You get to buy a new keyboard for Christmas.
Sorry. If you are very lucky, the keyboard will dry out and work properly again, but I suspect that, to be this lucky you will need to disconnect the keyboard, and hang it up in some warm air somewhere to allow it to gently dry out.
Or perhaps blow a warm, (not hot), hair dryer over the keyboard, when it is disconnected of course.
I wouldn't use the keyboard again until the sticky keys have been cured as you will only make it worse.
But all this is only if there is no permanent damage to the circuit board already.
I have a really serious problem, I accidentally spilt soda on my Dell Inspiron 8600 laptop yesterday. My girlfriend was sitting by the computer and drinking and I didn't see her glass and **** the soda went all over my keyboard. I have tried to remove the keys one by one and cleaning the surface below and most of my keys sound and feel as normal, though a few are very hard to press down and are staying pressed for some time before popping up again. The other big thing here is also that if I press the A key i get response from other keys that are not even close to the A. For instance if I press the A key the result I get on the screen is "FHA"!
Please.. if someone can help me how to solve/improve on this I will GREATLY appreciate it!
