The Dynamite Game

Wolfie has invented a new game, or maybe he found it with one of the silly programs he watches at lunchtime. You tell me if you heard about it before. So anyway, he uses a piece of Duplo (that Lego blocks toy range for younger children) and throws it, saying: "It's dynamite! Run away!" or some such thing and then we must all get away as far as possible from the piece of Duplo, then it goes "Boom!" (well, I say boom, or he says it). I must say, it is quite fun. And it is very simple to play, with minimal props necessary.
