Inspired by Steve mould, I had some fun doing something quite similar a while ago experimenting with Bell Siphon, 3d printing, and numerical simulation. If this interest someone here I just pushed it to Thingiverse now https://www.thingiverse.com/thing:5948252 https://www.thingiverse.com/thing:5948252 https://www.youtube.com/watch?v=S748mcM0MSg https://www.youtube.com/watch?v=S748mcM0MSg As Steve showed, it's particularly important to take into account both air and water. There is still some work needed to make it Sim2Real and optimize the design automatically. The ambitious end-goal, is to have a cascading siphon (not so dissimilar than the flushing mechanism in your toilet) that can reliably be switched on by a single additional drop of water. (Currently I achieve this goal using a Shishi Odoshi fountain to arm the siphon very reliably but it still has one moving part, but that's a story for another day). Quite fun, messy and time-consuming rabbit-hole to go down to, cause you need to get the details right.
