Educational
Even mildly interesting, though I don't think chemistry is one of Newgrounds' favorite subjects. I found it somewhat enlightening ^_^ a sign of intelligence, which is rare, and even a little refreshing. However, friend, I suggest you only submit fun, recreational things to newgrounds. I do not doubt the quality of your flash; I simply doubt its entertaining properties (or lack thereof). Though I found it entertaining--somewhat--not everybody is me.
Good luck in the future!
Happy flashing ^_^
