When I was in high school, I particularly enjoyed the math, chem, and physics classes. I therefore, tried to take an active part. I volunteered to set up a chlorine generator for chemistry class. It was fairly simple, sitting on a table and having an exhaust fan take it away. But the gas was so pale that it was hard to see. So I experimented with making is stronger... and ran out of reagents. One of my buddy's father was a chem professor at Case and Jim had access... I used the Case reagents at the same quantities that I used the high school supplies without pretesting. When I ran the generator during class, they emptied the wing of the school. Oh well...
