Didn't anyone of you read the word Repeat? Nobody has been able to do it the way I described. Not Daniel Madison, not Derren Brown.
No he can't. Not 100% surefire. Just quessing.
Derren Brown could probably do it because he is a brilliant magician, but he hasn't published any surefire methods. Just some very good ones that sadly aren't repeateble or very direct. Any mentalist could do it, you say? Give me a break.
Here is an solution use a confederate if they can act well enough it would fool us magicians...on video or live for that matter. May I draw your attention to madison and gianni or am delving into the realms of magic for us magicians.
