The premise of this trick seems simple enough. The magician tucks a silk handkerchief into a clear vial. Wrapping the tube in a piece of paper, the magician hands the package into a spectator.
Now, whenever the magician chooses, the spectator can unwrap the package to discover that the handkerchief is gone!
This trick can be used to vanish nearly any sort of small item - nearly anything that will fit inside the Crystal Capsule can be easily vanished. Bills, salt, tissues, etc.
