Resonance is a phenomenon that embodies itself in various areas of physics including fluid dynamics. The characteristic frequency at which a levitated liquid droplet can be made to resonate is intimately related to practically important physical quantities such as density and surface tension. In this video submission, electrostatically levitated molten Zr and water droplets are made to oscillate wildly at different frequencies--resulting in beautiful spherical patterns and a direct visualization of resonance.
