Alpha Mental – $12.95

The magician asks a volunteer to merely think of any letter of the alphabet.  There are no restrictions, the volunteer can think of any letter. Next the magician hands the volunteer seven specially printed plastic cards each with a random number of letters printed on them. The volunteer is asked to look at each card and retain every card that has his thought of letter printed on it and discard the rest. Although the magician never sees the cards which the volunteer kept, the magician can instantly name the thought of letter!

Comes complete with special cards, a wallet to keep them in, and of course the secret instructions.
