"Drop star" — a liquid drop, flattened under the influence of some force and which form changes as a result of fluctuations. In other words, it is two-dimensional interpretation of more usual three-dimensional fluctuations. In video it is shown as ultrasonic waves can be applied to a liquid drop raising over a surface, that is its levitations. At the same time due to surface tension the drop is flattened and takes the disk form. Further gradually begin to do "star" of this disk, changing the resonance frequency of a drop. Liquid tension changes depending on different oscillating behaviors which in turn can be regulated the drop radius, properties of liquid and frequency of a sound.

And the person consists of water too. However, only for ±60%. Let's pick up the necessary tonality (that did not break off) and we will depart.
