A deformation of the interface between convectively stable, unstable layers in a star can lead to intensified mixing of the elements. Our three-dimensional simulations show that under a condition of deformability of the interface, a coupled long-lived system of large-scale flows, penetrative convection is established. This effect can explain lithium depletion in the solar atmosphere
