Dexas Ice-ology has come up with a cool—and we mean it—way to create clear ice cubes. And they’re taking a cue from Mother Nature.

Pour water in the mold and pop it into the freezer. It will freeze slowly from the top down, just like in nature. This process pushes out bubbles, cloudiness, and impurities, so you’re left with a clear cube and nothing else. The end result looks stellar and melts slowly (no diluted cocktails here), and some folks think it tastes better, too. Cheers to that.
