Quote: Okay, but doesn't there have to be a seal around the top where the bottle is at the top of the bucket to accomplish that? Or is it just having the neck of the water bottle under water that accomplishes the seal?
The latter..... take a drinking glass and fill the sink then submerge the glass then lift it up by the bottom without leaving the water.... Air pressure keeps it in the glass... pretty cool stuff.

Okay... duh
I knew that. Somehow I just couldn't "see" it. I use this principle with my home made glass waterer.
Now I'm wondering if there is some kind of frame up there that holds the top of the bottle up from the bottom of the bucket higher or if the water container is just wide enough to catch on the bucket and keep it up higher all by itself.
