Summary

This is a modern interpretation of pythagoras cup. The self emptying cup. With the help of 3D printers, it is now possible to place the tube in the wall of cup instead of a tower in the middle.

Magic? No, just physics. The tube inside the body creates a siphon. This siphon will empty the cup when it is overfilled.
