DIY phone cases, faster charging, saving broken cables – you’ve heard all the most common tips out there. But hidden gold? Roll-up smartphones of the future? And have you ever wondered why all phones look the same today? They are rectangular, they have bigger screens and fewer buttons. But some of us still remember the era of smartphones in all kinds of weird shapes and sizes. The Motorola V70 blew everyone’s mind in 2002 with its 360° rotating keyboard. It looked like a fidget spinner long before those were ever a thing! In 2003, we got the Nokia 7600. This phone was shaped like a teardrop, and the keyboard was placed awkwardly around the screen in the middle. The 2004 Haier P7 Pen Phone was a phone shaped like a pen that, ironically, didn’t work as one. So what happened to all those futuristic concepts?

What happens if you wreck a car on a test-drive? If you’ve ever purchased a car, chances are you took it for a spin first. But what happens if you take one of those turns a bit too sharp, or someone cuts you off at just the wrong time. What happens if an accident occurs during the test-drive? So if an accident occurs during the test drive, will the dealership make you pay for the damages out of pocket? Car dealerships, like most businesses, insure their inventory against damage or theft. Dealerships spend thousands of dollars a year on insurance policies, with the price tag for larger businesses reaching into the millions. So, case closed, right? The insurer covers the cost of repairs, and you go on your merry way? Well, not always.

Actually the whole Dubai was built on the edge of a desert and yet it's home to over 200 skyscrapers. Let's see how skyscrapers are built in deserts and what keeps them stable and strong.

Being part of the royal family isn't all about travel, beautiful outfits, nice food and smiles. There're some pretty strict and sometimes strange etiquette rules and guidelines each of the members must stick to. For example, did you know why the Windsors can't actually give you an autograph? Or when the Queen stands up from the dinner table everyone else also needs to stand up? Let's take a look at all of these reasons why it’s not easy to be a member of the British Royal Family.

Imagine you just wake up one day and there's no electricity, no internet, no money, and no work or school. Nothing you're used to! You're not even in your own home, because you’ve magically transported to the Stone Age. What could possibly happen next? Of course, your first reaction would be shock, but we'll move past that. First, let's look around. This is your cave where you live with your family. You have your own sleeping area that’s covered with animal skin. However, you might also live in a primitive hut supported by mammoth tusks and ribs, with an animal skin over it as protection from the rain. And if you're wondering where the Stone Age people did their business, don't be surprised to find out it was basically anywhere outdoors.

How to save your eyes from smartphone strain? Imagine sitting all day long with your arms held straight in front of you. You can probably stay like this for half an hour or even more, but then your arms will feel like they’re made of rock. Same with your eyes because they’re also operated by muscles. That's why constantly using your smartphone or computer does make you tired. The reason why your eyes get tired of too much screen time is in the short wavelength and high intensity of the blue light. You see the sky as blue on a clear day because it’s the color that scatters most easily of all. The same happens when you’re staring at your smartphone or computer screen: the light scatters in all directions, making it hard for you to focus, and your eyes strain to see a clear picture. So how to prevent tired eyes caused by computer and smartphone screens?

They crawl out from underground and terrify the masses. They create chaos, devour entire villages! Giant worms! Yeah, we've all seen stuff like this in the movies, but that’s not quite how it’d go down in real life. Well, hypothetical real life. Say you’re a farmer in this world. You own fields with rows and rows of vegetables and some fruit trees. Your friends are coming over today, and you’re all going four-wheel riding in the valley near your farm. You’re having a great time and don’t even notice the beautiful blue sky disappear behind dark grey clouds. The valley gets swallowed by a blanket of darkness. Off in the distance, you hear rain falling. Dread filling your eyes. You book it out of there full-speed toward the farm. The rain is heavy now. The Earth starts to shake beneath. A gargantuan worm appears, the size of a jet airplane! It wiggles its way out of the ground and crawls on the wet grass... Here's another scary (or not?) "what if" video. This time, we tried to imagine what life would be like if huge worms lived inside the earth. By the way, if you're looking for cool facts about animals, this video is definitely what you need.

Have you ever thought of what it would be like to lose all your teeth? Let's imagine you’re a famous actor who stars in exciting action and adventure comedies. You have millions of dollars and millions of fans. It’s cool, but you want something more. You want serious roles and acting awards. That’s why you decide to play a character who has lost all of their teeth. And to better prepare for the part, you choose to remove all your own. But how can having no teeth affect your digestion? Well, a smoothie diet can't replace regular food. Your stomach will be struggling to get vitamins and have digestive issues. Dentures help chew, but they put pressure on your gums. Besides, food particles fall behind and underneath the dentures and irritate your entire mouth. The dentures don’t weigh much, but it’s enough to make your mouth feel tight. And the worst thing is you can’t taste the same as before. Your palate also has taste buds, but now it’s blocked by the dentures! Your body is losing energy every day, and your immune system is weakened...

Do you love incredible stories of animals saving human lives? Well, then this one will definitely amaze you. In the fall of 1924, Curtis Welch, the only doctor of the port town of Nome in Alaska, raised the alarm: there was too little of the cure for a sudden illness striking the town. Dr. Welch ordered an additional batch and was hoping to receive it before winter because otherwise the town would be locked out by ice for 8 months. But the ship with the cure didn’t make it in time, and the town had no choice but to wait until spring. There were no signs of an outbreak in Nome, but Dr. Welch was still beside himself for some reason. In December, he took in several patients with a sore throat, and although he ruled out the illness, his suspicions grew with every passing day. Until finally, in January 1925, they turned out to be correct: he officially diagnosed the first case. Nome was home to about 2,000 people, but 10,000 more lived in the surrounding area, all at risk of contracting the illness. Over a million units of the cure were found across the country and shipped to Alaska. But the real challenge was to get them to Nome itself...

If you spend only a day at the gas station, you can see just about everything. The “get every last drop in the tank” types, the nozzle tuggers, the nozzle ripper-offers! And possibly even a few near explosions! So today, we decided to spread the most common mistakes people make while fueling up! For example, do you remember that thing about static electricity igniting invisible fuel vapors? Well, get this: when you get out of the car, your clothes sliding against the seat fabric creates some static charge. And when you grab that metallic nozzle, a spark can happen. That tiny spark can light up those gas vapors!
