Ultraslippery Surface Construction. Click image for more info.

Researchers create the ultraslippery coating by creating a glass honeycomb-like structure with craters (left), coating it with a Teflon-like chemical (purple) that binds to the honeycomb cells to form a stable liquid film. That film repels droplets of both water and oily liquids (right). Because it’s a liquid, it flows, which helps the coating repair itself when damaged.
