Houdini Scotch and Soda
Magically switch a coin in your hand to a new one that the spectators have never seen, and make the old coin appear in your pocket. This model uses a special Houdini silver coin and a mexican 20 cent piece.
A coin trick precision made from a special Houdini Coin and a Mexican 20 centavo piece. You put both coins into the spectators hand, in full view. The gold coin disappears and can turn into a "MAGICIANS'S COIN".
Can be freely examined at end of the trick. It is entirely mechanical and easy to do.
