M80s were great back in the day. Amazing that they'd let an 8-year-old kid walk out of the store with a bag of them... essentially a few sticks of dynamite. A little kid could buy cigs, explosives, and a Playboy... all at the same store. It was a different world. I filled one of my grandmother's soup pots full of water, took it into her back yard, and dropped a lit M80 in it, thinking it would form a geyser of water when it exploded. No, mostly it just split her soup pot open. She was not amused.
