I Can't Stop Drinking Coffee Out of This Temperature-Regulating Mug

My daily coffee routine goes something like this: I arrive at the office, drop my bag next to my desk, grab my mug, and head to the kitchen. I fill it to the brim with the delicious Stumptown brews WIRED provides and bring it back to my desk. Then begins a careful countdown: I have to wait a few minutes for the joe to cool, then drink it as fast as possible before it gets cold.
