What do they put in thermometers these days? Is it chocolate?

This post reminds me that I currently gauge the temperature using a two-pound bag of chocolates which melted because we forgot to put it in the refrigerator. Since it had already melted, we didn't bother to put it in the refrigerator -- now it regularly melts and then solidifies over the course of the day.

The bag is so big that temperature changes don't affect it immediately, so I can poke at it and have a rough idea of how hot (or not) it was an hour ago. I've gotten into the habit of checking it after waking up and as soon as I get home. The days have gradually become cooler: the chocolate is more sludgy now, less liquid, when I check on it at the end of the day.

One of these days I shall choose a day with an appropriate temperature (I cannot decide whether hot or cool is best), open up the bag and set mode=devour.
