Hand o' Doom by Bob Farmer - Trick

The Effect: The spectator thinks of a card. Only he knows it's identity. The cards are mixed together face up and face down. Now---in rapid succession---there are three shocking climaxes; *Instantly, all of the cards turn face up--with the exception of the thought of card! It is the only card still face down. *Suddenly the thought of card vanishes and turns into the 'Hand O' Doom!' *The spectator reaches into his pocket and finds among some other cards he placed there previously--the missing thought of card! Entirely mechanical and self working; requires no skill, no memorization, no sleights. No rough, smooth, stripped, waxed, long, or short cards are used. Remember, the card is not picked--it is thought of! You receive the 'Hand O' Doom,' the secret gimmicks, and a manuscript describing everything in excellent detail. Supply your own Bicycle deck.
