Effect:
A spectator is requested by the performer to merely think of a playing card. As this spectator fulfills this request, the mentalist picks up a piece of white artboard and attempts to mentally receive and record this spectator’s thought of selection Directing his attention to another spectator, the performer again request that this person think of a card. As done before, the performer secretly writes down what he feels this spectator is concentrating upon. At the conclusion, after both spectators have revealed their selections, the performer displays what he has written and, to the astonishment of the audience, the mentalist is seen to have correctly perceived the thoughts of both as- sisting spectators.
