The magician displays what appears to be an ordinary drinking glass coaster. A glass is inverted over a plastic coaster. The magician then vanishes a quarter or smaller coin and instantly the coin appears underneath the inverted glass! Or the magician can do a simple sleight and make the coin apparently penetrate the glass and appear inside. The appearance is visual, instantaneous, and quite startling. Comes with coaster and complete instructions. Any plastic or glass drinking tumbler can be used. 002NUFRO00170
