When I was a boy scout ( a long time ago) someone tried to heat a can of beany weenies in the fire. In the infinite wisdom of a 13 year old they didn’t crack the lid. One explosion and a rain of beanie weenies later we were all ok. At another camp someone threw a can of mosquito spray in the fire. It took a while but it exploded with some fury and blew a hole in the shelter we had setup. We were stupid.
I am just glad that we didn’t end up with the results of this British teen’s mistake. Looks like an expensive mistake.
