What happens when you wring out a wet washcloth in space? Amazing, mind-bending, counterintuitive things -- just check out the video above.
Last week, Hadfield conducted an experiment based on a question from two high school students who wanted to know what would happen if a soaked washcloth were squeezed out while in orbit.
"It's becoming a tube of water," Hadfield says in the video while twisting the washcloth. "The water is all over my hands. In fact, it wrings out of the cloth into my hands."
As Hadfield explains in the video, the surface tension of water causes it to behave in a very curious way in zero-gravity conditions, kind of like "Jell-O."
This isn't the first time the ISS commander has played with water aboard the station. Recently, Hadfield showed what happens if you cry in space. He's also taken some really cool photos, including these shots of Earth from orbit:
