Two pieces of board showing a Brick Wall are displayed and then put together to form a solid Wall. The performer explains how magicians could walk through a brick wall. The secret to the trick is actually on the other side of the brick wall. When the performer flips the pieces of cardboard over and they are put back together, there is a square hole visible through the middle of the board. It's a geometric vanish that blows the minds of the audience. Includes patter for corporate presentation on creative thinking. Totally self working and incredibly deceptive!
