A friend sent me this and now it's bugging me. How didi he do it? I figured out most of Brundage's tricks on America's Got Talent, but this is different (I think). PM me if you know what's going on!
He is using a fake cube, after doing a few moves, all of the sides are solved except for the red one. He only shows this side to the camera. After throwing the cube in the air, he then only shows all of the other sides, you can never see the solved red side.
Edit: Oh, just realized, I overread the last sentence.
