I can hardly believe my eyes! I helped do some related research specifically concerning thin-film drainage from tubes, way back in my undergraduate days: https://doi.org/10.1016/j.expthermflusci.2018.04.015
I also handed in a solution for a similar problem in a university Physics competition.

11th problem here:

I was the only one who handed in a solution for that particular problem, it was scored 70 out of 100. I no longer have my solution, but I doubt that it was very accurate, and I didn't have time for experiments.

Interesting!

For the wok example, I recommend just putting the wok back on the stove for a few seconds and have the thin water film evaporated, before quickly coating it with an oiled tissue, and store it hot. It takes 30 seconds max.

Why didn't Professor tang just put the wok back on the stove for a few seconds. That'll dry out it out fast and you can see the film disappear.

Under careful supervision, the wok won't even get anywhere near 100C

Trump is going to forbid this wok research
Shake it off and it will finish drying a lot faster.
Oh academia, trying to find scientific truths and end up just being pragmatic.

I know they'd take offense to such things, which is why I say it.

This is no different from a mom blog, yet because its academia, we pretend its valuable. Adam Ragusa-like people could/should do this study. We should value it as much. As long as its replicated, good for me.

And let us not pretend there is some sort of pure magic that happens in a lab. I'll take 10 average joes replicating a study over 1 lab unreplicated. (FYI that is the scientific method, Appeal to Authority is the opposite of the scientific method)

Hint: it goes faster if you don't watch.
I could see companies adding a PFAS like coating on the inside of containers, and then sell them as completely emptyable containers.

And unless you tested flourine pollution, you'd never know.
