Here’s a lovely clip on YouBurp from an old movie. You will see a young John Scarne as the magic trick demonstrator, Mr. Calypso, doing a quick and smooth Cups & Balls routine.
Watch it first, then read on!
Scarne’s cups through cups move, however, is the slowest and thus less deceptive one I have ever seen. And the (unnecessary) cut before the climax really hurts! Also, I’m wondering: Is it really a benefit to lift all three cups to show nothing underneath immediately before the final revelations?
