A normal rubberband is examined - then secured on your finger.
The rubberband is ungimmicked - and can even be borrowed. The rubberband is doubled over again and again, securing it in a manner that is clear and fair. With no strange moves, you begin waving your hand gently. As you wave, the rubberband visibly JUMPS to your second finger.
It continues to JUMP from one finger to another - to another.
It finally travels back across your fingers to where it started. The rubberband is slowly massaged with two fingers of your opposite hand. When your hand is pulled away, the rubberband VANISHES - only to emerge in a surprise, shocking finale on the THUMB of your other hand.
