Walter Zaney Blaney performs a wonderful illusion with “The Blaney Anti-Gravity Board” on The Tonight Show with Johnny Carson in 1973. He was assisted on stage by Johnny’s own secretary, a cute young lady named Irene Kay. Walter’s version of this magic illusion is one that fooled magicians longer than any other in the history of magic, for over 21 years, until he showed David Copperfield how to perform it in 1986.
