This is a great magic that involves two people. It requires a bit of practice beforehand, but you will always be wowed by this secret trick. You will convince any audience of your and your partner’s psychic powers, and they will never guess the secret, no matter how many times you do it. One cool thing about this trick is that you can do it over and over again.

This is how the gimmick will look to your stunned audience. You explain that your friend has the gift of reading your mind, but he or she can only read your mind. Naturally, they’ll ask for a demo, and you’ll produce a normal pack of cards. Let anyone look at the cards to make sure it’s not a deck of tricks, then ask their partner to leave the room or area for a couple of minutes.

The crowd, or the person you are doing this trick with, choose any card. You don’t even touch the cover. They choose the card, show it to you, and then place it where no one can see it. Your partner comes back, sits right behind you, and gently places his fingers on your temples, as if he’s doing the old Vulcan mind meld trick. After a few moments, your friend or partner guesses the card.

Here’s the trick. When they place their hands or fingers on your temple, you gently clench your jaw several times according to a preset code between you and your partner. Try it now if you want, touch your temple while clenching your jaw muscle and you will feel it. One way to do this is to fire a certain number of times to indicate the suit, pause, and then fire multiple times to indicate the card itself.

It may also help if you can lower your head slightly and are able to hold your entire palms against the side of your face. That will have a more dramatic effect and cover any obvious triggers. Also, you’ll need to explain why your partner needs to touch you only in that spot for it to work, so you’ll need to come up with a good story. You can explain to him that your partner is part Vulcan or something.

Of course, this is not limited to card tricks. If you and your partner learn Morse code, you can pass on all sorts of information to each other and entertain your friends for hours. A great example is blindfolding your partner and then having people in the audience hold up simple things, and then you broadcast them using Morse code. If he or she is blindfolded, they will focus more on the integrity of the blindfold than any method of transmission. There are many other ways you can think of to use this versatile trick. Have fun.
