We showcase the numerical simulations of a vibration-induced drop atomisation in zero gravity. Vibrations at high amplitude and frequency lead to nonlinear wave interactions. The chaotic superposition of these waves leads to craters' formation of negative curvature that creates localized jets. These complex jets and craters resemble the hair of the Greek goddess, Medusa, hence called, the Drop Medusa. We invite the viewer to observe drop bursting at different angles to observe the analogies to numerous classical fluid-dynamical configurations: Rayleigh capillary pinch-off, Worthington jet formation and breakup.
