The classics of magic are always good. This is a novel approach to something like a chop cup. It can be done in such an impromptu way it is great! It comes with everything you need, but I prefer to use a couple gimmicked coins in addition to what it comes with so they are more examinable. It also works really well if you are with a group having a bottle of wine and you "borrow" the ordinary cork. You switch out the regular cork with the gimmicked cork and it is a lot of fun!
