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… Expand
Leaping shampoo glides on a lubricating air layer.
It is shown unambiguously that the jet slides on a lubricating air layer, identified by looking through the pool liquid and observing its rupture into fine bubbles, which suggests this air layer is of submicron thickness. Expand

Abstract The Kaye effect is a phenomenon whereby a jet of fluid poured onto a surface appears to leap on impact, rather than stagnate or coil as expected. Since it was first described in 1963,Expand
The Kaye effect
The International Young Physicists' Tournament (IYPT) is a worldwide, annual competition for secondary school students. This is our solution to problem number 10, The Kaye effect, as presented in theExpand
The Kaye Effect
The Kaye Effect is a phenomenon which was first described by Alan Kaye in 1963.When a thin stream of shear-thinning fluid is poured onto a flat surface we can observe the stream ocasionally leap outExpand
Bouncing jet: a Newtonian liquid rebounding off a free surface.
It is found that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet, and the bouncing phenomenon exhibits hysteresis and multiple steady states. Expand
Stable Liquid Jets Bouncing off Soft Gels.
A liquid jet can stably bounce off a sufficiently soft gel by following the contour of the dimple created upon impact. This new phenomenon is insensitive to the wetting properties of the gels and wasExpand
New Experiments on the Kaye Effect
When a jet of a thinning fluid is poured over a perpendicular surface covered with the same fluid, under certain circumstances it is observed that a small jet seems to bounce out of the surface veryExpand
Numerical simulations of bouncing jets
Bouncing jets are fascinating phenomenons occurring under certain conditions when a jet impinges on a free surface. This e ect is observed when the fluid is Newtonian and the jet falls in a bathExpand
Instabilities of jets of non-Newtonian fluids impacting a plate
The problem of buckling and coiling of jets of viscous, Newtonian liquids impacting a plate has received a substantial level of attention over the past two decades, both from experimental andExpand
Nonlinear Dynamics of Coiling in Viscoelastic Jets
for many industrial processes, remain less well understood in terms of fundamental fluid dynamics. Inviscid, and viscous Newtonian jets have been studied in great de- tail; buckling instability inExpand


The Kaye effect revisited
WHEN a thin stream of certain solutions of polyisobutylene in dekalin is poured on to an open evaporating dish, a heap of the liquid forms at the point of contact with the dish. As pouring proceeds aExpand
Rheology of non-Newtonian fluids: A new flow equation for pseudoplastic systems
On the assumption that pseudoplastic flow is associated with the formation and rupture of structural linkages a new flow equation is derived. The equation takes the form ƞ = ƞ∞ + ƞ0 − ƞ∞1 + αD23, Expand
Measurement of wall-slip-layer rheology in shear-thickening wormy micelle solutions
A microscope-mounted torsional shearing-flow cell is constructed and microscopic particle imaging velocimetry is employed to directly visualize and map the velocity slip layer in a shearing flow ofExpand
Fluid ‘rope trick’ investigated
Buckling instabilities can arise from competition between axial compression and bending in slender objects. These are not restricted to solids, but also occur with fluids with free surfaces,, inExpand
