The shape, beauty, and simplicity of the sphere has captivated humanity for centuries. When Archimedes first wrote the equations for the surface area and volume of a sphere he defined the most perfect shape imaginable.The sphere even shattered religious and scientific paradigms when the shape of our planet was audaciously argued to be round.
Spheres happen to be a thermodynamically superior shape for ice. Its low surface area to volume ratio ensures that your drink will be perfectly chilled. Water will form slowly in your glass allowing you more time to enjoy your beverage. Rigorous heat transfer calculations and numerous taste tests reveal that a 2.4" diameter sphere is the ideal amount of ice for most drinks served on the rocks.
