Slap! by Anton Corradin - Trick1SteveMay 28, 2009I purchased this effect from a store in San Francisco, but never got to see the performance until I bought it and took it out of the box, and read the how to. I was totally shocked that I payed way too much for the gimmick and sadly was out $200 dollars. Just watch the video, and you'll instantly see (what I didn't at the time) how it's done and what you're paying for.
