This trick is a demonstration of ESP and has a lasting impression on the spectator.  The spectator is involved from beginning to end.  They choose any of the ESP symbols from the cards.  It does not matter which one they choose.  The top is spun on a board full of ESP symbols.  Top spins and moves back and forth and will land on the the identical symbol as chosen by the spectator.  The board, cards and top are made of fine wood. A nice professional look and feel.  Complete with video instructions.
