Hey! I'm so glad I spent the five dollars on this -- well, well worth it. The central idea is
incredibly simple, but I never would've thought of it for sure. Using UNO cards, which I guess you
could do it with others, just adds another fun element to this idea.
I can't give away
anything here, but once you know the method, it is easily made even more amazing by doing it in
reverse with the cards turned over. I hope this doesn't violate the rules to say that, but I think
it's an excellent feature of this trick that you can very easily customize it.
