The performer hands five ESP cards, each bearing a different symbol, to a spectator and requests that he remember one. The spectator is then asked to shuffle the cards. The magician takes the cards back and, after an apparently fair mixing procedure, correctly divines the selected symbol without even looking at the faces.
The method uses an old mathematical ploy but it is dressed up differently here.
This effect was featured in the May 2005 issue of Magic Magazine.
