10 Chemistry Teacher's Lesson Experiments Which Went Horribly Wrong (VIDEO)

So by now you should have all seen the teacher who set the fire sprinklers off after his experiment got a tad out of hand (if you haven't, watch it).

These incidents are usually rather amusing - unless, of course, someone gets hurt. Then it's not funny. We've trawled YouTube just for you to gather all the amusing non-fatal chemistry experiments in one place.

If you've seen a funnier chemistry-experiment-gone-wrong video, then please do post it on our Facebook wall or tweet it to us @HPUKStudents.
