This is a great little gaff that is good to perform at parties, or even at school. As a magic trick
alone, it isn't very effective, but if you perform it as a gag, then you will get better reactions.
It's pretty obvious afterwards what is going on, so I'd say that if you perform it, don't do it
right before a coin routine otherwise it might make it look suspicious. If you are looking for a
good coin magic trick, this one isn't it, but if you're looking for a laugh, grab trick.
