Rice does too work!
You have to leave it overnight under your pillow. The rice fairy comes in the wee hours of the morning, takes the rice to cook for her hungry little fairyettes and magically fixes your mods in gratitude for the thoughtful gift.
From
@Mooch's blog linked above:
"It's clear that burying anything in rice just slows down the evaporation of any water that's present. This makes sense though. Rice can't vacuum up water. It can only absorb any water that evaporates and touches the surface of the rice. Even then though rice is a lousy absorber of atmospheric water.
"Since the device that is wet is buried in rice, with no air movement, the humidity level quicky rises up to 100% next to any water that is present inside the device. This significantly slows down any evaporation that could take place.
"Adding air movement blows away the layer of very humid air above any water, allowing the water to evaporate much faster.
"Some of you might have tried using rice and found that you could turn on your mod a day or two later and it worked. But did you open up your mod to see if the water had actually evaporated? How can we know that the rice did anything?
"Bottom Line: If you have a mod that got wet, do not turn it on. Remove the batteries (if possible), shake out any water you can, and then place it in front of a fan. Rotate it every couple of hours to try to get any blowing air into any seams or ventilation holes. It should be pretty dry internally in 24 hours.
"Please don't bury it in rice!"
