Science off the Sphere: Space Soundwaves II- Electric Didgeridoo

International Space Station Expedition 31 astronaut Don Pettit uses the station's vacuum cleaner and a shirt to make an electric Didgeridoo to test the behavior of non-newtonian fluids in the weightless environment aboard the station. Through a partnership between NASA and the American Physical Society you can participate in Pettit's physics challenge and view future experiments here: http://www.physicscentral.com/sots
