try immersing your macbook in dry rice and leave it overnight as the rice will absorb the moisture. My friend fixed his cell after he dropped it water this way.
If you dont want to make the big investment in an espresso machine consider getting a moka pot. They run only about $40, make great espresso coffee, and lookgreat on the stove when not in use. I bought one a year ago and thoroughly enjoyed it. http://www.bialetti.it/uk/catalogue/scheda.asp?id_cat=24
