Pentro Pena Coin
An empty glass is shown with an opaque sheet of rubber stretched over the top and fastened with a rubber band. On top of the glass, two coins rest. The spectator selects a coin and without any false moves, you push the coin through the rubber sheet. The spectator watches in disbelief as it penetrates the rubber and falls with a loud clink into the glass below! Immediately, you hand everything out for examination. There are no holes in the rubber and no gimmicks or extra coins. You are left clean as a whistle. Based upon a clever priciple, you'll be able to perform this trick just minutes after reading the instructions. Use your own glass and rubber band. Works with any coins!
