Bill Tube - Coin&Money Magic

This effect is easy to perform! A spectator signs a bill and places it under a black cloth. The spectator is also given a brass tube sealed with a lock. The performer then takes the black cloth away to reveal that the signed bill has vanished! The spectator is given a key and unlocks the tube. Inside, is the spectator's signed bill!   Includes special cloth and simple to learn illustrated directions!   If you know how a bill tube works, think again, our gimmick is INVISIBLE to the eye!
