半径为毫米的液体壳在超声场中被声学悬浮。在壳上观察到毛细波。在低能量（最小声振幅，厚壳）下，在对称和反对称薄膜振荡模式之间观察到共振。在高能量（高声压，薄壳）下，壳被高振幅波完全覆盖。在这种状态下，来自壳层的散射光的时间光谱表现出指示湍流的幂律衰减。
Millimeter-radius liquid shells are acoustically levitated in an ultrasonic field. Capillary waves are observed on the shells. At low energies (minimal acoustic amplitude, thick shell) a resonance is observed between the symmetric and antisymmetric thin film oscillation modes. At high energies (high acoustic pressure, thin shell) the shell becomes fully covered with high-amplitude waves. Temporal spectra of scattered light from the shell in this regime exhibit a power-law decay indicative of turbulence.
