You ask a spectator to name any card in the deck. She tells you which card she has chosen. You remove a deck of cards from its box and fan the cards. There is one card face up in the deck -it is the spectator's freely named card! Now, for the ‘second’ climax. You prove that you knew the card to be selected in advance by showing that spectator's card has a different colored back than the remainder of the deck! This is a Pro Brand deck that was handmade into a Brainwave deck.
