If they say it's not microwaveable,
...turns out, they mean it.
This bowl was round.
This has been a public service announcement by the Explosives-and-Microwaves Committee.
It won't blow up your microwave.
But it will turn a round bowl triangular and smash it up against the plastic cover you placed over it in a kind of melted-plastic kiss of death.
If only I'd gotten a picture of that.
Thank you.
