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.


Twitter Tests Turning Favourites Into Retweets, Frustration Ensues

Social media websites are one massive, ongoing experiment. If they’re not specifically experimenting on you, then they’re tinkering with function or nipping and tucking design elements to give their site a one up on the competition.


Man Loses 17kg By Eating Exclusively At McDonald's For 90 Days

A man lost 17kg, and his cholesterol level dropped from 249 to 170, by eating exclusively at McDonald’s for 90 days. He ate everything: from Big Macs to salads to sundaes to shakes to quarter pounders. It’s the antithesis of Supersize Me, the pseudo-documentary of a man who did the same — with two crucial differences.


Man-Made Volcanic Lightning Has Been Created For The First Time

The coolest kid science fair projects were always those erupting baking soda and vinegar volcanoes. Nothing captures the imagination like a good ol’ explosion. This is kind of like that but a lot more insane and groundbreaking: scientists have created artificial volcano lightning in a lab for the very first time.


Make A Smoke Waterfall Using Sticky Notes And Fire

Here’s an awesome experiment you can try if you’re looking for a last minute way to decorate your cubicle or house for Halloween. It’s particularly great if you have one of those tiny relaxing waterfalls at your disposal, since replacing the water with cascading smoke is sure to have everyone thinking you’re some kind of wizard — despite your costume.


Deep Space Exploration Trials Sure Look Boring

In order to prepare for the human exploration of the furthest reaches of our solar system, space agencies often run experiments to see how our bodies can cope with long periods of sedentary behaviour. And, my, it looks boring.
