Coin under watch

[ipjur]

Hey guys!
So I'm kinda new to magic,I'm learning many new tricks...
Recently I saw a video of a guy (don't remember his name right now) borrowing a coin,asking the spectator to sign it,then he blows into his hand and the coin disappears,only to appear under the spectators watch.
Can someone tell me how to do it please? Not signed coin version is good too. I saw that you can buy like a DVD,but my parents won't let me buy it.

I understand your problem, but this is not a forum for revealing magic tricks - the only thing we can do is giving
sources to learn more about this effect - but that's it...

If you seriously want to learn (and perform) this trick I recommend checking out the Coin under watch DVD by Oz Pearlman. It is also available as a instant download - hope this helps...
