Harry Anderson performed this amazing card trick on TV!
Fan out six playing cards, show the front and back, and let the spectator secretly mentally choose one of the cards. Fold the cards together, then fan them again. Five of the cards are normal but the spectator's card is now blank! On both sides!! And the spectator never told you which card he chose!!!
No force necessary, no sleight of hand required. Incredible, absolutely astounding- and very easy to do. Best of all, it's ready to go again instantly.
Cards are Poker size, with Bicycle backs.
