Definition & Meaning of "hot foil trick"

What is the "hot foil trick"?

The hot foil trick is a magic illusion where the magician impresses an image, word, or design onto a piece of foil using heat or pressure, seemingly without any visible tools or equipment. Often, the magician will have a spectator select a card, name a word, or choose a symbol, and then, with a wave of their hand or a quick touch, the chosen image appears on the foil as if by magic. This trick is often performed using a special gimmick that allows for the transfer of the design onto the foil through hidden means. The effect is visually striking and leaves the audience wondering how the magician managed to create the imprint so quickly and mysteriously.
