Color Blind Deck trick
Stand-Up Comedy Magic That Leaves Them Laughing and Stunned
A spectator is chosen from the audience and handed a laser pointer to use for a "mental experiment." You display a large card with red, green and yellow sections. The spectator points the laser beam at whichever of the three colors they prefer, it's a totally free choice...apparently. You keep moving the card around so it's the color "you" want them to pick. After they catch on you really do offer them a free choice and reveal that your prediction perfectly matches their choice!
Comes complete with printed card, laser pointer and secret gimmicks.
