Magic Tricks

Yeah, you do you have to complete the gimmick yourself which is a bit of a drag, but the DIY is simple and a one time deal- 10 mins tops. The ad says that you end clean- not quite true- you cannot hand the box out at any point though it looks normal from the outside. However, the effect looks great and is utterly inexplicable. You could perhaps do a switch while they examine the coin and bag, which is where the initial heat is on after the effect, if you feel the need to clean up.

All in all, this is a cool effect and can really wow people.
