Thermodynamics entertainment for the day:

October 30th, 2001

Thermodynamics entertainment for the day:

  1. Start with an empty ceramic mug.
  2. Use the water valve on an espresso machine to fill it with
    about two ounces of boiling water. Swirl for 5-10 seconds. (This is
    ostensibly to flash-clean the inside of the mug.) Empty into sink.

  3. Fill mug with cold water from water cooler.
  4. Hold the mug in both your hands; over the course of about
    20 seconds, the hot ceramic will be palpably overcome with cold.

It’s a unique sensation.
