This video shows Astronaut and Horrible Narrator Don Pettit playing with floating orbs of water in the International Space Station. He blasts them with air, sticks bubbles of air inside them, then fills them with bubbles of water and sticks an Alka Seltzer tab inside to see what happens. It's all in the name of science, of course, but it's also just really damned cool. [Neatorama]
