Ickle Pickle Nickel

Yes, it happens quicker than the eye can see- and you can do it right away!
This one takes ABSOLUTELY NO SKILL!

Place a nickel on your spectator's hand.
Tap the nickel with the magic disk- instantly and visibly the nickel shrinks to a MINIATURE nickel!

But that's not all!
You can also choose instead to change the nickel to a dime!
Or you can make the nickel just disappear, leaving nothing in your spectator's hand!

And that's why this trick is INCREDIBLE!
If you can tap the disk on the nickel- you can do the trick!
