If you have ever wanted to perform a 'coin in which hand' type of effect, 'Gerti' is for you. You have two coins; you ask a spectator to sign one of the coins. You invite the spectator to place one coin in your hand and one other coin in their own hand. Without looking you are able to reveal which of you has the signed coin. You can also tell which hand holds which dated coin. The gimmick is undetectable and makes for some amazing routines. Routines explained: Lie Detection - You have two coins of the same denomination, one signed by the spectator. You turn around and the spectator keeps one coin and places the other in your hand. You then reveal who has the signed coin. Dates -- You have three coins of the same denomination. The spectator mixes the coins and then places one coin in your left hand, one in your right hand, and keeps the third coin them self. You then reveal what is the date of the coin in your left, your right hand and, finally, the spectator's hand. Numbers - Similar to the 'dates' routine, but you number the coins and reveal who has which numbered coin. With the gimmicked coin supplied all of the above, and more, is possible. The only limit is your imagination. You get: A DVD with full explanations and a custom, gimmicked coin.
