I always get a kick out of the ping pong ball bobbing up and down on a column of air from a shop vac. Neat to watch it jump up and down and see who can pin it to the backstop. Also get a kick out of shooting a clay pigeon suspended, swinging on the end of a string. Or the shot taken backwards, while standing on one foot. (Almost had a chance to use that one this last deer season, when a doe snuck up behind me.)
