i think it goes without saying that FIRST would never be so reckless as to make a "water" game and use water... they would probably use mineral oil as it doesnt conduct electricity but this would bring on a host of new problems such as the cost, how much of a pain it would to work on an oily robot, teams access to large quantities of the oil, and if the robot tips, relays and plugs would be covered in oil and no longer work unless thoroughly cleaned... so yeah barring hassles and cost no liquid game
