Diverse Transformations of Liquid Metals Between Different Morphologies

Transformation from a film into a sphere, rapid merging of separate objects, controlled self-rotation, and planar locomotion are the very unusual phenomena observed in liquid metals under application of an electric field to a liquid metal immersed in or sprayed with water. A mechanism for these effects is suggested and potential applications – for example the recovery of liquid metal previously injected into the body for therapeutic purposes – are outlined.
