These WORK! I had to keep medicine cool but I was moving off grid to a homestead. One of these zere pot’s kept my medicine 35-40 degrees cooler than the ambient air.
You can use a glazed pot for the interior chamber. The moisture from the sand evaporates through the exterior shell, but still pulls heat (exchange) from the interior sealed pot. It's actually the best choice to have a glazed/sealed interior smaller pot, because then you can use salt water, waste water. If the interior pot is porous, then you must use potable water.
Yes, that's obvious when you think about it. (I hadn't thought about it.) There is absolutely no benefit in having a porous inner pot, as no evaporative cooling happens there. The evaporative cooling happens in the wet towel on top, and from the sides of the outer pot.
How would it work if you had sealed aluminum metal pot on inside? The sand and outer pot do all the evaporating and heat extracting, the aluminum pot would do all the receiving of the heat draw.
Of all the zeer fridge vids I've watched, yours is the best! This 'survivalist' concept could also be a true life saver for ppl who live in high risk weather regions...it could be used for meds that require refrigeration when power is out. In addition, it's more practical than a styrofoam container bc no ice is needed. Believe me when I say that ice became a commodity when we got hit by several hurricanes in just one season. There wasn't enough for those of us who didn't have backup systems like generators... & ended up spending a lot of money to keep those coolers working. Thx for sharing!
Most of the meds people are on, are not necessary. People who currently lead believe they need that stuff, really should take the time to learn about other options. But, yeah there are a lot of people who will drop dead due to that. Many wouldn’t have had to had they not been so pharma indoctrinated and looked for other options. It’s just sad really, because the info is suppressed and if you ask the people selling pharma products and allopathic methods, they will deny other possibilities because they are highly indoctrinated and believe the lies they are told. It may be way too late now, in 2021.
Hi. Read the one above Kalpesh. ( 5 up) I didn't hear of it either. Other guy said use glazed pot for inside pot . Otherwise porous. Just thought the one is interesting.
We have this in our village. 5 times the size of this. We use drip irrigation techniques. Raised pot and a tube that goes around the sand area an inch above to keep the sand / soil moist. The pipes have many more holes than required. We just have to fill that pot 2 or 3 times a day depending on seasons.
This is an excellent technique. The first time I lived in the Phoenix area, my apartment had what was locally known as a swamp cooler - or an evaporative cooler. Worked very well, except during monsoon season, when it was way more humid. Still, far lower utility bills - and you can still open the windows. Thanks!
Inner pot can be glazed so as not to allow any contaminants to enter. Salt water evaporates at a higher level and as the water evaporates the salt content goes up so the pot will stop cooling at a point. Fresh water is better. Terracotta or clay must be used because it is porous and the water can evaporate through it.
Wow this was really great. Thanks for sharing your knowledge about this. In a SHTF situation even if you were to hunt well, not being able to preserve meat in a no-electricity situation would lessen your chances of survival. Chilled meat or vegetables at 40 degrees would last a lot longer than 70 degrees or more. I heard that the Egyptians also manufactured batteries made of copper, clay and fruit juice to generate electricity to plate silver and gold to bronze or other less valuable metals. Maybe we can power some low voltage light bulbs with that ancient technology. Thanks for sharing!
That temperature difference is outstanding! I'm on the sticky and humid east coast. Sometimes during the summer we're blessed with a dewpoint below 65F, but although those days are rare, we usually have some sort of breeze. I will try this! Semper fi!
If you can’t find the smaller terracotta pot with an interior glaze, melt some beeswax, & brush it on. I did this myself a few years ago, & it does work well. It made a good beer fridge! Thanks for sharing!
nice to finally know the name of these things I've been building them for years I've learned in my most southern part of California desert most effective is to use a cloth duffle bag military bags work great with a container inside rather than terracotta pots also you can use cloth such as clothing blanket sheet ect. as insulation substitute of the sand for example wrapping a t-shirt around your water bottle wet it and hang it in the shade of a tree has the same effect
@@juneweimar3383 It would work fine as long as good Tupper ware was use Finding stuff in a duffle can be a hassle but different shaped container helps . Mr Cody has a good method for those on the go.
Greetings from India. Like the way you point out the plus side and caution about the wrong side of doing things. Thanks Corporal. see you in the next. Regards...
Another way to cool and at no cost.. If you have a stream nearby put items to be cooled directly into water at edge, in the shade.. For things that might get waterlogged you need a box to put them in.. Make a platform of stones that come just above the water.. Place a flat stone on top.. Food goes onto flat stone and cover with an upturned bucket, box or clay pot.. I've made jello both ways..
thinking about this for a sec, the interior pot could be a cheap aluminum or stainless pail with no hole in the bottom. Windy location, highest outer surface area, auto-drip, strong shade above and around, and an insulated top might help too.
Good video. And it's easy to follow. I might suggest a watering can for flowers that has a small spout to add water because they usually go fairly slow and would be easier to hold. Great job!
If you arent moving around a lot, say a long term camp or general off grid living, nothing beats a set of crossley icyballs for cooling. Those badboys get cold enough to make ice and will be covered on frost seconds after being set up. Also they work in any environment type. Only need to be heated once a day in a fire, easy enough to work into your morning coffee routine.
Great video.... the same process happens with the wool covered canteens you see in westerns... wet the wool, evaporation cools the water in the canteen. It would have been helpful to use a thermometer to guage the outside temp with the inside temp of the pot for demonstration purposes... Not complaining, only trying to help.... keep the vids coming.
interesting demonstration of the use of evaporation for cooling and a practical application for food preservation. You do very practical videos and are an excellent teacher and challenger
Great Video! Thank you! I live in a desert climate and wondered how to keep food longer should fridge go out and I not have a deep freezer. Thank you for using the thermometer to show the temperature difference. Thanks again.
They Egyptians didn't have slaves, they were compensated! And it's called Ancient Kemet. It was nice and balmy at that time. They had agriculture off of the Nile. Nice video though. Thanks for telling where you got this from. Your very nice for that.
"And white Americans never had slaves either, they were compensated as well". Thats what someone will say 500 to 1000 years from now. As a matter of fact some people already deny that Jews were slaughtered in the millions during the Holocaust. And there is videos and pictures as well as survivors. The moral of the story is you dont know for a fact if Egyptians compensated anyone or if in fact they did have slaves. Its like saying the big bang theory and evolution are facts. When in fact they are only theory.
Bitch, Egyptians were not black. Aside from one short period where Nubia conquered a weakened Egypt for one dynasty and they were a minority occupying force.
As a gardener I stand my tomato plant pots in a tray and water them from the bottom that way it doesn't disturb the top soil I wonder if by standing the outer pot in a tray and filling that with water the sand would soak enough up to keep it wet?
Hell yea!!! Now that was impressive and that's saying a lot coming from me because I am hard to impress. You won my respect so I'm a new subscriber. Keep them coming.
I live in southern Florida, we high humidity mostly moist air but high temps, I'm gonna give it a try and see what I can come up with , seems like a good viable way of cooling things down some.
+Corporals Corner, have you tried any self regulating watering systems to go with this? I am thinking maybe sitting the whole thing in a shallow pan of water so the clay pots draw it up the side walls, just an idea anyway. Great job with this video.
I think the temperature of the inner pot was probably even cooler than the thermometer showed. I thought he would lift a corner of the top cloth to point the thermometer inside, but instead removed the cloth completely and it was probably a good 5-10 seconds the cloth was totally off before taking the temperature. Some of the cool air would have definitely escaped, or warmer air get in. Nice video!!
I am quite shocked at the temperature difference. ingenious idea. i also recently came across a documentary on ancient Persian cooling methods, which are Yakhchāl ice house shelters (stil in use in some areas), they use evaportive cooling as well.
how long does it take for the inside to get down enough and does it stay that cool as long as there is a breeze and wet sand? would be a great thing to take on the beach to keep water bottles cool for my kids
Have read some of the others comments many have shared similar thoughts as i had like metal inner container for better conduction currents, fill bowl shape lid with water and wet cloth ,use or add kitty litter,crushed lava rock,or other porous material to the contents of the outter pot so as to have more space to retain water, (sand looses much of its water retaining ability when compacted)possibly add a small piece of soaker hose with some type of IV drip ,2 liter coke bottle, etc. Convection currents fan,wind help no doubt but what if you could create a natural thermal updraft using solar energy to create a convection current around your Zeer pot aiding the evaporation process eliminating the need for a fan or wind. Sort of a solar powered rocket stove. Just a few of my thoughts
What if you had a sprinkler system set up that kept the outside of your whole house damp in hot weather? Would that obviate the need for air conditioning?
Hi Man, greets from germany! Very interesting video, never heard from this system. As the temperatures here also raises, and our dumb politics has risen the costs of electricity (complete unneccessary: 17 atomcraft powerplants were shut off!) this is not alone interesting for poor people that can't afford anymore electricity, but for all who wants to save costs! But I would take much much bigger pots, with floors between, and quadratic. Maybe in in 1m size, like a small wardrobe. Also the application of the persian ventilation principle could be interesting in combination. Air conditioning engineers certainly know what I'm talking about. Thanks for the inspiration!
Zeer room would be nice and save electricity for AC. -edit- I googled what bricks are made off, turns out it's made from mainly CLAY, which probably helps a bit for cooling the inside of a room. Amazing.
Well, now that it is June 14, 2022 and I accidently came across this and as you know this year is hard for everyone. I will keep this in mind if need to live off the grid. Thank You great idea.
I'm gonna be out in the desert for a week and will be trying this method of refrigeration. About how many times do you think i should be refilling the water inside the pot? Whenever the sand is dry I gotta refill it again correct?
Fabio Gallo if there is 3 layer of insulation like first one is where water sits second on where black clay sits and the third where all vegetables sits. When the clay never go dry as the water slowly pure in to clay.and bet you it will be preserve vegetables for more days.
You could tie the pots together through the holes in the bottom so that it doesn't rise right? Use a bolt with domed head enter from the bottom use metal then silicon washers against the pot on either side and then tighten with a nut
Can I do it in a bigger size? A square or rectangular shape container? Or make one under my cabin ground? Also, is it supposed to be a sand and not soil?
I have been intrigued with the Zeer pots and watching a few videos. Thanks for yours and how you took the time to test them. I have a question: Is it necessary to have two clay pots? I am wondering if it would be possible to use a 5 gallon plastic bucket for the interior pot. It seems that if it is an evaporative principle that it should still work. Is there any reason why the interior bucket needs to be porous?
I want to modify this to make a bird bath in Phoenix. If I were to Cover the two pots and sand with a towel and then exchange the lid for a concave, but shallow bowl and fill it with water… Do you think that would work?
The ancient egyptians used this technology to also make Ice. Back in the 80's I won a $50 bet with a history prof. I used this technique to make him an Iced Gin and Tonic (using Tanqueray Gin) Expensive for a young college kid)... The Hotter the day, the better it works!
Can one use the clay base to cover the inner pot (where perishable is stored). if a glass lid (like the one you used) isn't available? How long does this remain cool? Thank you.
from what I've read/heard, the inner pot should be sealed (no drain hole) and have a vitreous glazing that will keep the moisture out of the interior pot. The out pot should be unglazed, and could even have small holes to aid the evaporation process.
I have a question. I have one of those big huge plastic water barrels, that I’ve been afraid to use because of the ratio of bleach, etc. I now live in a desert. I’m wondering if I could take that barrel surround it with these rounded decorative paving bricks that I have creating a blank space donut in between the brick and the barrel lining it with plastic tarp filling it with sand and covering it as this demonstration describes with a concave lid, to keep drinking water cooler and therefore less likely to grow baddies. Comments?
Great video. Would florida be too humid? I read that people are using this process to actually keep their insulin cool in places without electric. Insane. Again Great video!
Hi Corporal. Can you combine sand & pebbles for the Zeer pot to "lock in" moisture? I saw pics online of Zeer pots with small stones or pebbles on top.
Just a suggestion but would it not work better to put the water in as you add the sand? I.e. put down a layer of sand, dampen it, then another layer of sand and so on. It seems to me it might help the water penetrate the sand more evenly.
Yes, it can. Depending on the temp, you might want to use small fans directed at the pot. I use those little computer fans by OPOLAR (Amazon). In the summer it can be a distinct advantage if you live in the desert - to keep them inside.
It should be a cool EDUCATIONAL project, doesn't matter if it's performed by people being schooled in any particular way. However, if the student is attending any State accredited education system then they WILL already learn about this and will likely have a similar experiment several times during their education. Cooling due to evaporation should come up as a topic focus in several different years of schooling, at least it does in the US. I'm not sure where you are speaking from, but if your education system isn't already covering such simple topics then the system probably needs to be improved quite a bit.
Nice video man, but i have 2 questions. First is about sand, can be used also for warming by fire in a different situation? i mean , the sand have 2 options? (i thought sand is always for warming) And the 2nd question is, if we use that pot refrigerator need to fill it again with water about 1 time each day? thx!
have you ever bought Grin Workshop tools? I have a few and if you can get a large tin of Altpids you can put about 4 to 6 of their cards in it. if you do do I would like to see a video on you using them . in joy
From all the zeer pot tutorials I found this most informative and successful. You raised logic points and didnt made common mistakes, way to go.
Thank you, for the comments and support

You can use a glazed pot for the interior chamber. The moisture from the sand evaporates through the exterior shell, but still pulls heat (exchange) from the interior sealed pot. It's actually the best choice to have a glazed/sealed interior smaller pot, because then you can use salt water, waste water. If the interior pot is porous, then you must use potable water.
have also seen old enamel pots used as an inner pot. With a well matching lid, they keep out insects (assuming you plug the steam vent).
Yes, that's obvious when you think about it. (I hadn't thought about it.) There is absolutely no benefit in having a porous inner pot, as no evaporative cooling happens there. The evaporative cooling happens in the wet towel on top, and from the sides of the outer pot.
How would it work if you had sealed aluminum metal pot on inside?
The sand and outer pot do all the evaporating and heat extracting, the aluminum pot would do all the receiving of the heat draw.
Salt should decrease the temperature more vs plain water
Don't want at all to use aluminum 😢@@michaelszczys8316

Great video. I would even try pre mixing the sand and water, to avoid over saturation. Also wet sand is easier to handle.

from what I've read/heard, the inner pot should be sealed (no drain hole) and have a vitreous glazing that will keep the moisture out of the interior pot. The out pot should be unglazed, and could even have small holes to aid the evaporation process.
make some videos on what you have heard
Does this have to stay outside or will it still keep freeze inside
So you put it directly under sun or in the shade? Did you try it directly under the sun?
I have a question. I have one of those big huge plastic water barrels, that I’ve been afraid to use because of the ratio of bleach, etc. I now live in a desert. I’m wondering if I could take that barrel surround it with these rounded decorative paving bricks that I have creating a blank space donut in between the brick and the barrel lining it with plastic tarp filling it with sand and covering it as this demonstration describes with a concave lid, to keep drinking water cooler and therefore less likely to grow baddies. Comments?
Great video. Would florida be too humid? I read that people are using this process to actually keep their insulin cool in places without electric. Insane. Again Great video!
Will this work in cold climates?
how long does it stay cool for?
Perfect mate, great job
Would this work with wood instead of clay?
Cool! Thanks for the info! 1 question though, about how often do you need to add water?
when the top layer of the sand is dry and no longer damp
Ok, easy enough. Thanks!
I would start with wet pots already soaked in water, and add damp sand instead of dry sand.
This gets the evaporation process started quickly.
Hi Corporal. Can you combine sand & pebbles for the Zeer pot to "lock in" moisture? I saw pics online of Zeer pots with small stones or pebbles on top.
Will it work with very large Ceramic pots? What I mean is...within reason, how big can you make these?
Just a suggestion but would it not work better to put the water in as you add the sand? I.e. put down a layer of sand, dampen it, then another layer of sand and so on. It seems to me it might help the water penetrate the sand more evenly.
sounds great, thanks for watching
Hi, can it be used in side of home or just exterior. Can it be indirect sunlight or shade. Thank you.
Yes, it can. Depending on the temp, you might want to use small fans directed at the pot. I use those little computer fans by OPOLAR (Amazon). In the summer it can be a distinct advantage if you live in the desert - to keep them inside.
Nice one Corporal.. great work and very well presented X
+liz morrison Thank you and thanks for watching
Would you get a better cooling effect if the pot was partially buried?
Question - Why have a non electric frig and put a electric fan on It? Will it work without the fan? Say outside my camper?
I built one. Outside temp is 62 f. Inside the pot is 68f. What am i doing wrong? Built per your instructiona
This would be a cool homeschooling project.
It should be a cool EDUCATIONAL project, doesn't matter if it's performed by people being schooled in any particular way. However, if the student is attending any State accredited education system then they WILL already learn about this and will likely have a similar experiment several times during their education. Cooling due to evaporation should come up as a topic focus in several different years of schooling, at least it does in the US. I'm not sure where you are speaking from, but if your education system isn't already covering such simple topics then the system probably needs to be improved quite a bit.
Nice video man, but i have 2 questions. First is about sand, can be used also for warming by fire in a different situation? i mean , the sand have 2 options? (i thought sand is always for warming) And the 2nd question is, if we use that pot refrigerator need to fill it again with water about 1 time each day? thx!
have you ever bought Grin Workshop tools? I have a few and if you can get a large tin of Altpids you can put about 4 to 6 of their cards in it. if you do do I would like to see a video on you using them . in joy
Might be a repeat question, but what about using wet sand to begin with?
