Vibrating their substrate is an efficient way to manipulate drops and even to sculpt them, as recently discussed in the literature: (1) drops on a shaken inclined plate can surprisingly climb the slope [1]; (2) a puddle on a horizontal vibrating material deforms with asymmetric shapes [2]; (3) an impulsive motion of the substrate generates superpropulsion, that is, an enhanced takeoff of the deposited liquid [3]. Here we report the striking shapes obtained when subjecting water pearls to a strong, quick, vertical impulse.
