Pythagorean Cup – The "Greed" Cup

Description

Discover the ancient and entertaining invention of the Pythagorean Cup, also known as the "Greed" Cup. An ingenious model demonstrating a physical principle: when overfilled, the cup empties itself completely through a hidden siphon. Ideal for teaching moderation in an original and memorable way. Some products allow multiple units without increasing the price; please send a message. The price is not negotiable! I only sell in person in the Barreiro area and surroundings. I can ship by mail, but only with advance payment via MBWay, and shipping costs are borne by the buyer. #pythagoreancup #greedcup #siphon #physics #educational #fun #magictrick #experiment #scienceathome #practicality
