“We are interested in designing surfaces that can promote condensation of water, which has important heat-transfer and water-harvesting applications,” says Marcus Lin, a research fellow in the lab of Dan Daniel, who led the research. On a typical solid surface, condensed droplets stick to the surface with minimal motion. “Think of water condensing on a cold soda can,” says Lin. “The droplets only move once they grow big enough for gravity to pull them down.

Once the local oil rebuilds, the snake-like dance resumes.
