A small pay envelope is placed on the table. The spectator cuts the cards and FREELY (!) chooses which half will be "used in the experiment." A card is selected from the chosen half (and again- it is a truly FREE choice!) The spectator is then asked to merely THINK of one of four symbols: a triangle, square, star or circle. Finally, the spectator chooses one of five "invisible magic markers" (and again- it is a truly FREE choice!) and is asked to imagine the face of the selected card and "draw the chosen shape in the chosen color on the face of the selection." The performer picks up the tabled pay envelope, removes a single card and hands out the envelope for examination. The card is turned over... it matches the selection and on the face of the card is the chosen symbol drawn in the chosen color!! Very easy and resets in seconds! Includes Bicycle cards, pay envelope and complete instructions!
