7 Color Telepathy Card Set. The spectators can turn over one card, then conceal all the cards in the envelopes and mix them so even they don't know where their color choice is located. The performer can tell immediately. A real fooler that can be repeated, and all items can be thoroughly examined.Telepathy Cards are based on a diabolical principle credited to Bob Fillman and Tan Hock Chuan. Briefly: 7 ungaffed envelopes are shown, each with an ordinary card inside. Each is a different color. A spectator selects any card, then turns it over and puts it back into the envelope. All the envelopes are closed, then thoroughly mixed. After the mixing, no one - the spectators or the performer - knows which envelope contains the selected card.

The performer deals the envelopes into a row on a table and has a spectator select one...it is the correct symbol! Instead of having the spectator locate the envelope, the performer can hold each one to his forehead one at a time to get a mental impression, then set aside one envelope - the one containing the selection!

Note: The envelopes are identical and are not marked in any way. The performer cannot see into the envelopes and does not get any clue from any visual clue from the envelopes. Each card is identical in size, shape and color, only the symbols are different. I've demonstrated this effect hundreds of times and often would tell my audiences that the envelopes are ordinary...they come from an office supply store. The cards are cut from ordinary poster board. "If you pay me the replacement costs, you can have them!"

The method is so subtle and fool-proof, that it is the perfect principle for many routines, from standard magic effects to mentalism. The props can be thoroughly examined. Effects can be repeated. Even if a spectator tries to mess things up, you always know the correct answer! For example, if a spectator turns over multiple cards, you'll know.

Since the 1990s, Chazpro has offered several variations of this popular principle. The most popular has been the sets of Blank Telepathy Cards and ESP Telepathy Cards. With these special cards, the performer can customize effects to a wide range of audiences and themes. These cards are perfect for trade show routines, mentalism and spirit effects, Bank Night tricks and more.
