Die-tective is a quality variation of a classic beginner pocket trick. This version has been designed to not only look like a professional item, but to work extremely well. A brass box, lid and die are examined. A spectator places the die in the box any way he or she chooses, remembers the number on top, then covers it with the lid. The performers turns around and picks up the box, commenting on the impossibility of seeing through brass. The box is placed in the spectator's hand, then the performer concentrates, and names the number selected by the spectator. Also included are alternate presentations and a set of six different colored beads for a color detection routine.
