The magician attempts to vanish a small silk. With his hands otherwise empty, he pushes the silk into his fist. When the fist is opened, the silk has vanished completely.
The performer removes the silk from his pocket, where it has magically traveled. He attempts to repeat the effect for the benefit of those not watching too closely. Once again the silk is poked into the fist, a magic pass made, and the fist opened. Something seems to have gone wrong!
The silk is still there. Performer looks baffled, then opens out the silk to find it has transformed into a cute pair of panties. The effect is not offensive. While not suitable for all audiences, it brings a good laugh with a more mature audience.
