Researchers have succeeded in clearly identifying why droplets on soft, squishy surfaces react differently than on hard surfaces. A water droplet, for example, moves very differently over jelly than over glass, but the science of how this works has never been investigated. Better understanding of this phenomenon is of importance for a variety of applications where droplets come into contact with extremely soft, deformable materials, as is the case in 3D printing, soft contact lenses or sauces such as mayonnaise.
