zeer pot

i read about zeer pots a few months ago. it is 2 pots. one pot inside the other with sand and water in between. the water evaporates and cools the inside pot. you can put food inside and it acts like a refrigerator. they only work where the humidity is less than 20%.

our fridge went out on thursday. it didn't get fixed until monday. it was horrible. it's hard to realize how dependant we are on modern conveniences until they are gone. we have a mini-fridge but it only holds a few things. we had to throw out everything from the freezer. even food that didn't necessarily go bad because it all stank like rotting meat. gross.

if the small zeer pot we made today works out, we are going to put together a big one and use it, along with the mini-fridge instead of a regular refrigerator.

here is the pdf from the guy that invented it.

and an article from Science in Africa.

the set up (plus our sage and basil plants in the blue pots on the end)

sifting sand

we plugged up the holes with modeling clay.

pour sand in the bottom until the top of the small pot is level with the top of the big pot.

pour sand down the sides.

noah wanted to help.

fill it up with water.
