... Duplicating a design that rests on a flashcard that your spectator hasn't even looked at yet!
... Three spectators removing single or multiple symbols from a stack of cards and you being able to name, describe or even draw each one with our back turned!
... The spectator's producing a chaotic mess of symbols mixed beyond recognition and yet you are able to forecast the outcome!
Symbology is all this and more! A must have item if you are into mental magic.
