I just bought one of those Coleman tents. Small leaks like you showed in the video do not discourage me. As other viewers suggested, just get some waterproofing for those areas. Surprisingly enough Thompson's Water Seal has been suggested to waterproof the tent. I've also seen Silicone dissolved in Mineral spirits.

Works much better in low humidity environments. I've seen these drop the temp almost 40 degrees in the desert. Also, put the pot in full shade. And you can use a small solar powered fan to help speed evaporation.

Zeer pots do not work well in humid conditions. Nor if they are in the hot sun. ONLY use distilled water! Minerals in tap water will clog the pores in the outer pot. They can only drop the inside temps about 20F or so but there are limits. Bigger the outside pot the cooler the inside will become. But you keep the inner pot it's original size. Inside pot can ge glazed but outside pot must not be glazed. He is conducting heat from the ground into the bottom of the zeer pot. A Yakhchal might be a better solution. There IS another way to refrigerate and even freeze that does not require electricity - ammonia refrigerator. The old ice cream trucks that sold ice cream in neighborhoods used to use an ammonia system. Very efficient and you can freeze things too. You only needed a heat source, Modern problem is in getting the ammonia. It is also called R717 if not mistaken. And the meth makers use that to make their product so it is hard for a normal person to get, if at all.

A Zeer pot is a simple evaporative cooler that can be used to preserve food in hot climates. Here's how to make and use one: Materials: Two unglazed terracotta pots (one smaller than the other) Sand Water A cloth (to cover the top) Food items to be preserved Instructions: Preparation: Ensure the pots are clean and the smaller one fits inside the larger one with some space between them. Assembly: Place some sand at the bottom of the larger pot. Position the smaller pot inside the larger pot, centered. Fill the space between the pots with sand, packing it tightly. Activation: Pour water into the sand-filled gap until the sand is thoroughly wet. Cover the top of the pots with a damp cloth. Usage: Place the food items inside the smaller pot. Keep the Zeer pot in a dry, well-ventilated area. Regularly add water to the sand to keep it moist. Re-wet the cloth cover as needed. How it Works: The water in the sand evaporates through the outer pot, cooling the inner pot and its contents. This process helps to keep perishable food items fresh for a longer period in hot environments.

Lol, I was just about to comment about humidity being the limiting factor as far as how cold it can get. Check what the dew point is for your area, that’s the coldest it can get. I was also about to mention the hole in the bottom of the pot. But the main principle that makes it work requires that the outside pot be porous AND soaked. THAT is what enables evaporative cooling. The wet sand provides additional water to replace the water in the outside pot walls, provides a mass to store the cooling, and transfers heat from the inside pot to the outside pot. But it doesn’t contribute much to evaporative cooling since there’s no place for the water to evaporate to. In fact, the wet towel blocks the only exit point. The pot inside doesn’t need to be porous. Being in the shade definitely helps. Finally, airflow multiplies cooling effect tremendously by increasing the evaporation rate. Great video, hope this helps, and good luck.

I did the exact same thing and got the very same results.

Consider sealing the hole in the bottom of the bigger pot so the water doesn't drain out.

The underground temp is 55deg f. Not sure how deep you have to go.

Great tip.... remove the elastic and use paracord 💪🫡🪖🇬🇧⚔️

Soak the external terracotta pot submerged in water for a couple of days before you do this. Terracotta is porous and you want to trigger evaporation from the whole surface of the pot. Humidity also has a massive effect on this method. The internal pot is also better if it has a very small opening compared to the average diameter. Be very gentle when removing the cloth too, you want to minimise disturbance of the cold air.

i have heard of using alcohol or petrol instead of water

One quick hint, those thermometers take an average of the surface it can see. on the front (that you point towards what you want to measure) you will see a cone shaped hole, anything that the sensor at the bottom can see will be averaged, so it reads better the closer it is. The red dot (if it has one) is not what is reading the temperature it is the sensor at the end of the cone. .

I want to give a sincere thank you for all of the comments. I recommend viewers look though the comments below for some amazing information and knowledge.

So the Egyptian qullah, or kullah, has existed using this for thousands of years. The key is maximizing the external surface area, and minimizing the interior space. Typically the outer pots would be wrapped in a wicking cloth to try to increase that area exposure to breezes. This of course is best in a dry climate, as low humidity is the key principle in action here. These would also often be placed at locations that had funneled the prevailing wind to a covered area where these would be set. In modern technology we have some advantages in materials. You can make structures of thin corrugated cardboard where the air can pass through the channels in the paper. The paper will wick water from the pot and thus cool it. We can also take some advantage by using phase change materials, heat pipes, and even micro-solar with peltier cooling to even get evaporative cooling vessels down to freezing temperatures with no external power required. To hit your maximum cooling effect you want it to exist in the shade, you want as much of airflow as you can get, you need to saturate the pots (it takes a long time to for clay to completely saturate), and consider putting a clay pot base as a lid, then wrap towels around the entire pot (your goal is to wick the moisture out of the outer pot as much as you can). As water changes phases it actually requires a slight jump in energy to go from liquid to vapor, this energy comes from the heat of the pot. So the more evaporation you get the cooler it gets. For future videos I would recommend having two pots side by side. One as a control that you add no water too, and one with the water.

Evaporative coolers really struggle to cool items off once they're warm. They do, however, really help to keep cool things cool. Some tips would include having a tray underneath the big pot that the sides are just lower than the bottom of the inner pot. The hole in the inner pot doesn't matter as long as the water isn't so high that it's coming up through it. Fill the tray with water and keep it full. Let the corners of the towel soak water up from the tray as well (some fabrics are better than others at this. I have also put a water bottle with a tiny pinhole on top of the towel to keep it damp from above as well. ALWAYS shaded, as much airflow as possible, and these take TIME for full effect - you won't achieve maximum cooling until the second or even third day. Be attentive - if it dries out, you're starting over. I live in a super dry climate. My home is cooled evaporatively and I regularly get about 25-30°F temperature difference outside to inside. 15% humidity or less is not unusual at all. When the humidity is up a little, around 40%, I struggle to get 20°F difference. If it's raining, it's hard to tell that the cooler is even on.

Dig a hole and place the pot in the ground. About 16 feet underground.

Try using dirt instead of sand and also bury the pot in the ground level with the ground

Oh my, If you really needed to keep something cold the very last place to conduct this experiment would be under the blazing hot sun! Lol, really?

Soak the terracotta pots for several hours in a basin as they are porous. Since you have everything assembled, you might set it in water just deep enough to accommodate the assembly. Staring with wet sand in a dry exterior terracotta pot seems like it would take the evaporative effect longer to occur while the water permeates through the terracotta from the interior to its exterior. Just a thought. Regards, afishyfella

Try this in The shade where there's no breeze and in shade with breeze.

Try something but in the ground

20 to 25 degrees cooler is potentially life saving.

20+ degrees cooling is good for evaporative cooling. The ancient Pershians built high towers with vents on top to create breezes from warm air rising. They would take advantage of the nighttime temperatures by cooling things down and shielding them from higher daytime Temps. They might put things in a pit, below the hot ground.

I felt bad for you when you kept saying how extremely hot it is and will be even hotter tomorrow and you can leave the house or do anything in this heat. Then you told us the temperature. Thank you for the hysterical laughter you gave me, 94F is the most perfect temp you can have. I dream of every day being 94FC. Now if you said it had been 106F or more for a few consecutive days then yeah I'd agree but not that cool.

So...........evaporative cooling?

That moment when you realise you're a fuckwit.

You need a breeze.

Think about how the metal tarp pole lightning rod you nay use for your tent or tarp!

My grandmother used tocmake jello in their well on the farm, they later on build a cold room to store eggs in based on this principle, they usd ash instead of sand, so air would move through it, Never tried this, but will definitely try this myself👍🏻

Just putting a wet sock over a water bottle will make it noticably cooler. Make it go from undrinkable hot to tolerable.

I hear west Pa. In your voice. Enjoyed your video.

can I ask you what type spray did you use ? thanks a great info video

Look like they will work...But I'm going with something like the Green Elephant telescopic pole's that you liked so well in your other review so I can get the exact height I want..

good video!

Just found your channel and it's really helpful. Also it's nice to see a stand up guy. You seem to be a great person.

The Coleman Weather Testing facility...looks like a great facility, but I would suggest they perform their rain test for a longer duration than 10 minutes; something closer to 30 minutes. : czcams.com/video/uhCtA3DSf40/video.html

I wish Coleman would just use an internal factory taped seam design on that wall / bathtub floor seam. They do this "tuck and sew" type of design, claiming it is very weather resistant; obviously not waterproof. Seems to be a hit-and-miss; some report very minor leakage...other report none. I'd seal it first thing just to be certain. I have the "Coleman WeatherMaster Screened 6" tent, bought a while back. Have not had opportunity to use it yet...only did a test pitch once in my back yard in great weather. I'm sure the factory waterproofing treatment was fine, but I went ahead and hung up the Rain Fly and sprayed the external surface with Adsko Silicone Waterproofing - my favorite to use. First time I use it at camp, I will target a time of 3 - 4 days of great weather and immediately spray a good coat of Adsko along that floor / wall seam on the external, and completely seam seal that internal sewn seam. On the WeatherMaster, all of the seams on the underside surface of the Rain Fly are factory taped With that, I should be quite fine...as the WeatherMaster already has a great reputation for handling inclement weather very well.

If you put some clear silicone on the seams, it will seal them, and probably be fine. I think we should all keep in mind that tents are not made of Gore-Tex.

cheers mate ive been trying to work the poles out since I took it out of the bag it now goes back in perfect easy when you know how great vid

Not good when the proof of concept fails!

The train fell over?? What!!??

We used to explore deep into Fort Knox military base in a stealthy manner..it was like going back in time with the behavior of the animals since most haven't ever seen a human in those deep forest.. most were extremely courteous and would get closer. We had some amazing times exploring that base.

How does under quilt attach with bug net attached? I guess put bug net on after underquilt?

nice video..and I agree this is very comfortable cot, just as comfy as my huge coleman one that takes up half the car!..I've slept on it now 15 days over multi trips..I put my sleeping pad on top when it's colder..the plastic and poles are heavy duty..I wish I could secure my sleeping pad..there are o rings under the mat, not sure what the purpose of those are maybe I could rig them somehow to hold my mat..and I notice that they now have a cotton top quilt now..which I might pick up..I probably wouldnt take this back packing..with limited space..but for the canoe and car camping this is the best

Get a Toyota next time lol

Dang..... I had to snag all of them, although the hat is now $4.49.....highway robbery, Just kidding. I have bought a lot of gear off of Temu and have only been disappointed a couple of times, usually due to materials being too thin. I subbed.

IT didn't do alot of water in that tent . That little bit of water wouldn't ruin my camping trip . That was some really hard rain too . Maybe do some water pruffing before you call it quits on that tent .

Drive the speed limit 🙋🏻‍♂️🇺🇸
