Scientists have created the effect of fluid levitation using sound
A “drop-star” is a drop of liquid, flattened under the influence of a certain force, and the shape of which changes under the influence of vibrations. In other words, this is a two-dimensional interpretation of more familiar three-dimensional vibrations. The video demonstrates how ultrasonic waves can be used to lift a drop of liquid above the surface, that is, its levitation. At the same time, due to the surface tension, the drop flattens and takes the form of a disk. Further, from this disk gradually begin to make a "star", changing the resonant frequency of the drop. The surface tension of a fluid varies depending on the different modes of oscillation, which in turn can be adjusted by the radius of the drop, the properties of the fluid, and the frequency of the sound.
But man also consists of water. True, only ± 60%. We select the desired tone (so as not to break) and fly.
