Joe Barry - Rainman

In this incredible demonstration of memory, Joe begins with two sealed decks, one red and one blue. The spectators open the decks and shuffle them fairly. He then attempts to memorise one of the decks in seconds before asking a spectator to name a number from 1 to 52. Somehow, he knows exactly what card is in that position! Finally, in a surprising twist, when the spectator is promised that she will somehow always pick the same card, she manages to do one better. She somehow changes a prediction card into her second selection!
