Mesmerising HD Footage Of Coloured Water On The International Space Station

This is really cool: astronauts onboard the International Space Station have long shown off what it’s like to play with water in microgravity. Now, they have taken some ultra high-def footage with colour and effervescent tablets.

Pouring Molten Aluminium Into Different Melons Casts A Bad Arse Hand Grenade

When you mix molten aluminium with a watermelon, you get something truly awesome. So what about other melons? Here the Backyard Scientist tries pouring molten aluminium into honey dew and cantaloupes to see what happens. Cantaloupes don’t really offer much but honey dews capture the liquid metal and turn it into a hand grenade-looking sculpture.

A Sword Made Of Fire Is The Coolest Thing

There are swords that are on fire, swords made in fire and now, swords that are made of fire. The Backyard Scientist created this “fire sabre” which is basically a seltzer bottle that spits out a stream of butane which lights on fire with a lighter. The look of the fire stream resembles a light sabre, hence the fire sabre.

What Happens When You Put A Coin Into A Block Of Dry Ice

Video: Everything starts shaking, and the coin looks like it’s trying to escape the block of dry ice in a fit of fury. The ol’ science experiment is always fun to see because everything reacts so quickly. What’s actually happening is that the coin warms up the dry ice, turning it back from solid carbon dioxide to gas, which furiously moves the coin around.

Venereal Disease And Self-Experimentation Should Not Go Together

Early scientists were not at all shy about experimenting on themselves. Isaac Newton stuck a needle into his own eye socket. Robert Hooke shoved his arm into a vacuum chamber. And in the first episode of Sacrificed from Fusion, we learn what 18th century physician John Hunter thought was an effective way to investigate gonorrhoea and syphilis.

Human Experiments: The Good, The Bad And The Ugly

Research involving human subjects is littered with a history of scandal that often shapes people’s views of the ethics of research. Often the earliest cited case is English physician Edward Jenner’s development of the smallpox vaccine in 1796, where he injected an eight-year-old child with the pus taken from a cowpox infection and then deliberately exposed her to an infected carrier of smallpox.

Female Orgasm Explained With Fifth Grade Science Experiments

Video: Talking about sex doesn’t have to be X-rated — and in some cases, it shouldn’t be. That’s why I love this video from Wired’s Data Attack team, which illustrates facts and statistics about women’s orgasms using classic elementary school experiments. You’ll never look at the egg-in-a-bottle experiment the same way again.

High-Speed Footage Of Levitating Water Drops Looks Like A Fireworks Show

You’ve probably seen those experiments where scientists are able to levitate foam balls, or tiny drops of water, using nothing but ultrasonic sound waves. It’s utterly mesmerising to watch something just float in mid-air, but magnitudes cooler when filmed with a camera recording at 20,000 frames per second.

Make A Simple Electric Toy Train With Magnets, Wire And A Battery

Before you go out and spend hundreds of dollars on a fancy Lionel train set to circle your Christmas tree, here’s a simple but remarkable science experiment that will save you a few bucks and blow Santa’s mind when he stops by on the 24th.

Super-Cooled Nickel Ball Is Even Better Than Red Hot Nickel Ball

The red-hot nickel ball is our all-time favourite destroyer of basically anything on the planet, transforming everything from cheese to Peeps into sticky, bubbling cauldrons of processed-chemical goo. Now the ball is rolling in the other direction with a liquid nitrogen-cooled nickel ball that’s up to all sorts of fun.
