When I was a kid on a small farm, we burned our trash in an open fire. One day, I found a pint-sized rusty can of insecticide -- probably had DDT in it, still containing some of its contents.
I placed the can in the middle of the fire, and got back a reasonable distance. Several minutes later, it did just what Madbutchers' stove did. Only it blew about 50 feet into the air.
Ah those young and crazy days.
