The Chicago Surprise - A Card Routine By Whit Haydn

The magician, through sheer force of will, can cause the ink printed on a card's back or face to dramatically change. A red-backed card is freely selected from a red-backed deck. The back of the chosen card changes color to blue so that it is easily found. The blue-backed card is placed under a saltshaker, the spectator's finger or even under the spectator's foot. Then another red-backed card is freely chosen from the deck. The magician, by merely snapping his fingers, changes the face of the blue-backed card to the face of the second freely-chosen card.
