How can I get rice out of my Macbook Pro?

Hi everyone,

a couple week ago, I splilled some juice on my Macbook Pro. I turned it off, whiped as much juice as I could and put my Macbook in rice. Since then, everytime I move my computer, I can hear the rice go through the whole body of the Macbook. I was wondering what would be the safest way to clean the rice out. Should I go to my nearest Apple Store or should I open it myself? Any suggestions are greatly appreciated!

Thank you
