The superhydrophobic glass shares some properties with the super-waterproof fabric coatingwe learned about this week, and it, too, is a feat of nano-engineering. But instead of a waterproof coating, it earns its special properties through a special etching process. Kyoo-Chul Park, Hyungryul Choi and colleagues drew inspiration from nature, including zebra plants, which contain conical structures that repel water. They developed a method to embed an array of steeply angled cones on the surface of glass.
