Many magicians have performed penetration illusions because of their strong impact on audiences. It's particularly baffling when the solid objects involved are everyday ordinary items. "Miracle Coin Thru" allows you to perform a stunning penetration effect with an ordinary cup and coin, and without the need for any difficult technique. Your audience will be able to see the coin as it instantly penetrates through the bottom of the cup!

Use your own cup and coins.
