Derrill and I are busily turning out Thermo-nators and Kool-water bags.
They work on the principle of evaporative cooling. The canvas allows moisture to seep through, and as that water evaporates, it brings down the temperature of the water inside. I don’t understand how it works, I just know that it does.
Not only that, it’s made out of renewable materials and helps keep plastic water bottles out of landfills.
When Derrill and I were young, canvas water bags were ubiquitous in the southwest. You’d seldom see a car traversing a long stretch of desert highway without a waterbag hung on the antenna or hood ornament. But with the advent of plastic thermoses and in-house icemakers, they pretty much disappeared.
Here’s how we came to be making them: Derrill wanted to find a water bag to take when we went out on our ATVs. I searched online to find one for his birthday and ended up buying one on Ebay that was probably as old as I am. It was in pretty tough shape (kind of like me), but after he replaced the grommets, we took it out with us. Sure enough, even when the temperature was nudging a hundred, the water in the bag stayed cool.
As I had searched on line for a bag for Derrill, I found other people who were asking where to get one. It seemed that no one was manufacturing them. Until now.
So, if you drop by to see us, check in the shop. (I call it the sweatshop.) We’ll be there, churning out Thermo-nators and Kool-water bags.
