  Pressure-driven coarsening triggers bubble rearrangements in liquid foams.
Our experiments show that changing the continuous phase rheology can alter
these internal bubble dynamics without influencing the coarsening kinetics.
Through bubble tracking, we find that increasing the matrix yield stress
permits bubble growth without stress relaxation via neighbor-switching events,
promoting more spatially homogeneous rearrangements and decoupling bubble
growth from dynamics. This eventually leads to a structural change which
directly impacts the foam mechanical and stability properties, essential for
applications in various technological and industrial contexts.
