"I have a '05 Black Boxster with 18" wheels, upgraded stereo, windstop and Metallic Paint. Here's my question: How does a Thermos know whether to keep hot things hot and cold things cold?"
Assuming you truly give a crap- a link below. More complex that I would have thought (not that I actually read it - when an explanation loses my interest after a paragraph, I refer to it as "complex".)

Incidentally, did you know that the 987 glove box is "cooled". So instead of using a thermos to keep your Slurpee slurpable you could just pour it into your glove-box directly.
