Elliptical Orbit Mugs

£22.43


When liquid is tilted in a cylindrical cup, the top edge of the liquid becomes an ellipse shape - becoming more eccentric (stretched out) as you tip the cup further.

These unique mugs capture the exact elliptical shapes of the orbits of planets and comets in our solar system, by showing the line of each on the outside of the mug. Drink elliptical orbits!

The mugs also include a line showing an ellipse with eccentricity e = 0.5, and a 45° slope. Available in red and blue. 280ml capacity. Not dishwasher safe.

From designer Robert Darwen, who also makes the Fibonacci Spiral Clock and Hyperbola Clock.
