You introduce a brass key and a coin. You then tell your audience that you will give them $100 if they can push the coin through the hole in the key. After the audience tries and realizes it’s impossible, the magician offers to show them how.
"CROMO is highly recommended! Very clever! Excellent thinking and topnotch work! It is great to take the work of the greats and advance it. That is how you keep the audience watching the classics "one more time." Thanks for sharing with me! Really impressive work!"
