The principle is pretty simple. You just have to maintain the vaccum in the inverted tank which typically will maintain itself as long as you don't let the water level get to close to the rim of the inverted tank.
Try a google search for fish bridge and you will find other examples of the principle in practice.
For your own curiosity, take a glass full of water and place a bowl on top of it, then flip it & fill the bowl with water before the glass can drain. You can then lift the glass up to near the surface water level & still maintain the water level in the glass.
It's best to attemp this over the sink :hehe:
BTW a water cooler works on the same principle.

As for the air bubbler, I suspect that it's a aqualift type pump that pulls the air out, then they have it set up to recycle the air back into the bubbler thereby balancing the amount of air pulled out vs what's put in to keep the water level constant in the tank.
