Three coins vanish from the magician`s hand and reappear in a clear glass.  Everyone can see and hear each coin as it arrives, even when the glass is held in the spectator's hand.
Take a box of matches from your pocket and rest it on the palm of your hand. Explain, "This is a very strange box of matches." As you speak the matchbox flips over on your hand! "They look like ordinary matches, but they're not." Now the drawer slowly slides open by itself! At this point your audience is really impressed, but you're not finished yet...

Say the magic word "Viagra" and a 2 inch tall match jumps out and stands on top of the box! Wow!

The improved gimmick is entirely self contained with no body hookups.
