Agreed. Had a good time but I feel kinda guilty about it today. I have run across many rattlesnakes in the wild and just let them be. In the backyard, now, that's a different story. When I was in Boy Scouts about 55 years ago, we used to eat fried rattlesnake - flaked like fish and tasted like chicken. And I've had rattlesnake chili at a chili festival. But I never kill snakes without good cause. Last time was when I killed a coral snake in the yard when my son was a young child (he found it).
I went to one of these back in the 70's, in Sweetwater, Texas (which actually gets its water from Bitter Creek). But I don't support them now. The snakes control rodents and other pests and simply shouldn't be killed indiscriminately en masse.
"They also used an instrument called an electrocautery, which ignited the oxygen." The engineer in me cannot let this pass. Oxygen does not ignite - it causes other materials to ignite. Natural gas would ignite, but not oxygen. Its danger is that 100% oxygen causes ordinary materials like cotton to become quite flammable. If our atmosphere were 100% oxygen instead of about 21%, forests would auto-ignite.
These devices simply work by evaporative cooling, which will keep food as much as 30 degrees below ambient temperature, but they won't keep food 'cold'. We made jello with one of these things about 55 years ago in scout camp during the summer in central Texas - furnace hot but not very humid. And while they work as intended in areas of low humidity, like deserts or high elevation, they don't work at all well in humid areas such as the Texas Gulf Coast. We don't have root cellars here either.
