This great story, like many others, starts in a whiskey bar in Japan. Caesar ordered a 12-year-old Macallan scotch on the rocks—and was served his beverage in a rocks glass with a giant ball of ice, made with a $2000 copper machine that turns a block of ice into a sphere. The ball shape minimizes the surface area exposed to air, thus it melts slower. That mean—now stay with us here—that the ball chills a drink for longer without watering it down. Foiled again by the Japanese, he set about making a cheaper alternative to this genius ice ball, landing on an ultra durable mold made of silicone rubber. See, it pays to go to the next whiskey bar.
