000015456 520__ $$2eng$$aWe demonstrate the instability of the free surface of a soft elastic layer facing downwards. Experiments are carried out using a system consisting in a gel of constant density p and shear modulus u, put in a rigid cylindrical dish of depth h. When turned upside down, the free surface of the gel undergoes a normal outgoing acceleration g. It remains perfectly flat for pgh/u < 04* with 04* 2 6, whereas a steady pattern spontaneously appears in the opposite case. This phenomenon results from the interplay between the gravitational energy and the elastic energy of deformation of the system.
