I learned this in Boy Scouts in the 1960s. We were assigned the task to boil an egg using a wax-paper bag and a cooking fire (camp fire). No problem so long as you’re careful not to let the flames touch the bag above the water level.
I used to recycle plastic for a living, about 15 years at it. Do not drink the water. Wash your hands, feet, ass, but not in the oatmeal. As for the baby bottles made from lexan, hdpe, ldpe, and whatever, just wash it, don’t boil it. Teaspoon of Clorox in the dishwater.
Jokes aside, that is what a thermoplastic is, some thing that will change, or, become pliable, with enough heat.
The first ever thermoplastic was what? It wasn’t man made. It came from nature.
I’ve seen water heated over a fire in a paper bag. Neat. Eventually fell apart, putting out the fire.
The practicality of the demonstration was not provided by the person doing it.
Natural thermoplastic? Heat sugar enough and you can get anything from solid glass to taffy to syrup. Thanks, you made me think.
What else where you thinking of?
The Plains Indians used animal hide stewpots above an open fire. And I can understand the paper bag — paper’s kindling point is 451 Fahrenheit and water boils at 220. The plastic bottle trick in the video is … interesting.

You can even do it in a plain brown paper bag if you’re careful.

We boiled eggs in paper cups back when scouts were boys.

But I don’t LIKE boiling water. It burns my tongue!
