## What ice shape lasts the longest?

Rate of heat dissipation is proportional to surface area. A sphere has the smallest surface area to volume. A spherical ice “cube” would stay frozen the longest.

Cubed ice

## Is flake ice good for drinks?

Flake ice is also great for beverage displays or drink tubs, where customers can grab their drinks. Flake ice holds bottles and cans in place and provides even cooling throughout. Flake ice machines produce ice that is light and airy, so ice sticks to itself.
