Magic Demo of the Spiked Coin

This is a well known trick that is often found in magic sets and kids often buy and perform. In the trick, you place a coin or solid plastic disk into a cylindrical box and place a cap on it, and then seemingly push a series of nails through the box and coin.

This is an excellent trick for kids because it's visual and easy to learn and perform. The only downside is that there are lots of parts and once the parts are lost, the trick becomes useless.

By the way, the "nails" are plastic and not sharp.
