We describe a microrheological strategy that enables sensitive surface shear rheology measurements of surfactant-laden interfaces, with the capacity to simultaneously visualize deforming interfaces. This technique utilizes a ferromagnetic microbutton

Significance Why some surfactant molecules promote long-living foams, while others are low foamers, remains mysterious. Experiments over the past 60 y have suggested that a surfactant’s surface shear viscosity ( η S ) is correlated with the stabil
