Reflective and Scattering Surfaces

Caption

Researchers have developed a way to dynamically switch the surface of liquid metal between reflective (top left and bottom right) and scattering states (top right and bottom left). When electricity is applied, a reversible chemical reaction oxidizes the liquid metal, creating scratches that make the metal scattering.
