The lethal quarter is the adaptation by Geno Munari. Geno realized that the average person doesn't carry around a U.S. Half Dollar (.50 Cent piece), but everyone has a quarter in their pocket and makes the trick more believable. When performing Lethal Quarter, the number one response I get from the spectator is "Do that again."
The effect is so amazing they can't believe what has happened.
I hope you will enjoy reading the various ways I've come up with for presenting the 'World's Fastest Trick" Lethal Quarter. So don't blink don't look away or you just might miss the trick!
