i jumped into a lake while hiking forgetting about my camera. the rice does dry it out. Problem is i didnt learn about the rice till later on when i got home. First thing you do when getting it wet is turn it on. You get a light and then a frying noise. thats your circuit board frying, making the rice later on useless except for drying out device to sell it on ebay for parts (30 bucks yay)
Rice is a very effective drying medium. I am allergic to towels, so after i shower I rub uncooked rice all over my wet, naked body. There are a couple downsides to this method. First, over my lifetime I’ve probably used enough rice to feed a small Vietnamese village for a year. Second, I get a lot of rice stuck in hard to reach places, and I have to either rinse it out or rub it out with a towel.
