if you're free falling in one position, without touching anything, with no

spin, is it possible to wiggle in such a way that you're able to rotate to a

different angular position and then stop? On Smarter Every Day we demonstrated this

with a high speed camera and a cat, who is a non holonomic system and can do this

by extending his legs, arching his back and twisting in a very specific pattern.

So can humans do this on orbit? You want to say hey to the astronauts? - Hey.

- Thank you. We look up to you guys.
