Houdini Hanky

Take a tumbler and a little hanky. Pour some water into the tumbler and pour it back into the jug. Dry the tumbler with the hanky and put inside. Cover the tumbler with a large cloth and get someone to hold the large cloth around the top of it. The hanky is now trapped in the crystal castle, but being a Houdini Hanky it is able to escape. As quick as you can blink, Houdini has escaped. The assistants hands have not left the glass. This needs a bit of handling but not hard to do. Comes with everything, except the water and the jug.
