it's called a dessicant.

and it's not controversial if everybody agrees it works.

you are in the minority here and you must support your position with facts.

EDIT

In fairness, I think in the last year we've moved beyond accepting a ranting guy on youtube as evidence.

I've actually seen this guy and he's great on many topics. I can see, and appreciate where he's coming from but I don't think it disproves anything.

Possible conflict of interest that should be declared is this guys fixes devices for a living and charges for the service.

>and it's not controversial if everybody agrees it works.

Well, people agree in all kinds of crap like homeopathy.

Many (most?) agreeing doesn't make something "scientific". Proof does. And it's those proposing a mechanism that must bring that proof.

Uncooked rice works as a desiccant and is found in most homes. If you wrap the phone in a paper towel there is no need to worry about rice residue or rice dust getting into the phone. It does work, but it takes 24-48 hours to dry your phone. Silica gel or other desiccants work better, but most people do not have these in their home.

Did you just cite homeopathy?

Did this just happen. Did you just strawman me?

No... you were the one that was using "everybody agrees it works" as the support of your position. He's offering an analogy that, rightly so, makes your position completely unsupported. If you're willing to say that homeopathy is crap despite the volume of people that support it, then you have to admit the same about your own argument. Provide evidence or support, not appeals to the masses.

Nobody agrees that homeopathy works what are you talking about

Stop being intentionally obtuse. You were the one that said keeping a phone in rice works because "everyone agrees that it works". That's circular logic. He was using that same logic with the example of homeopathy because, much like your rice trick, the only support of homeopathy is that "everyone [who believes it] agrees that it works".

You're wrong. Stop trying to wash it away and just admit it.

It's a common sense to me, but if you want, we can do the math. Should be pretty easy to calculate humidity and rice desiccant properties to end this joke once and for all. Logically, it should be better to let phone dry in open even, instead of creating closed space in the bag of rice.

You can watch the video muted btw. PCB condition shows clearly the level of corrosion from just a little bit of moisture.

"If rice is placed in a sealed container, the air in the container will gain or lose moisture until it attains an equilibrium relative humidity (ERH) corresponding to the rice moisture and temperature."
