Super Waterproof Surfaces

Artificial waterproofing — which includes physical and chemical barriers to water — keeps the rain off our clothes, our tents dry, and protects our watches when we jump into the pool. But it also occurs in nature: Lotus leaves keep clean with super-waterproof surfaces that repel moisture.

Scientists now create similar surfaces in the lab. Investigate the past, present, and future of waterproofing.
