If you want to see something cool watch what happens while wringing out water on the International Space Station (ISS) from a NASA Wet Towel. CSA Astronaut Chris Hadfield performs the simple science experiment designed by Lockview High School students Kendra Lemke and Meredith Faulkner. I like how he shows the towel starting off as a compressed hockey puck sized object and ends with the amazing effect of gravity on the water that is wrung from the wet towel. Very Cool. If you like this you might also enjoy watching International Space Station Space Oddity.
