Not firearms, but a foolish boyhood attempt at making
Twelve year old Concray has a bunch of firecrackers. The bigger ones, big as two fingers.
The ones that are said to take such fingers off if they go off in your hand.
Twelve year old concray, with his mental issues and his hatered and childish curiosity decides to harness that power.
He has a bow, the kind of bow that a child has.
He has arrows, made from plastic and fiberglass with no tip. The kind of arrows a child has.
He also have pop-corkfrom an angeldon (Don't know the english name, but here is a wikipedia article with pictures: http://sv.wikipedia.org/wiki/Angeldon
Basicly, it's a cork with a little gunpowder in it that blows up with a little bang and some smoke when struck.
So the little shit has all these, by themselves harmless things. using a cut open beer-can to wrap three of the firecracker swith the pop-cork to the arrow in a way I won't go furter into, he has, in his own mind, made a weapon. The little asshole is feeling manly as fuck, and goes out to try it. His little sister tags along, because, well, why do little sisters tag along for anything?
Long story short, little Concray shoots the arrow into a tree, there is a bang, the aluminium splinters, and his sister gets a piece the size of a thumb stuck in her throa and starts bleeding profusely.
Parents are ran after, first aid administred, an ambulance is called, a girl survives, and one stupid boy never plays with anything explosive again. He also learns what shame is, and why big brothers are not allowed to be idiots.
Off topic, maybe, but I feel that it was stupid enough.
