Well, sure, it's funny NOW.

I take pictures because I don't really think people would believe me without evidence. 

As the Hurricane was being marched outside for running in the house and generally being a little shit walking by the fire extinguisher, he yanked on an apron (see: dust-covered lump in Exhibit A, just west of the dusty blue sippy cup) that was hanging from it: both the apron and the fire extinguisher hit the floor.  As it hit the floor, the top assembly popped off the extinguisher and the extinguisher skittered all over the floor (almost like it had contents under pressure or something!). In a matter of seconds, the interior of my house looked like a cage match involving cornstarch and super fine baby powder. Even with all the windows and doors wide open, it took about ten minutes for the dust to settle. Literally.

Since I'm all about sharing, let me pass on my new-found knowledge (thanks to Mike @ Fire Prevention): what's inside an ABC fire extinguisher is pretty much baking soda plus a couple of other chemicals to keep it from clumping up.  It's non-toxic to ingest and harmless to breathe.  It tastes like ass. And now you know.
