A 3D-printed Pythagorean (greedy) cup that drains itself completely when filled past a hidden line. The siphon is buried inside the cup wall to make it impossible to spot, which is only possible with 3D printing.

A siphon hidden in the wall
A Pythagorean cup, also called a greedy cup, behaves like any other cup until you fill it past a hidden line, and then it drains itself completely.
I wanted mine to keep its secret, so I buried the siphon inside the cup wall where it is impossible to spot. A section cut through the CAD model shows the narrow channel running up inside the wall. Hiding a channel like that is only possible with 3D printing.
