When he's not taking orbital videos of Earth's auroras, NASA Astronaut Don Pettit is experimenting with water in zero gravity. He's already shown us how water droplets can orbit around knitting needles in a microgravity environment. Now he's playing with water again, this time—antibubbles.
We've seen it before, but India's Wall of Death never ceases to awe and amaze. Below, taken from the Guardian's Eyewitness photo series, a man performs the incredibly dangerous stunt during Jhiri Mela, in India ("a fair held every November in memory of a farmer who killed himself in the face of unjust demands from a landlord").
With this cool little how-to, learn about Newton's laws of motion and try first hand to see centripetal force in action. You'll need balloons and a coin and a lug nut.
Find out how everything in a chemistry lab works, from pipettes to burners to recrystallization to storage. You'll get precise instructions on how to work and perform certain scientific duties in the chem lab, whether it's chemical or just ordinary high school science.
CHOW member Eric Higgins uses whole canned tomatoes to cook. As their seeds spoil the food by giving a bitter taste, he gives us step-by-step instructions to remove them using a salad spinner.
Ken demonstrates how to hit a golf ball far. A golf shot starts with a good grip to give it power and flexibility. Grip the golf club under the heel pad creating a 45 degree angle. When the wrist flexes and hinges, the angle will be 90 degrees which will give you power and speed. This promotes flexibility, control and a desirable centrifugal effect. Create speed through motion. Keep your feet together to keep your body quiet and you will increase the speed of your hands and arms. It will also...
This is a simple process for those wanting to capture a circular view of an object with their smartphone or other type of camera.

Why, for the love of God, do people keep inventing ridiculous devices that make the simplest things more complicated in the name of convenience? This may be a rhetorical question that will forever go unanswered—because these crazy gadgets just keep rolling out, one after the other.
This video shows various experiments with circular motion. In Dr. Carlson's Science theater he uses water, a lit candle, and a piece of paper to show the ways that circular motion causes gravitational pull. The water in a glass doesn't spill as it is spun around 360 degrees in a circle, even upside down. The flame on the candle was pulled toward the center when spun around. The piece of paper becomes a paper saw and was able to cut wood when spun. He not only demonstrates centrifugal force wi...
Want to light the skies with your own flying saucer? Here's a quick way to add lights to an ordinary fribee using a cheap light-up yo-yo. It's so easy, anyone can do it.
If you already have the skills for amateur beekeeping, as outlined in Mary Reilly's previous video, then it's time to start harvesting the honey from those honeybees. Mary shows the fruits of her busy hive and demonstrates honey extraction techniques. Mary and Kelsey Clark suit up in heavy-duty garb to sweep irritated bees from the hive frames. The comb on each frame is then raked to expose the honey. Then the frames are placed in an extractor that spins out the liquid gold using centrifugal ...
Water covers approximately 70 percent of Earth's surface and the human body contains up to 78 percent water, depending on body size. Yet, water seems to be taken for granted here on Earth. But if you travel to an orbital altitude of about 250 miles, water starts looking pretty interesting. Especially to astronaut Don Pettit on-board the International Space Station.
The Wall of Death is an adrenaline-junkie's dream—a gripping, precarious balancing act of motorcycles racing in rapid circles around the interior of a creaky wooden drum. In today's world, the act appears in touring side shows and carnivals across the US, India and Europe. The performances in India are particularly thrilling (mostly due to the seeming lack of safety regulation). But the death-defying New Delhi boys shown above didn't invent this insane tradition. It was created in the old US ...
You've seen his explanation of a combination lock's inner workings. You'll never lose another game of Jenga, thanks to his winning wooden pistol. And nearly 4 million YouTube users have marveled at his wooden marble machine sculpture. He's Matthias Wandel, and he's accomplished what most only dream of—turning a hobby into a career. Matthias has been tinkering in woodworking since he was a child, with unrestricted access to his father's workshop, permitted to use power tools unsupervised from ...
