Check out OK Go's new video for Upside Down & Inside Out. The band shot it on a a parabolic flight with the help of S7 Airlines, a Russian carrier. A parabolic flight is where the plane goes up and down—during the up portion of the flights, gravity is roughly 1.8 times normal, and during the " down" flights, it's as near to zero gravity as we can get without being in space. It's what astronauts and cosmonauts have used for zero gravity training for decades. And now OK Go has used it to make a fun, colorful video. Progress! There's also a behind-the-scenes-video with information about the eight takes it took to get it right.
