Unbelievably from these the performer is able to construct a perfect magic square. All the columns rows diagonals and corners add up to the same number. Not only that but this number was chosen by a spectator just a few moments earlier. No formulas. No memory work. An incredible mind boggling routine for the professional worker. <br />Instructional DVD includes performance footage. Bonus Feature Luis de Matos handling of the Instant Magic Square for impromptu work. <br />Running Time Approximately 44min
