Glacier Rocks Ice Sphere Molds by Viski

Crystal-clear ice spheres chill faster, dilute less and last longer than cubes can. Fill mold with water, freeze for at least 4 hours, and open to release a perfect ice ball - a better way to savor liquor on the rocks. For added flavor and garnish, fill the molds with citrus fruit slices, herbs or use juice in place of water.
