Here is a good reason to get quality, heavy-bottom brew pots. When you can afford them.
I put my thin aluminum 30 liter tamale steamer on the electric range, poured in 2 gallons of water, and turned the element to high. One minute later it was rocking from left to right and bouncing all over the place. Whoo-yeah I had to put 2 full gallon jugs on the lid to hold it down.
The thin bottom expanded with the heat and bowed outwards, pushing it up. The water cooled the bottom irregularly and it would shrink and settle back to one side or the other. Rinse and repeat.
It stopped bouncing around when the water heated up, but for a while there it looked pretty silly.
