A few weeks ago, the internet was wowed by a video of a whiteboard marker stick figure doodle that appeared to magically come to life with a little water. Many assumed there were some unseen shenanigans that made the stick figure leap off the table, but as Steve Mould explains, it's all due to the simple science of erasable markers.

Video: If you ever wanted to be a wizard, or just to try your hand at some magic tricks, you should learn the dark art of... static electricity. Yep, with a bit of strategic contact with certain objects, you can easily fool kids and probably even trick your drunk friend into thinking you can control objects through invisible forces.
Video: We're going to assume that Dan Clinch is a teacher who's either found a great way to get his students excited about chemistry, or is just looking to get fired with a comfortable severance package. Because having them pass around what appears to be an invisible flaming bubble of propane looks both amazing and dangerous at the same time.
Video: Gallium is one of those rare metals that turns to a liquid somewhere above room temperature, allowing you to do fun experiments — like pouring it onto a vibrating speaker while playing music — without risking severe burns. Point a camera at the results and that fun science experiment suddenly feels like you've discovered a distant alien world bubbling to life out of the fabric of the cosmos.
Video: After demonstrating the miraculous protective capabilities of Line-X spray on a watermelon, YouTube's How Ridiculous wondered what else the wonder material could protect from a 45m drop. Surprisingly, eggs, one of Mother Nature's most fragile creations, simply bounced off the pavement after the plunge.
Video: It's called the Schlieren effect and it means that you can see things that are invisible to the human eye, like changes in air density. So when you turn on a hair dryer, you can see the blast of air it shoots out. When you open a can of Coke, you can see what's escaping into the air. When you rub your hands, you can see the heat surrounding them.
Video: Throw dry ice in everything just to see what happens, if you ask me. Crazy Russian Hacker put dry ice in some green slime and a bunch of bubbles started forming out of nowhere. The bubbles eventually pop in a small explosion of smoke but when they first appear underneath that muck of green goo, it's like seeing eggs spawn or something.
