Narrative:

After leveloff at cruise altitude of FL190, flight attendant entered cockpit to ask if we would like anything to drink. First officer responded yes and handed his nearly empty cup of water to her and requested a refill. After grabbing the cup, flight attendant dropped it on the center console. Very little water spilled and we immediately cleaned it up. A few mins later the cabin altitude began to fluctuate, climbing and descending. We initiated a descent to an altitude below 10000 ft and while descending, the passenger oxygen masks deployed and passenger put their masks on and the flight continued to destination without incident. Overall, even though everything turned out alright, it can never be emphasized enough -- be very cautious with liquids around electronic components.
