Ahh you're talking about fire crackers, aka bangers! Alright that makes more sense, yes those might be thrown around and they're not really dangerous. I remember buying a ton of them as a kid while on a trip to France, and then busying myself for the next month blowing up my old model planes. They are a type of firework of course, and they might be loud, but that's not what OP's article is about - it's about display fireworks, rockets. Throwing those around and letting them off in the street is a whole nother ball game.
