Take the second one down, stand it upright, and fill it with coffee beans! ;^) Actually I'm not kidding much. Years ago I designed 32 attack robots for a game and one of them shot scalding hot coffee as her weapon. (The space station had been taken over by an evil entity and the good worker robots... secretaries, janitors, welders, and hydroponics workers... were all converted to serve as mobile weapons. It was fun to think up what would be needed to maintain a station and then how to make it deadly.) Carolly
