I had one of those pump misting spray bottles. I used it to mist my bread dough to get a nice crust. It exploded in my hands while pumping it to pressurize it. It didn't just crack or split. It exploded, embedded into the ceiling, sliced right thru my palm and out the side (six stitches). After inspecting the others (it was a three pack) I realized there was no pop-off or over-pressure relief designed into it, so I threw the rest away in the trash. Lesson learned, but I'm not going to sue anybody.
Water under the right conditions is 1,100% more volatile in expansion than ignited gasoline.
I don't know when I stopped using my brain?
