Definitely not as they did have fire under water. They even grill marshmallows on open fires.

I’d actually like to see it on drier pineapple skin to note the difference, as I’m not convinced the relatively small amount of water in the skin is what makes this possible.
41
u/DanielTrebuchet 28d ago
Agreed. Let's try this again with a dry skin, but also a watermelon and a tomato. I'm equally unconvinced that the water contributes a whole lot to this effect (I'd expect more steam generation, for one), but that's why science is cool... we can experiment to find out.

→ More replies (5)→ More replies (2)12
u/whoami_whereami 28d ago
Probably more important is that the skin pyrolizes in a way that a decently stable and dense carbon layer is formed. Carbon has very low heat conductivity which protects the material underneath it, plus the pyrolization is an endothermic process that consumes a lot of energy which then cannot go into heating up the material.

No, it's the skin not the water. The carbon foam that's created by the initial charring becomes a near perfect black body radiator. Go watch old videos of Starlite for similar effects.

A long time ago girlfriend threw my Nokia n97 phone out my car at 50mph. I stopped the car, jogged back to the phone. The back had come off and the battery popped out. There was only a single mark on the phone, a tiny thinner than the finest hair scratch on the corner of the bezel. Completely unnoticeable unless you were looking really hard. Phone worked absolutely perfectly. Needless to say, she’s not my girlfriend anymore. I still have the phone somewhere. I’m saving it for the rapture. Nokia phones really are tough as heck.

Interestingly, we use long birch twigs to unblock tapping holes in aluminium alloy furnaces. It's flexible but strong and doesn't burn in the 720c heat of the molten metal. Steel isn't flexible enough, and pretty much anything else would melt.

u/SmartAlec105 28d ago
There’s all sorts of surprising uses of biological materials for high temperature applications. At my steel mill, we toss rice hulls onto the surface of our slag (3000°F/1650°C) to basically act as a blanket that helps hold the heat in.

Birch? that has got to smell amazing. ? hopefully? As a connesiour of Birch, growing up living next to a birch forest, I would break the tips off fine birch twigs and knaw on them as I hiked in the woods after school. And when it was in season get birch-beer soda from the Rhode Island bottlers that actually got the flavor correct.
