Lucky 7 Forcing Dice by Diamond Jim Tyler
Imagine a spectator numbering six envelopes one through six. They are instructed to place a fake bill in five of the envelopes and their own $100 bill into the sixth envelope and to seal them all. They then roll a die and if the number two comes up, then you or they destroy the envelope marked #2 by burning it or shredding it. This procedure is done until one envelope is left. Miraculously, their $100 bill is the lone survivor. They mark the envelopes. They place their bill inside. They roll the dice. They destroy the envelopes one by one if they wish. It seems to good to be true!
These 16 mm 7 LUCKY DICE are a wonderful secret weapon to have in your arsenal for close-up, parlour or stage.
