What Stpid Thing Have You Done Today?

[Alex]

I wonder what my mom's secret was. When I was a kid the standard school field trip lunch included a can of soda that had been frozen (intentionally) and then served to keep the lunch cool and was mostly melted by the time lunch rolled around.

Don't recall the cans ever exploding though often the top would be distended. Wonder if can design has changed since, making them more likely to explode.
