Chemistry Evacuation
“In high school chemistry, we were mixing organic compounds in the lab. Teacher’s instructions were to mix one compound, then dispose of it before starting the next one, and under no circumstances were we to mix them together. Well, a couple of troublemakers mixed all of them and it started spewing some really noxious fumes. It was the first time in my school’s history that the chem lab had to be evacuated.”
