My take on a Pythagoras cup

thingiverse

This is a personal take on a Pythagoras Cup. Pythagoras cups are also called "Greedy Cups." these cups have a main reservoir like most other glasses, but it also has a "secret" channel running along the inside that leads from inside the reservoir out the bottom of the cup. the story behind these varies but the just of it is that you give this cup "secretly" to someone who might try to fill it all the way to the top and if they do the channel fills up then starts a siphon and takes all the liquid out of the glass.
