Leaping shampoo and the stable Kaye effect

The 'Leaping Shampoo' video reveals the underlying physical mechanisms of the so-called Kaye effect. The spectacular effect is a classic textbook example to illustrate the rich dynamics of complex fluids and was first described by A. Kaye in a 1963 Nature paper, however, no published discussion or explanation for this phenomenon existed until now. In the video the Kaye effect is now explained, also for more common fluids, such as shampoo and liquid hand soap, through the shear-thinning properties of the fluid. The classical Kaye effect is extended to a stable, even to a cascading configuration. Gallery of Fluid Motion Award-winning entry 2006
