Glemme by Patrick Redford. Inside you’ll read how to make anyone forget almost anything with a reliable method that doesnt rely on pure psychology to make it work. The subect will always feel as if he forget that very something he or she was asked to remember.
Here’s what it looks like: The participant is asked what color his/her shirt is. After responding the performer openly writes this color down so the rest of the audience can see it. The performer then places in participant into the proper mind set and turns the board around to show the subject the word and asks him to "lock it into his memory". The subject responds with an affirmation that he has indeed done so. A few moments go by and the subject can’t remember the written information no matter how hard he tries!
Glemme features all new handlings that allow the effect to be performed on stage with props like a dry erase board, note pad/large scetch pad, playing cards, combination locks, or it even with your very own business cards. An interesting benefit is the performer can "bring back" the forgotten memory at any point having the subject instantly remember what they have supposedly forgotten.
SPECIAL BONUS - A handling that teaches you how to make a specific ungimmicked combination lock open on any combination entered by the audience. They can actually take the lock home with them because the combination they enter really is the combination that the lock is set on!
