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.
