A Double-Headed Coin

1) When you slap this coin – head side up – into your left hand.
	2) There’s a head on the other side as well!
But – there isn’t really! Still there’s head showing on each side, so how is it done?
Here's a slow-motion explanation …
3) Right hand moves quickly but smoothly from under coin;
4) Coin starts to drop into left hand:
5) Right hand turns over; coin has nearly reach left hand now;
6) Coin has fallen on left palm, right hand is ready to slap down on it.
— so the coin never really turns over!
