Wiregrams

Ellusionists.com is the only place I have seen Wiregrams. This product is basically a piece of wire that when you apply heat, it turns into a shape. The same it changes into is a type of card. For instance, a trick you could do is have a spectator choose a card, and have them return the card to the deck. Tell them that you will put the cards away and while you do, have them hold on the wire and concentrate on that card. Explain that the wire is a special mind reading wire, and that as they concentrate the wire will absorb the brain waves, and interpret them. You could even say that if they avoided the card in their mind, than inversely the card would still be found by this wire. When they are done, and you've pattered enough about the wire, take the wire back and pull out a lighter. Apply the flame from the lighter to the wire, and it will start to move on its own. The wire will then resemble the selected card!

Wiregrams are really fun. People literally freak out when they see the wire move all by itself. They can even be the one holding the wire, and you can hand THEM the lighter. You don't need it back, because there is no sleight of hand - you are not manipulating the wire at all. This is a great product, and the price is very low, and you can reuse the wire again and again. This is a great piece of magic to add to your repertoire, I highly recommend them.
