The magician holds an envelope in his hand and tells his audience that he has a euro banknote inside and that this will serve as his prediction. He announces that this bill is only one among the seven existing possibilities (5, 10, 20, 50, 100, 200 and 500). A spectator freely selects one of these seven denominations. The magician opens the envelope for all to see. Incredibly, inside is the exact bill that the spectator freely selected!!!
