:55Lastly, they like to hide and live in dirty and leaky drains.
16:59They eat the bacteria from there.
17:01So, always clear your drains and repair any leaks right away.
17:05Also, it'll help to seal all the cracks in your floor, ceiling, and walls, if you have any.
17:10That's one of their ways to get into the house.
