OK GO just released the first music video shot entirely in zero gravity. They went to a cosmonaut training school in Russia, and filmed it on a plane that’s used to simulate weightlessness.
The song is “Upside Down and Inside Out”, and the whole video is pretty cool. But it gets crazy about halfway through when they open a bunch of suitcases filled with colored balls that start flying around.
Then they start breaking water balloons filled with some sort of paint.
