The keyboard isnt working

hey everyone! i have to fisrt say sorry for my english,

the problem of my macbook is something that i dont understand, but i can tell details.

3 days ago, i was working really good, then one day i run with water to put some to a plant that was dying in my room, and sadly like 5 droplets fall into the keyboard, i didnt do anything , i just clean it because they where just 5 drops of water (truly). an hour later, y realice that when i press on the "caps lock"and the green light stays, no key would run and when i minimize some windows, they just minimize but sooooo slow. THEN! when i press of the caps lock, every key work perfectly and every window minimize normaly. i realice that just some keys are malfunctioning (with caps lock off), when i press s it would appear s &g ; when i press w it will appear w&t, when i press 2 it will appear 2&5, (this keys are separated by two keys).

I went to technical and support centers , and they say its circuited and that probably cost me $ 400 to fix. I'm working on my thesis design , so I 'm desperate . My macbook is my job tool. :( hope i find answer here. :) thank you!
