A floating droplet on a liquid substrate can oscillate when the surface temperature is spatially modulated. The droplet shape and motion become locked to the modulation period.

When two cavitation bubbles form near a particle in sequence, their collapse is no longer independent. The second bubble reshapes the jet from the first, creating regimes of deflection, amplification or damping depending on timing.
