You take out a Japanese fan to use for a volunteer to hold. Next you ask him of her to be VERY careful with it because it is very valuable. You fan it and as an afterthought hand it over to an assisting spectator to fan likewise. Wonder of wonders! When the assistant opens it the fan breaks into fragment. You take it back, open it and fan. It is perfectly alright. Hand it back to assistant and when he/she opens it, it is again in pieces! The more time you do it the funnier it becomes! This magic trick is very easy to perform!
