When Shin Lim wanted to impress Larry King and Rachel Ray he chose to do THIS. Not sure how you'd even follow it up. It's a 2-phase miracle.
Two cards are selected and SIGNED and torn in half. You then fuze one signed-piece to another creating a brand new impossible object. Here's the crazy part THEY GET TO KEEP IT!
Unlike other "fuzion" or "waltz" tricks that have come before, each spectator gets to keep their own impossible card, EACH ONE SHOWS HALF OF BOTH SIGNATURES.
Nothing is palmed, no difficult moves, the gimmicks do all the work for you.
Here's the catch: Each gimmick is hand-made and it takes a LONG time, which means this isn't a cheap trick. You're looking at about $8 per performance, it's a small price to pay for a world-class miracle.
