Just been watching good ole' Derren again, and saw him "guess" how many fingers a spec was holding up in his/her pocket. He got it right every time, and nobody is that lucky
I know in Paul Brook's upcoming manuscript it describes how this is done, but as it is not availbale yut, I am wondering whether or not there is any other source that...well...sources how this is done?
cheers guys in advance!
