Cannonmn,
I've never seen this kind of explosive fire alarm (really not a bad idea, after all, the house is already on fire) before, but looking at it brought to mind this episode of the PBS series "History Detectives" that I watched recently. I had never heard of this kind of cadaver collecting taking place in America before, either; it kind of brings to mind Edgar Allan Poe, or some of those old British Hammer Studio horror flicks.
BTW, the investigator ends up at the Rock Island Arsenal in Illinois, and you can spot some
ordnance in the backround.
After opening the site, it takes a few seconds for the video to start.
