This is just majorly cool: how water acts in outer space, without gravity to dance with.
Imagine you’re an astronaut. You’re orbiting the earth in a space station for weeks on end. At some point, you’re gonna want to wash yourself. Or your fellow astronauts are really gonna want you to wash yourself. How to pull this off?
Obviously, a shower would create a potentially tremendous mess. Plus water is very heavy and therefore fuel-expensive to carry, so you wouldn’t want to waste your limited supply on anything besides precious life support.
Enter the special astronaut washcloth. It looks like a little condensed hockey puck. So you shake the thing out until it looks like a small towel, then get it wet to give yourself what my mother used to call a “spit-bath.”
What happens when you wring the washcloth out in this gravityless environment?
Watch and be amazed.
One more thing that adds to the overall fabulousness of this: the experiment was originally proposed by high school students! Go Canada, supporting the curiosity of your young people.

CSA Astronaut Chris Hadfield performed a simple science experiment designed by grade 10 Lockview High School students Kendra Lemke and Meredith Faulkner. The students from Fall River, Nova Scotia won a national science contest held by the Canadian Space Agency with their experiment on surface tension in space using a wet washcloth.

CSA astronaut Chris Hadfield has made a number of interesting videos showing aspects of everyday life in space. Do check them out, and let yourself fill with wonder – plus perhaps a new appreciation of how gravity makes life so much easier down here.
