+ - Control water with electricity

MattSparkes writes: "French researchers have discovered a new way to create super-hydrophobic surfaces, which could make completely electronic control of water possible. This could replace messy pumps and valves. By passing a voltage across a water droplet on the surface, it's shape can be deformed, and when the voltage is removed, it springs back into shape. Although the distortion is small, it should be enough to push droplets around by controlling the voltage between many different surface electrodes."

Don't panic.
