Pythagorean Goblet

My goal was to make a version of the pythagorean cup that:looks like a real (mediaeval or so) goblet hides the siphon mechanism inside the walls of the cupdrains the water very quickly after reaching the “magical line” How to get the best resultsPlace the goblet on a level surface. Gently fill in the water, otherwise it might splash up the tubes in the siphon and cause it to run even-though the water level is still beneath the line.I'd recommend using a hydrophobic polymer (for example PLA) for this print, so the water does not get “stuck” in the tubes after emptying. How this worksThe main principle behind this is the siphon. It allows a liquid to flow upwards a bit without being actively pumped up. But since the laws of thermodynamics (sadly) also apply to the siphon, the liquid doesn't just flow up on its own. The tube trough wich the water flows must end at a point where the liquid has a lower gravitational potential, meaning, if you look on the syphon as a whole, the liqui
