Did you know this could happen?

I'm at work and get a call from home that there was an explosion somewhere in the house. It turns out that a can of shaving cream burst, spraying its contents around the bathroom and propelling itself through a light fixture. I normally use an electric razor, and only use a manual one every few weeks when I'm too lazy and go too many days without shaving for the electric one to handle it. Apparently, over time, the bottom edge of the can rusted to the point that it couldn't contain the pressure and blew out. So lesson learned, keep an eye on old pressurized cans and toss them when they start to rust.

It looks like the contents escaped so rapidly that the pressure in the can dropped to the point that the side caved in.
