Sponge Ding Dong by Goshman - Trick

Warning! X-Rated magic ahead! Only sold to people 18 years or older. The magician displays two sponge balls at his fingertips. One of the balls is held onto by the magician and the other is placed in a spectator's hand. The magician snaps his fingers and opens his hand to show the ball has completely vanished! When the spectator opens their hand, they have two balls. Both balls are placed back into the spectator's hand and the magician again makes his ball vanish. When the spectator opens their hand, now they have three balls! The magician offers to try it again one last time. The three balls are placed into the spectator's hand who closes it into a fist. This time the magician asks, "How many balls do you think are in your hand?" No matter what their answer is, they couldn't possibly guess what they're holding onto when they open their hand: the magic ding dong! Includes ding dong and four sponge balls.
