The Anti-Grav tables in 8-Rear are specially designed to compensate for the ship's motions, minimizing drink spills while under enemy attack. Theoretically, one could drink an Alien Secretion during a hull breach and still not spill a drop. Of course, one's eyeballs would implode within 2.3 seconds, but if and when one would make it back from Sickbay, the drink would still be there. The Anti-Grav tables are usually accompanied by one or more Anti-Grav Seats.
