Inspired by water-strider legs, a new design of a robust superhydrophobic surface is developed. It is successfully achieved on a copper surface and consists of copper hydroxide nanoneedle arrays sculptured with nanogrooves. Squeezing and relaxing water drops between two such surfaces leads to a fully reversible exploration of the solid surface by the liquid.
