Creation of a levitating liquid layers

Making two liquid layer levitate. The liquid is silicon oil, the forcing frequency is 100 Hz. The forcing amplitude is tuned during the process to control the size of the liquid layers. The container has a horizontal section of 5×4 cm2. See article for details: Apffel, B., Novkoski, F., Eddi, A. et al. Floating under a levitating liquid. Nature 585, 48–52 (2020).
