Get hypnotized by this wave pendulum … seriously, I can’t look away.
A wave pendulum like this is built of equally weighted objects suspended by different (and carefully calculated) lengths of string. Released simultaneously, their differing periods (frequencies of oscillation) cause them to form a “wave” image together that cycles through all possible patterns.
It’s mind-boggling. Looking for a science fair project? This would be a great one.

From the BBC’s The Secret Life of Ice, an experiment for the DIY files:
Dr Gabrielle Walker and Dr Andrea Sella investigate the molecular make up of ice crystals. They use supercooled water to create a mass of ice crystals instantly and discover why water expands as it freezes into ice.

Ice crystals form on a soap bubble at -30c in Northern Sweden.
Because doing physics in space can produce some rarely-seen results, NASA astronaut Don Pettit conducted experiments on video while aboard the International Space Station in 2011/12. In this Science Off the Sphere video, he pops balloons in microgravity. Space Balloonacy!
So here’s the test — think about what you think will happen in this scenario. Will the water stay exactly where it was pre-pop, or will it move? If you think it will move, why would it move?

Has the kid seen windless kite flying?
Member of Team iQuad and recognized as one of the top Rev pilots in the world, Spencer Watson flew this winning indoor kite competition performance at the 2013 Windless Kite Festival in Long Beach, WA… he is flying an Indoor Rev.
