Awesome Tips 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

Does this work better, the hotter the weather? Or does a good draught help in cooler weather?
Thank you for demo. Planning to do this in Puerto Rico.,I have been living here 2 years. They told me I needed 18,000. For a transformer. I don’t have the money so this is it going to to to make 2 zeer pots one for veggies and one for fruit. Thank you again.
It was Invented by Mohammed bah abba, from africa.
Does it work only with clay pots? There are other materials I can use as sostitution?
My college didnt allow us to use fridge in the dorm. Sure, we can just illegally plug it in but i rhink this is a clever workaround.
Cool! do you need to add water to the sand in any moment? and do you need to wet the towel just once?
Evaporative cooling does well in dry parts of our nation,
but what about humid sites, such as Nashville?
Anybody here tried doing this with a bigger pot? Would love to know if it will do a better job cooling.
This is amazing !!!!!!!!!!
Would be great if you could include or use Celsius since we're being scientific here.
This link from the fabulous charity Practical Action (formerly known as Intermediate Technolgy) contains more ideas along these lines.

The inner pot has to be glazed or painted to make it waterproof. If you don't waterproof the inner pot it will not work coorectly the water will seep into the inner pot and start to heat up. Believe me I made the same mistake as you.
Will this work in a place which has high humidity?
The science is awesome….would need to scale this up considerably to be useful though. I for one would not want to wait 10-12 hours to cool just 2 beer. I'd never be able to get a drunk on !!!
How great is that you are amazing how do you come up this
naice
Thank you so much
Made on my birthday
Can you use this method to safe your stuff for weeks or even months or is this just made to make it through the day?
I wonder if you could turn this into a evaporation-cooling air conditioning unit.
Good, Does it work inside a car/truck as well ? ~I needed a Chiller for my car and this one looks a perfect thing
But they need to have water
wonder what the temp would be if you added a 3rd pot.
belgie ftw !
im going to use thins in my treehouse
This is very ancient way of having a non-electric fridge! But! My question is how long does these sustainable temps last with a zeer pot similar to this size? Would you be able to store foods in a zeer pot for days at a time??
So if you where to add a third layer inside the second pot, would you get cooler temperatures?
It lasts atleast a day or, however long it takes for the sand to dry up.
Cool, thx
Anything that can hold the sand and a wet towel fits over
Does it work with plastic buckets, too?
Great system! But I do not agree on the beers you want to cool inside. Beign from Belgium 🙂
Will this work indoors? (sorry if it is a stupid question)
yes, but not too long time.
It's good for the day at the beach.
Hi
Can this be used to keep meat chilled?
i live in britain so stuff 10 degrees C it would go into the minus temperatures round where i live haha
I don't understand why this video has any dislikes… Is there some loser out there thumbs downing random videos?
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.
it's brilliant, I never heard of anything like that before. Thanks for the upload.
0:00 HE LOOKS HIGH
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
hes gay?
men you are the coolest gay i' ve ever met
cool hey can you make it one day before and then take it with you at the beach????/?
what if i put dry ice in the pot with some bottles of beer, will it freeze so ice?
As a scientist, I would like to try it 😉 but it's currently 0C degree outside so I'll wait until summer…
My opinion is that the quicker evaporation would cool faster, which is good. However, as someone said it wouldn't last long. Thats why I want to try your idea of the bigger "reservoir" of sand, it could allow for prolonged cooling, which is also good!.
I'm sure we can optimize this to fit (and cool) an entire 6-pack of beer….mmmm… science…
ahh, yes i can see that as being true. so how about a larger outer pot with more sand filling around the inner pot(which would still be this size) and of course a larger covering? also the material should be one that wics more quickly. what do you think?
Larger pots would result in less surface area per volume, so less cooling for the inside.
