When you're cooped up in a small cabin with the same people on a space mission, you'll probably want some fun experiments to keep you entertained.In this 4K NASA YouTube video, astronaut Terry Virts grins widely as he pops an effervescent tablet into a floating ball of water, watching as it dissolves and releases gas in mid-air. Using a syringe to inflate the floating bubble with even more water, Virts looks a bit like a glass blower as he carefully makes his hovering mass of effervescence and water expand to sizes larger than a golf ball.The footage was captured by the RED Epic Dragon camera, which is able to shoot sharp images at up to 300 frames per second. The camera was delivered to the International Space Station in January 2015 via SpaceX's fifth cargo resupply mission, and is being evaluated by crew in space and on Earth."This is a huge leap in camera technology for spaceflight," said Rodney Grubbs, program manager for NASA's Imagery Experts Program at the Marshall Space Flight Center, in a press statement. "These cameras have large sensors capable of very high resolution imaging at high frame rates. It is like having a high speed 35mm motion picture film camera, but it is compact, can use lenses we already have up there, and it is digital. No film to return to Earth."The camera provides a valuable and serious tool for science investigations. However, during the trial run, Virts proves that it's pretty awesome just to play with too.
