You all know the free fall ride — the ones at amusement parks where you go up to the top of some tall structure then they essentially drop you off it. You get the sensation of falling without having to jump out of a plane, or the sensation of smashing into the ground.
But do you think you could sink a shot off one? These guys did. (Thanks J.E. Skeets for finding this.) The best part is the first shot, where you fall at the speed of the ball.
