International Space Station Commander Chris Hadfield is renowned for his communication of science. He plays guitar from space, throws up incredible images of Earth from the ISS, and he’ll answer all your curiosities about living in a gravity-free world on YouTube. This recent demonstration was a result of a question from 2 high school students, Kendra Lemke and Meredith Faulkner, who were interested in what might happen when you wring out water from a washcloth in space.
The result is pretty amazing. I was worried the water would short-circuit the electronics, but thanks to surface tension, all is well. I like how a seemingly simple task on Earth becomes fascinating when it happens in Space.
