Funny to see people complain about knee-jerk reactions with a massive knee jerk of their own.
Chemistry kits and lasers aren't outlawed, so neither of the things are true. Why was this modded up?
Certain chemicals aren't commonly included in chemistry kits marketed for children for liability reasons. Make of that what you will, but that is still a long ways from "outlawed". In fact, I'd guess that most of the things that you might have found in those kids are still easy enough to find. They just don't come in a tin case with fancy graphics.
