With this Gem you are able to gain possession of borrowed rings, bills, messages, etc. to be reproduced later in a nest of boxes or any other way. You toss a lit match into the Devil's Cannister and real flames shoot up to fill the whole interior. Now any spectator takes out any bill, notes the serial number, and THEY DROP IT IN THE FIRES, where it is consumed in the flames. You can then remove a sealed envelope from your pocket, tear it open and remove THE SPECTATOR'S ORIGINAL BILL!! Spectators may drop their own rings, coins, etc., into the flames and you have instant possession of them.
