We're sure there's a lot of science involved, but we're not going to bore you. Perfect spheres of ice melt at a slower rate than their traditional cube cousins. Investing in a few stackable Tovolo Sphere Ice Molds ($11) means you'll only need one sphere per drink, cutting down on your water usage and the number of times you have to refill those damn ice trays. Come summer, we bet you could also freeze fruit and herbs inside the spheres for gorgeous drink presentations.
