A sand drop, instead of a water drop, is used to show the effects of liquid hitting a liquid surface; which, in this case, is a sand drop hitting the hard surface of sand, but showing the after effects, or ripples, normally seen on a liquid surface. In physics, this is known as a 'Conformal Anomaly', which is an anomaly i.e. a quantum phenomenon (sand) that breaks the conformal symmetry of the classical theory (ripples).
