We exploit the controlled drying of millimeter-sized gel beads to investigate the isotropic compression of colloidal fractal gels. Using a custom dynamic light scattering setup, we demonstrate that stresses imposed by drying on the bead surface propagate homogeneously throughout the gel volume, indu…
