The Great Square Ball Mystery - Goshman
A sponge cube is shown by the performer and nothing else is concealed in his hands. The cube is placed on top of his left fist and his right index finger pokes the cube out of sight into the left fist. His two hands are separated instantly. He then asks the audience if they can tell which hand the cube is in. It does not make any difference which hand they choose though as when the performer opens up both hands he has a sponge Ball in each hand! The cube has vanished and in its place are now 2 sponge balls! The performer then places the two balls together and once again pokes them down into his left fist. The hand is instantly opened to show that both balls have vanished and in the fist is the cube again! A superb Sponge Ball Mystery!
