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.┬áNot bad, science nerds.
