I learned a new trick today. To make a stand for your 510 tank:
Get an eye dropper bottle cap and pull off the glass part.
Pull out the rubber bulb and cut off the closed end leaving a tube about 1/4" long with the flat portion attached. push the tube and flat portion in the opposite way so that the flat portion rests on top of the cap. Voila! a stand for your tank. The rubber actually grips the threads on the bottom of the tank.
