10. Thermite will burn water, too

meaning you can't put it out with a hose.

I was fortunate enough to run into one marvelous lunatic of a teacher in high school. We did the thermite reaction on school grounds and cooked the infield.

The groundskeeper was not impressed. Most of the class was hooked on science by stuff like that and even happy to do all the math behind it.

...It is also on the nation's exposed bridges and unpainted steel buildings and numerous other structures as a testimonial to the tremendous cost savings of long standing republican efforts at tax cuts and opposition to on-going maintenance of public investments. Rust is the by-product of those policies and should be collected and deposited into their bank accounts since these conservative imbeciles value it so much!
