NASA astronaut Don Pettit plays with water in his spare time aboard the International Space Station (ISS).
If you were in zero gravity, how would you while away the hours? Astronaut Don Pettit is seen here playing with something that we barely even think about on Earth: simple H2O. His enthusiasm and sense of wonder for the reactions of the substance when the force of gravity no longer applies is infectious, as he pokes it, blows air into it through a syringe and even creates another "bubble" within his sphere.
"When we go into a frontier, our normal Earth-honed intuitions no longer apply," he says in the video below. "And that's why frontiers are rich in discovery."
So, why is he doing it? "Just because I'm in space, and I can," he said. That's the best reasoning we've ever heard.
When he was done, he collected the water in his syringe and made a cup of tea.
We'd like to go to space, now, please.
