It's getting hotter every day and your electricity bills are not environmentally friendly.
This credit crunching fridge is a sure way to be sure your beverages will stay chilled in the hottest of heats. It's much greener than your average electrical fridge and will work anywhere where there isn't a lot of humidity.
The pot in pot refrigerator or Zeer was made by Professor Mohammed Bah Abba, though there's evidence it was in use in early Egypt. It works on the principle of evaporative cooling.
You will need:
Two terracotta pots. One has to fit inside the other with an inch or so between all the way round.
A towel/cloth big enough to go over it
5-10 minutes, maximum!
Step 1: First pot
Add about 1-2" of sand into the bottom of the big pot. Don't worry too much about the holes at the bottom, the sand packs down and forms a plug.
Firm down the sand before putting your second pot in.
