Testing a vintage self-cooling bag from @theironsnail

The creator introduces a 100-year-old self-cooling water bag and explains its historical use. He prepares the bag by soaking it, then conducts an experiment by filling it with 98°F water and placing it outside alongside a control bucket. After one hour, he measures the temperatures, demonstrating that the bag successfully cooled the water to 64°F through evaporative cooling, a significant drop compared to the control.

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.
