Help! Macbook air 11'' cooler won't work!

Hey guys!

Last week i was drinking a lemonade and dropped a bit of the juice on my laptop. It suddenly turned off and then i got desperate.

I took of the excess of liquid and put the laptop on rice as people told me, to take off the humidity. I waited.

Then i turned on and it seemed great. Except that a bit of rice got stuck inside the Macbook. I just didn't mind about it and was using it perfectly fine.

Today i turned the macbook to one side while turned on and it seemed like the rice went right into the cooler. It suddenly stopped and won't come back to work again! The Mac is fine, turns on, works great, but the cooler won't spin. I don't know what to do. I was thinking about opening the mac and take off the rice, but i don't know how to do it.

Can someone help me please? Sending it to apple would probably cost me too much. I'm 16, not working and can't afford it. Thanks guys.
