Blow myself up, eh?
Hey, Lycanthrope--we're talking big noises, flames, and flying bits of debris here! It's no fun at all unless there is a possibility of being blown up! Well, almost. (I'm thinking of a line from The Mikado : "There is beauty in the bellow of the blast...")
Remember Mom's admonition: It's only funny until someone gets hurt!
And your silent addition as a kid: Yeah--after that, it's hilarious!
Why do you suppose that every year, for the 4th of July, there are more and more restrictions on the types of fireworks allowed, and every year, a few kids of all ages manage to hurt themselves anyhow, and every year, the news media, politicians, and law enforcement go "Tsk, tsk!" about it? Do you think that possibly the media people, politicians, and LEO's enjoyed blowing things up as kids, or not???
