Technicolor Prediction trick Lewis
EFFECT: The performer displays three envelopes - one red, one green, and one yellow. Two spectators, a man, and a woman, are invited to each select an envelope. The choice is fair, but the performer insists he has predicted the spectators actions. We'll assume the man chooses the red, the woman the yellow. Each is asked to open their chosen envelope, remove the papers within, and read out loud the message thereon.
The man reads out "I predict you will choose the red envelope."
The woman reads "I predict you will pick the yellow envelope." Of course, the audience assumes this is burlesque mentalism. However, the performer's green envelope contains a paper reading, "I predict I will be left with the green envelope; the man will choose the red; and the woman will choose the yellow!"
