How to do it

1. Hold the coin between your thumb and your pointer finger so that your palm is facing you.
2. Sweep your other hand over the coin and pretend to grab it.
3. But instead of really grabbing it, drop it into your hand that's holding the coin.
4. Then, you rub the fingers of your other hand like you have it.
5. Then, pretend to fling the coin into the air so that it looks like it disappears.
