Colloidal dispersions dried in thin capillaries exhibit a fascinating array of cracks. Researchers in this Hot Article present experiments where the cracks are preceded by delamination in which the particle packed region debonds from the walls of the capillary before cracking. Their results highlight the importance of substrate deflection in describing the dynamics of drying.
