Honestly this is just stupid. Those spouting the apple from tree and mouldy food items as genious accidental discoveries are missing the point entirely. People before the apple fell had things land on or arround them, people before that mouldy lump of bread no doubt had food stuffs go off. The genious isn't in the accident, it's in the realisation that the accident may mean something.
Now we can fairly certainly say someone, somewhere has done this before but never thought anything of it. That being said is likening the kid messing with the moddle to the apple falling and the teacher thinking it could be something to Newton formulating gravity. So since we don't credit an apple with the discovery of gravity, we shouldn't credit a kid for dicking round with a ball and stick model, the discovery is the teacher's. He presented it as a potential new molecule and thus the analysis was made.
