The thing is, they're not real life consequences. They're totally artificial consequences, established by the school without adequate rational basis. You could do this basically anywhere but a school, and nothing would happen to you (think fireworks). And there's no serious safety issue here (e.g.: what are the chances this happens again, regardless of the punishment?). It's not at all about safety; it's about the establishment of authority. How Kafkaesque is that? "We made these rules just so that we can punish you if you don't follow them!"
