WHAT does a drop of water have in common with a black hole and an atom? Well, levitating water droplets can now simulate the dynamics of both cosmological and subatomic objects. Richard Hill and Laurence Eaves at the University of Nottingham, UK, turned to water droplets because the surface tension that holds the drops together can be used to model other forces. For example,
