There are plenty of plastic molds to create icd spheres for cocktails. But Wintersmiths Ice Baller takes things up a notch by creating perfect, crystal-clear ice balls for your bourbon and other liquors.
It's made from a silicon mold, wrapped in an outer mold and stainless tumbler, and the directional freezing method pushes the air bubbles outside the ice by the time the water has frozen. Brilliant.
The Ice Baller Kit is currently selling for $85. If you're looking for an ice ball kit that's under $10, try Chillz Ice Ball Maker.
