Hot Cocoa Physics

Just in time for the cold weather, at least here in the upper northern hemisphere, APS Physics Central has a nice little experiment that you can do at home with your friends and family. Using just a regular mug, hot water/milk, cocoa mix, and a spoon, you can do a demo that might elicit a few questions and answers.

For those celebrating Thanksgiving this week, I wish you all a happy and safe celebration.
