Funny. I just found this on amazon for 39.00. It’s a 4 brick maker. It’s next on my list. Look for two pot refrigeration. Two clay pots with sand. Amazing. I think it’s also called zero pot. Youtube has video.

I found the Zero Pot video. I think I'll make one.
When camping we used to keep food in a wet canvas bag to keep it cool - worked on the same principle.
If you see one of these canvas water bags at a yard sale or flea market buy it.
They actually work pretty good to cool down your drinking water.
They were very common before the age of air conditioning.
So cool (pun intended). We bought everything to make a 10" tester fridge at Home Depot, cost under $10.
If the SdoesHTF, I would use this fridge to save any cooked leftovers or fresh/mixed dairy products (maybe store a dozen fresh eggs).

"...Leaving food out too long at room temperature can cause bacteria (such as Staphylococcus aureus, Salmonella Enteritidis, Escherichia coli O157:H7, and Campylobacter) to grow to dangerous levels that can cause illness. Bacteria grow most rapidly in the range of temperatures between **** 40 °F and 140 °F****, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone..." Hijacked from USDA.gov
