A spectator populates a row of a 4x4 square with any four numbers. You fill out the remaining 12 squares in seconds to construct a magic square. Does not require any math.

The performer immediately extracts the cube root of this number without the use of electronics, stooges, or gimmicks. The calculation is performed immediately and entirely in the performer's mind, thanks to the secret master key.

This feat, performed on paper after a lengthy effort by a spectator, is considered quite an accomplishment, but performed instantly, it is a sensation. Performer knows only the number submitted by the spectator, and immediately...
