Double Identity, from the mind's of Michel Huot and Stephan Therien
Effect: The magician asks two volunteer's to each select a card from a deck, asking them to hold their respective card's but not to look at them for the moment. You now call attention to an attractive dog-tag you are wearing since the beginning of the experience saying that people wear them to identify to something. You ask the first spectator what he sees behind on the dog-tag. 'The five of club' he replies. You then ask the same question to the second spectator but he replies: 'the three of spades!' You then ask both spectators to look at their respective cards and they both match what they saw.
Important point; no switching of any kind you only use one dog-tag, no fumbling of any kind, it's straight and direct, pure magic.
