I'm standing in the kitchen, chopping some vegetables for a mirepoix. Just assembling a simple chicken dinner. Slicing up broccoli stems, which I'm using instead of celery, when...
The light fixture smashes on the floor without warning! Having a chefly presence of mind, I manage not to slice off my thumb when I startle.
The threading on the rod showed some wear. Could be that this was from regular changing of the light bulbs. Or, the threaded socket might've not had a tight grip on the rod and expanded due to heat. That would explain the noise of the fixture heating up; it was the rod slipping down a thread at a time!
The glass dome fell straight down, so the rod failed cleanly. I know it went straight since it impacted the floor with the metal finial at the bottom of the rod. It left a clean half-inch wide and eighth-inch deep crater in my linoleum, just two feet from where I was standing. Wow.
