Splashing is the process by which a solid intruding into a liquid at sufficiently high speed produces a jet of the fluid in its wake, as well as a significant sound. This jet and the associated sound arise from the fluid collapsing around a pocket of entrained air, in the wake of the solid intruder: the closure time is given by <math>\sim(a/g)^{1/2}</math>, where <math>a</math> is the size of the intruder and g is gravitational acceleration. Recent work has demonstrated that splashing can be affected by inertial effects, addition of polymer, vacuum and ambient air conditions, and the wetting properties of the solid intruder.
