Triangulation by Stephen A Yachanin

A volunteer is asked to mentally choose one of several items and write her choice on the back of a business card. Three other volunteers are seated in the shape of a triangle and are given the opportunity to simultaneously remove items from (and replace items into) the center of the “triangle” and exchange items between themselves until only one item remains. The volunteer’s choice is read from the business card and it matches the remaining item!   Triangulation takes an old, powerful technique into uncharted territory. Simultaneously control the “free” selections of two or three volunteers to create the illusion that their subconscious decisions were guided by the unseen forces of the triangle.
