Cruel Coral Pythagorean Trick Cup, 3D Printed Novelty Vessel

This cup has a secret. Cruel Coral looks like a striking little coral flower vessel, with a fluted petal rim and deep ribs running down to a narrow base in a bold red finish. Fill it like any ordinary cup and it behaves, right up until you cross a hidden line inside.

Cross that line and the whole thing drains itself instantly, a 3D printed twist on the ancient Pythagorean cup once used to teach a lesson about greed.

• Coral flower shaped trick cup with fluted rim
• Hidden siphon empties the cup past the limit
• Based on the classic Pythagorean cup principle
• Great party game for groups
• Compact size for a desk or shelf

Printed in PETG Basic and finished raw for a soft matte texture that copes well with repeated filling and draining. Printed to order and shipped from right here in Australia.
