Why Superhydrophobic Materials Never Get Wet [Science Video]

Raincoats, car windshields, waterproof phones: They all use a little chemistry to stay dry. Inspired by nature, chemists use extremely water-fearing, or superhydrophobic, coatings to repel water from surfaces to keep them dry. Watch as the Reactions team uses a high-speed camera and some brave volunteers to bring the science of staying dry to life. […]
