Pythagoras is known to most students today as the author of the Pythagorean Theorem (a²+ b² = c²). However, there was far more to Pythagoras' philosophy than this: he was a deep thinker on religion, the nature of the soul, and the harmony of the cosmos. With the "Pythagorean Cup" he illustrated to his students the virtues of moderation: when filled halfway, it retains its contents, but if it's too full, all of the liquid drains out through a hole in the bottom.
Our Pythagorean cup is manufactured of clear glass and hand blown. The secret of the construction is the siphon, which is built into the center of the cup. This fun and functional product is an ideal way to explain the principles of a siphon to your students while including an historical background. Height: 250 mm Cup: 80 mm Ø
