A trick that fooled Bruce from his friend Dave Bartlett
Did you know that when you go to the eye doctor, he has a set of five eye charts? Why? He has five so you don't memorize the chart! Well you've discovered that with these charts, you can also check out a spectator's minds eye.
A spectator thinks of any letter of the alphabet. Show the spectator your five eye charts and you are able to announce what letter they thought of! You don't even have to look at the charts. You could be blindfolded.
You get five different eye charts and Bruce Kalver's complete instructions. A big hit at all of Bruce Kalver's lectures.
