ABSTRACT	The application of an AC electric field to a mercury drop resulted in large-amplitude shape oscillations due to variations in its surface tension.Quasi two-dimensional (2-D) oscillation patterns were identified from the 2nd-16th modes for flattened drops under a pressure of 1G.In addition,three-dimensional oscillations were observed in low-gravity using a drop tower,with several polyhedra patterns being clearly identified,e.g.,a tetrahedron,hexahedron,octahedron and dodecahedron.
