A Handy Device That Uses Ambient Heat and Gravity To Make Ice Spheres That Melt Slowly In Drinks

The Ice Ball Mold is a handy device that uses only the ambient heat discharged from a conductive metal (such as aluminum or copper) and the weight of the metal itself to transform an ice cube into a slow-melting sphere that looks pretty cool in cocktails. The excellent bartenders at The Shanty in Brooklyn, New York have been known to use one of these on a slow night.
