Whiskey on the rocks? How about whiskey in the rock—or rather the iceberg. Take whatever you're drinking down to arctic temperatures with this 2-way iceberg ice mold kit. The silicone mold sits upside-down in the square Old Fashioned glass provided, to be filled with water both inside and outside of the mold. Once frozen, the mold can be pulled from the glass, resulting in both an iceberg-shaped ice cube (for another glass) and an ice-lined Old Fashioned glass, for serving two ounces of very cold spirits.
