After seeing references to this book multiple times over the years, I felt it necessary to finally get it and read it. I like it a lot.

The basic routine is that someone onstage feels definite taps on their shoulder even though the performer is across the stage.

This book is a lesson in psychology, control of how spectators think, as well as a great effect. I know others have put out their own variations of this effect, but it is amazing that all of it started with this simple, 10 page booklet.

Get it. Read it. Try it out.
