= Liquid marbles
{wiki=Liquid_marbles}
Liquid marbles are small droplets of liquid that are encapsulated in a hydrophobic (water-repelling) solid coating, which prevents the liquid from wetting the surface and allows it to behave like a small, discrete marble. This phenomenon is achieved by the process of coating the liquid droplet with a layer of solid particles such as hydrophobic powders (like hydrophobic silica, starch, or polymer beads), which cling to the droplet's surface.
