Since Harold Edgerton's seminal work in the 1930s, which captured the intrinsic complexity of a drop impacting a liquid bath, much work has been devoted to studying drop impact on liquid pools, thin films, or dry surfaces. Yet, the successive impacts of liquid droplets at different locations on a substrate can lead to different scenarios where the droplet may impact a surface dry, wet, or partially wet and partially dry. In this video, we illustrate how, in such a scenario, the droplet can splash on the dry surface, exhibiting a film of a few hundred microns and creating waves propagating across the liquid film. Microdroplets are also generated at the edge of the corolla and carried away by the splash. This situation represents a delicate and ephemerous balance of coalescence spreading and splashing.
