Paper marbling in rotation

Paper marbling is an ancient art form that has evolved over centuries across various cultures, traditionally used for bookbinding and decoration. Building on our previous work investigating the roles of interfacial tension and viscosity in marbling (DOI: 10.1103/PhysRevFluids.9.110506), we extend our study to a rotating frame. We perform a series of marbling experiments on a rotating table, varying the viscosity of the bath and the rotation rate to examine how Coriolis forces and viscous effects influence pattern formation. By introducing rotation, we connect the aesthetics of marbling with physical processes found in geophysical and atmospheric flows. The resulting patterns exhibit striking analogies to large-scale vortical structures observed on planetary surfaces, offering a visual bridge between art on a tabletop and fluid dynamics on a planet.
