You won't be surprised by the secret behind this trick. You probably did it back in school when
you're little. It's true, you can do this while you're performing with no other gimmicks other than
a pen and paper. However I prefer doing the prep ahead of time and I think it will still be a strong
trick. 10 seconds prep is all you need! Teaching is clear! The reason for 4 stars is I personally
think that the "move" involved to make this trick work will be a little weird if you do it for as
long as they recommend you to do it while spectators are in front of you. I can't say anything more
without revealing the secret. Overall this is nice trick to do strong mentalism on the fly without
using any of the expensive pads available out there. Buy it if you want to learn something quick and
easy to do but still gets strong reactions from the spectators if presented well!
