This happened at the hospital I currently work at a couple years ago. A patient was brought some chicken noodle soup hot in the thermos but didn't open it. A few days later I was working night shift on that floor when we all heard a sound resembling a cross between a BOOM and a BANG (something you don't expect at 2AM). There was his thermos at the bedside table with no lid, still sitting upright. Scattered around (both floor and ceiling) was some fermented soup smelling of fermenting vomitus. And a lid-sized-and-shaped hole in the ceiling.
