The Greedy Pythagoras Cup! 🥤 | The Action Lab

This experiment shows how Pythagoras Cup works. A long time ago Pythagoras made this cup (also known as a Greedy Cup), that empties itself if too much drink is poured.

Pythagorean Cup, designed by Pythagoras over 2,500 years ago, still remains a popular practical joke.😁 There is a column in the middle of the cup, which in fact is a twisted pipe connected to the hole in the bottom. If you try to fill the cup over the certain level, Pascal’s principle of communicating vessels causes the liquid to run over the stem inside the column, creating siphon effect and draining the entire cup. The legend says that Pythagoras made this cup to punish friends who poured too

The Pythagoras Cup: Ancient Physics That Punishes Greed The Pythagoras Cup is one of history’s most ingenious inventions—using pure physics to teach moral discipline. Designed over 2,500 years ago, the cup appears ordinary, but pouring beyond a certain level activates a hidden siphon that drains every drop from the cup. Attributed to Pythagoras, this clever design ensured fairness and moderation, especially among students and workers. It stands as a timeless example of how engineering and ethics
