So it doesn't explode because the contents overheat, just like Dimitri
explained. A can by its nature is a sealed container--i.e., it will
become a pressure cooker.

Surrounding it with water that _cannot_, under normal pressure, ever
exceed the boiling point at that pressure alleviates that concern.

Of course, there are some people who wish to demonstrate evolution in
action....
