The Devil's Canister is a multi-purpose prop, especially useful for those performers who don't use assistants. By using it, you can gain possession of borrowed rings, bills, message etc. Here's one possible routine -- Borrow a bill from a spectator and have him sign it. Toss a lit match into the Devil's Canister. Real flames shoot up and fill the whole interior. Drop the bill into the fire, where it is consumed in the flames. Now, reach into your pocket and remove a sealed envelope. Tear it open and, there inside, is the signed bill. Along with the canister, you receive a manuscript of 20 effects you can work with it.
