The Penetrating Ring

Magician takes two rubber bands and twists them around each finger of his right hand. An examined nickeled ring is placed on the first joint of the second finger. Attention is called to the fact that it cannot slip down to the base of the finger because the rubber bands prevent it from doing so.

In a moment, however, the ring passes the bands and slides down to the base of the finger. The rubber bands are still around all the fingers and the ring seems to have penetrated them. Then the magician slips the ring off his finger again, apparently right through the rubber bands.
