Testing a vintage self-cooling bagfrom @theironsnail

Apparently, this 100 year old water bag will make water cold without ice. It was oftentimes used in the desert, on fields, when you're farming, stuff like that. Today, we're gonna see how well it actually works. Rough life. My microphone died for a second. It comes bad. But tier, I was saying that I'm pretty sure this is a 100 year old bag based off the prints on the front and then I think it was repaired in the tier or sixties and now I'm using it today. This is a linen canvas and you need to soak it for at least twenty four hours so that way the yarns and the fibers swell up and make the bag almost water impermeable. But water does need to seep out ever so slightly. Our sack soup is done. Oh, stinks. What the heck? Okay. So now let's see if it makes water cold. Okay. So the water is tier, 98 degrees Fahrenheit. Alright. So it's actually kind of a good day for it, a little windy. It's probably 80 plus in the sun. We'll set our sack out. It's dripping a little bit. That's okay. It's a 100 years old. You'll drip too when you're a 100 years old. Rank what's going to happen is the heat and the wind will evaporate what is seeping outside of this bad, pulling all of the heat out of the water. So it went in at 98 degrees. It's 80 degrees outside, so that should even out. If it gets to 60 degrees in there, I'll be very impressed. And this is gonna be our control test. See you in a second. Okay. We're back. Apparently, you're supposed to do this in the shade, so I moved it to the shade, but now it is time. This feels ice cold. This feel Oh. Okay. Our control test is best about the temperature, 79, 78. Now the bag. Very excited, very excited, very excited. Just like grandpa used to do it. Wow. Look at that. Science in action. If we were in the desert and it was really dry, I think it'd be a lot more dramatic, but that's still pretty significant. No, bottoms up is actually fine.
