"Ice cubes are so passé. We’ve already seen them challenged in their drink cooling duties by Sippin’ Rocks and now there's a new threat looming. The Ice Ball Mold transforms an irregular shaped chunk of ice into an icy sphere, which its proponents say are more desirable than cubes because they melt more slowly due to their smaller surface area - thereby keeping your drink cooler and less diluted for longer." - Kurt Starnes
