Query: Very great prank gift.

It won't trick most people, but if you tell them that it won't hurt, they'll go for it. When I got it, I shocked myself by pulling on it, it doesn't work through cloth, so that's good. But if gives you a nice shock down the arm, but once you get used to it, it doesn't hurt, but kind of feels cool and funny.Wrapper gives it away, and the piece of looking tin-foil sticking out. Would not recommended for the weak-hearted.
