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]
