The Brass Falle is a small puzzle in which you can place a coin. Then you just need to know how to get it open first. If successful, a coin can be inserted. If you then give it to someone else to open, can they see the coin but not take it out, or do they manage it anyway? This is really one of those brainteasers that is easy to take with you and still amaze everyone.
