Astronauts on the International Space Station get to do the coolest experiments. And sometimes the simplest ones can be the most impressive.

Canadian astronaut Chris Hadfield demonstrates what happens when you wring out a soaking wet washcloth in zero gravity. The idea came from two high school students in Nova Scotia who won a contest to design a simple science experiment to be conducted on the ISS. The experiment had to use materials that were already available on the space station and was selected out of almost 100 entries.

Watch the video above to see the incredible effect of weightlessness on the water absorbed by the washcloth.
