Flower Pot Fridge!

The world's cheapest and easiest refrigerator to make, it uses minimal resources and runs completely without electricity. It's called a zeer pot, or the pot-in-pot and was rebirthed by Mohammed Bah Abba, who put the laws of thermodynamics to work for mankind.

The zeer pot, is just two simple pots, one pot smaller than the other.
The smaller pot is put inside the bigger pot, and we fill the space between with sand. We wet the sand twice a day and cover the top with a wet towell to keep warm air from entering the interior.

Things You'll Need:
Two clay (terracotta) pots, one larger than the other
Sand
Water
Cloth to cover the pots
Clay, cork or other material to plug holes in the pots

How long will this fridge last before needed to change out sand or add more water?

[TheGreatTamara]

This is amazing! And quite revolutionary in hot parts of the world that don't have access to electricity/can't afford a refrigerator. I love passive technology!

I don't understand why this video has any dislikes... Is there some loser out there thumbs downing random videos?

[Steven Phillips]

It should last about a day or two, depends on the outside temperature. You won't have to change the sand ever, just saturate it with water again once it dries out, the same with the towel.

I can tell that this makes perfect sense. it obeys the 2nd law of thermodynamics by moving the heat required to evaporate the water to the surrounding system
