the third one was a little fast , correct it put it upto maybe 3 to 4 secs

Idk good I guess

Ah lab protocol. You covered the big one, that you always wear protective gear when handling chemicals. You also covered eating in the lab, which is a big no-no. However, there are a couple that you're missing. The big one that I noticed right away was that you're missing procedures in the event of the chemicals splashing onto your skin and eyes. That's a big one. Another one would probably be following the directions given to you, since I imagine that you are still schooling.

For a quick project, it's not bad. I would recommend slowing the time between the text and the animation, in order to give people more time to read. A preloader would be nice as well. Good luck with your schooling.

Obviously sloppy, but the timing wasn't bad. sfx were pretty okay, too.

This would be fine for a simple school project, but honestly, i wouldn't post this to Newgrounds.
