Penetrating coin

This is a nice trick for someone who starts with magic, but it does also excellent for (semi) professional!

The magician has laid a piece of rubber over a glass. In the rubber is a coin.
Then the magician pressed the coin straight through the rubber. The coin falls into the glass.

The rubber should now be a hole, but no ... it's all very, everything is investigating.

Easy to carry out, a maximum effect!
