I once spilled an entire glass of water into the keyboard of my macbook while it was on. It automatically shut off. I thought I was hosed. I almost smashed it on the table in fury. Luckily I didn't. I quickly removed the battery, took the computer COMPLETELY apart, and blow dried it for a few hours. It came back on and has been working ever since like a charm. Its been over 5 years now. Same with an iPhone 5s. I dropped it into a glass of water. It didn't work for awhile but came around after a few days and worked fine afterwards.
