Its a bomb. Drano BOMB. Inside city limits, at school.
If you're going to do stupid things for fun, have the good common sense not to get caught.
The whole point of "nobody gets hurt" means that its easier to get away with it. So you almost have to go out of your way to just stand around looking guilty. Somebody needs to teach these kids how to get away with stuff.
I've set these off before and they can really knock you on your ass if you aren't paying attention (or don't have someone else holding your beer, nyuk)... Think taped sparkler bomb.
A large party balloon sized draino bomb is easily a deadly device.
I suppose I should've said credit cards enable these people to piss their money away faster.
I personally never learned much self discipline. My only recourse at this time is to avoid the things that I'm not strict enough to stay out of trouble with.
