The Magician shows two coins sitting on top of a thin piece of rubber latex. The rubber latex is spread across the top of an elegant wine glass and fastened to the glass with two rubber bands. It is clear that nothing can get into the glass without first removing the rubber latex. The Magician asks the spectator which coin he likes, and removes one of the coins from the top of the glass. He asks the spectator to push on the remaining coin with a finger. When the spectator pushes on the coin, it inexplicably penetrates the rubber latex covering and goes into the wine glass with a resonating clink. Amazingly, there is no hole in the rubber latex and everything is fully examinable. (You provide your own coins.)
