Bombmaking was not on the approved lesson plan

David Pieski, a high school chemistry teacher in Orlando, Florida, was arrested for allegedly teaching his students how to make homebrew explosives. From the Associated Press:

In Pieski's classroom in Orlando, authorities found a book labeled "Demo," which includes the chemical breakdown for a powerful explosive, the arrest report said….

Pieski told investigators he detonated chemicals in a coffee can by a ball field four times for his students, the sheriff's office said. He said he did this as a chemistry project to show a reaction rate…

School officials told investigators that Pieski previously had been told he was not allowed to have any form of explosive on campus.

I certainly would have benefited from Mr. Pieski's guidance in my high school years.
