Eternal Ice Drop Makes for a Perfect Cognac

On-the-rocks drinkers can be very particular about their ice. Creating perfect ice spheres is one way to ensure that you don't sacrifice flavor—this Ice Drop is another.

Created by the team at 5.5 designers for Hennessey cognac, the Eternal Ice Drop is basically a spherical piece of glass with frozen water inside. The spherical shape takes up less surface area, the ice doesn't melt into the drink, and it chills at a rate that will give you plenty of time before severe cold masks the flavor. I'm not sure how this will do a better job than other artificial ice cube designs, but I am sure the Ice Drop will be far more expensive when it is released this April. [5.5 Designers via Designboom]
