Warren Stephens has created this penetration of a solid through a solid, using an empty shot glass which is covered with an inverted plastic tumbler. A bright colored ball is placed atop the tumbler (as in the illustration) and everything is covered with a handkerchief. The palm of the hand is placed on the covered ball and a rubbing motion is made. Suddenly, the handkerchief is removed and the ball is seen to be sitting in the inner shot glass-having penetrated through the base of the tumbler! Only one ball is used and there are no sleights involved.
