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 flavour - 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 flavour. 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 coming April.
