Warren Stephens' Thru-Ball

A shot glass is placed on a coaster and covered by a inverted tumbler. A small ball is shown and placed on the bottom of the tumbler. A handkerchief is draped over the ball and glasses. When the handkerchief is removed, the ball is seen resting in the shot glass having penetrated the bottom of the tumbler. Includes instructions and two red plastic balls. Very good condition. A great visual trick, easy to do.
