CRYSTAL COIN CASE
A coin is securely sealed in full view inside this Magic Crystal Coin Case. However, when covered with a napkin, it can magically escape!

Secret: For this trick you will require the square Crystal Coin Case, a coin and a napkin. The clear plastic sides bow slightly when you push on the edges. This allows the coin to escape.

Seal a coin inside the Crystal Coin Case using the elastic bands, as shown. It now looks impossible for the coin to escape. Ask someone to cover your hands with a napkin. As soon as this is done, squeeze on the sides of the case releasing the coin. Immediately show that the coin has escaped and yet the crystal case is still firmly sealed!
