Dancing Mercury

A drop of mercury being vibrated from ~120Hz down to ~10hz filmed at regular speed. The high density and surface tension cause it to resonate at different frequencies in different ways. The higher the frequency the more nodes it will form on its edge. - YT

How stable are the nodes if you keep it at one of the resonant frequencies that made the "starfish" type patterns? It looked to me like it would create a revolving wave around the circumference that would be stable, but it would be really cool if it would stay like that without revolving at some particular frequency.
