Astronaut shows what happens when you wring out washcloth in zero-gravity (video)
Canadian Astronaut Chris Hadfield performed a simple science experiment designed by two tenth-grade 10 students from Nova Scotia.
The two wanted to know what would happen to water when it is wrung out of a wet washcloth in zero-gravity. Hadfield demonstrated for them from the International Space Station. (Love how his microphone just floats in front of him.)
