When I was a kid I once missed an episode of "Trick and Treat with the Magic Hands" show, where a pair of hands in darkness does a trick and then reveals how it's done. I only got to see the ending. There were a few cups/glasses placed upside down on a book/tray. Then he lifts and turns the book upside down and the cups do not fall. There may be handkerchiefs involved, book or the cups might have been covered at some point. I've been wondering about how exactly he did it but can't seem to find anything about the trick. Does anyone know?
