A card is selected by a spectator. It can be placed in their pocket or returned to the deck. The magician introduces a piece of wire. Passing the wire across a flame causes it to magically bend itself into the shape of the spectator’s selected card!
You can use Fire Wire over and over again. People will often want you to "do it again" so we recommend getting more than one for the times this happens. They'll never be able to figure out how you did it, and it will look like real magic
