You've got your facts wrong

Oxygen by itself is not flammable.If you mix it with something that is burning it will act as an accelerant but it won't burn by itself.

Besides that you've got a great spiel here especially with the Lego dudes.I would have liked to see them animated though.That would have made this flash a keeper.You must have worked awhile on the script as the vo was pretty good if a bit quiet sometimes.

As for the oxygen not burning, trust me.I work with shit like this all the time.

borderline protect

It is quite interesting stuff, I do like lego and it was mildly funny. The sound was very poor at first but got much better.

However, it wasn't really flash animation, in fact it was barely what you could call animation at all, mor eof a slideshow. As such its more youtube. It could do with submtitles and a few pics of oxygen atoms, molecules and its place in the P table.

Not Bad

I didn't realy mind the echo at all. I don't know how much the kids on newgrounds will enjoy learning, but you also had som funny points to cover up the educational parts.

I liked how you had a button to skip the boring parts, but it didn't work. The audio from the earlier part was still playibg even though I skipped head. You need to fix that.

?

What the hell is wrong with you? Try adding some decent sound man! That echo was driving me nuts! I couldn't understand a single fucking word they were saying. I know you allready noted this in your comments, but without sound, this movie is just boring. And it gives me the impression that it's just about some kid playing with his Lego.
Try again. Or, I don't know, add subtitles.
