Invention Idea: Auto-Rotating Pot

Burning flame captured several days ago.

While observing a pot of boiling cream of wheat, I had to keep stirring it to cook it evenly. The pot slowly started spinning on the countertop.

In other words, it tries to maintain constant temperature for each portion of the food.
