Yesterday my class had science, everyone thought science was gonna be the same ol' neucleases and stem cells but they were wrong! We were making instant ice cubes… using nitro. Our teacher told us about some chemicals and what they reacted to, and then warned us about two chemicals that were the same color, those were to be used VERY CARFULLY! Some dumbass used some other chemical or coloring substance in one of the jars that were the same color and another in the other jar. When the teacher told us to put the green chemical on the RIGHT into the cup, the kid had no idea which one was the right cup because he had muddled the around. I saw what the kid was doing and I knew what was gonna happen, I put my hand up and told the teacher I had to got to the toilet. I ran to the toilets and decided while I was there I should just stay put until 5 mins before the bell. I waited about one or two mins until I heard what sounded like and air-raid siren… I ran to the classroom and opened the door. This huge cloude of smoke came out at me and choked me, then I got knocked down by all the people crawling out of the classroom. I looked inside and saw burning table with little burning globs of something.

No one was hurt but we aren't allowed to mix chemicals anymore, we do crappy stuff like make those lil volcanos and make goo, then talk about how it all works.
