A thin stream of shampoo is poured from a height of 20 cm and recorded with a video camera. This is known as the Kaye effect. I can offer no explanation for this behavior. A high-speed recording of the Kaye effect at 1000 frames per second.
– a heap is formed
– a streamer ejects
– the outgoing jet rises
– hits the incoming jet
– ends the Kaye effect
total time 300 ms
What causes the Kaye effect?
A detailed look
Streamer ejects through shear-thinning property of the fluid.
A dimple is formed in the viscous heap.
Outgoing jet is thicker quantitatively following continuity.
Dimple deepens through a vertical force acting on the viscous heap and the jet rises.
We set up a simple energy balance model.
It includes viscous dissipation and the shear-thinning behavior of the shampoo in the dimple structure.
Elastic properties of the fluid play no role.
The model predicts the leap height of the shampoo as a function of the release height.
It even predicts a critical release height as observed in experiment.
For details see JSTAT / 2006 / P07007
To prevent the outgoing jet from interfering with the incoming jet the surface was tilted.
leading to a stable Kaye effect cascade.
leaping shampoo may even act as a light guide for laser beams in a multitude of colors.
