The exact same thing happened to me in December, except it was a cup of paintwater and brushes. It's a terrible thing to discover, I'm sorry. Unfortunately, my guess is that your logic board is probably fried. If you haven't tried powering it on you may be okay, but I would place your computer in a bag of rice immediately. I never was able to get mine functional again, but it did "zombie itself back" a little by making some random noises and flashes when I turned it on. I would reccommend taking it by Oynx in Decatur. They will be able to tell you what kind of damage you recieved. It'll cost you $40 or so, but it's always good to know exactly what issues exist.
Also, if you have unibody, the battery isn't that easy to just pop out.
