Wet, wet, wet : Typical wetting transition (from spreading to bouncing) of water droplets on micro‐ and nanostructured surfaces at high temperatures has been investigated. The spreading and bouncing behavior varies on substrates with different wettabilities (see picture; substrate brown, water droplet blue, water vapor white), and the bouncing temperature changes when the microstructure of the surface changes.
