hot foil trick A minor conjuring trick, not commonly used, in which a scrap of aluminum foil is crumpled and placed in the spectator's hand, then the performer suggests that it will become very hot. It does, since a chemical (often a dangerously poisonous mercuric salt) has been surreptitiously rubbed onto it to induce rapid oxidation of the metal, an exothermic reaction producing much heat in a very short time.
The trick is not in the repertoire of any reputable conjuror but has been used by psychics.
