Starz, your Pyrex story reminded me of the day I dropped a Correlleware plate (which I thought was unbreakable). I dropped it on the hard wooden living room floor probably four months ago and to this day I still find tiny shards of broken plastic (or whatever those plates are made of) around the room. It shattered completely.

The only thing I believe is unbreakable is soft plastic. I have managed to break many items that were deemed "indestructible". HA!
