Heron's Fountain

[TinselKoala]

Well, actually I was thinking that the ppballs were less compressible than the same volume of unshelled air... essentially solid objects at the small pressure changes involved. So I figured that they would help by reducing the energy storage in springiness and just allow more direct transfer of the pressure from the bottom bottle to the water in the top bottle.
I was hoping that they would just be simple displacers and I wanted to avoid energy storage in compressed air. But actually I haven't done a rigorous comparison with and without the balls. Easy enough to do, I'll probably set up and test later tonight or tomorrow morning. Since it's pretty clear that I blew my chances at winning the Self-Powered TableTop Water Pump challenge..... ho ho ho..... there's not much else going on.

TK:

Well, I was looking at my replication and was thinking that since I used those plastic bottles, they can hold some pressure as well as a vacuum.  I am thinking that this helps somewhat in this process.  I read that Heron used copper vessels for his device so, we might have a slight advantage here with our replications.

...not as far as the Buddah is concerned.

Well, I was gonna wait until Bill posted his video of his fountain, but after that last set of drawings from johnny874 I feel rather obligated to point out that I published the video below on YouTube on August 25th.
