The Impossible Skateboard Flip

This flip is obviously not impossible, because world class Australian skater Jackson Pilz did it before your eyes, but it is a move that skaters call "the Impossible." Physics Girl collaborated with skater Rodney Mullen, who is credited with creating the Impossible, to make a video that addresses the physics of the trick. The Impossible flip is shown at five minutes in, but the background leading up to it is interesting, too.
