I actually just purchased this booklet a few days ago, because I saw a similar effect on TV and I was really impressed. I did a little research beforehand, so I understood the material that it contained might seem disappointing or dumb, and most people would add it to their drawer of unused items. Peoples comments conveyed to me that it was indeed a great trick, and that those who actually tried it achieved great results.
As I was anxiously reading the first page, I saw a quote from Richard Osterlind: " Most people will read the effect, not put any thought into it, or time, and never perform it, which is fine by me."
This is okay because the effect will remain exclusive for the performers who are ready.
Although I had prepared myself beforehand, when I learned the method I was still surprised. I decided to be bold and try it. The actual 'trick' is very easy, its mostly the presentation that you need to work on (like most tricks). But you can't really practice without spectators..
So I went ahead and tried it on my parents. I was surprised and happy that it worked, my dad swore I touched him, and my mom swore I only touched her.. but somehow he felt it.
I tried it again the next day at school, with 4 people. Again I achieved success. 3 witnesses said I didn't touch the guy, but he was sure he felt the touches. Everyone saw that I touched the person standing far away. Interestingly enough, a guy passing by who stopped to watch was also a magician. He was baffled as well, since he only knew a method using IT.
So far, so good. I'm hoping to add it into my show soon.
