Janus microspheres composed of two hemispherical surfaces with distinctly different surface complexities show strongly contrasting water affinities between the two halves. As S.‐H. Kim, S.‐Y. Lee, and S.‐M. Yang describe in their Communication on page 2535 ff., the microspheres were prepared by a simple process that commences with Pickering emulsion droplets. Placing the Janus particles at an air–water interface resulted in the formation of a highly flexible and robust superhydrophobic membrane.
