Cork Stopper

The magician wraps a cork with a bill, and fixes it using a rubber band. The bill is rolled up like a tube, and the space inside is divided by the cork into the upper space and the lower space. The magician puts four coins into the upper space of the tube. The coins, one by one, are dropped to the table, penetrating the cork. For the last coin, the magician puts it into his pocket, but it appears from the tube. Everything is examinable after the effect.
