I started doing Out of this World about 65 years ago when my father's friend taught it to me. It is
one of the tricks that get the most amazed reactions from spectators. I've seen variations over the
years, some of which were very clever, others not so good. The original Curry version (along Harry
Lorayne's Out of this Universe)remained my 2 favorites.
Cosmos Duo adds elements that, I
believe, make it even better than the original, and on a par with Out of this Universe
This was
one of my best purchases from Penguin.
