Astronaut Plays With Floating Balls In Space

In space, no one can hear you scream, but they can hear you go “Ooohh” and “Aahhh”. As sci-fi blog io9 explains, the purpose of this fluid dynamics demonstration is not merely to visually impress and amaze, but also to test out the chops of a new type of 4k camera made by RED. Irrespective of why NASA is dabbling in this kind of magic though, the imagery of balls of water in a zero-gravity environment is totally captivating. Throw in some antacid tablets and some food coloring, and it turns out you’ve got some crazy dancing neon balls from outer space. Not bad, science nerds.
