EFFECT: A spectator selects four cards from a deck of playing cards. The performer shows two small plastic chips with “?” marks printed on their four sides. He gently rubs the chips keeping one on the other and the “?” marks magically changes to pictures of four different playing cards (AS, QH, KC and 10D) on the four sides of the chips. All those match exactly with the spectator’s selected four cards.
We supply you the two round chips and instructions . YOU USE YOUR OWN DECK OF CARDS.
