April 24 2013 Wringing a Wet Towel in Orbit
Aboard Expedition 35, CHris Hadfield performed an experiment to see what would happen if he attempted to wring out a towel in space. Of course, there is no gravity aboard the space craft so the water does not simply fall to the floor as it would on Earth. Rather, the high surface tension on the towel causes the water to coagulate on the surface and form a sort of bubble around both the towel and Hadfield's hands. The gravity aboard the mission is not actually zero but is very small and is referred to as microgravity. The phenomena which causes the water to stay on the surface of the towel is similar to that which creates raindrops on Earth.
