Leaping Shampoo and the Kaye Effect

Researchers at the University of Twente in The Netherlands won a prestigious place in the ‘Hall of Fame’ of videos about fluid-in-motion. They have made a video of leaping shampoo, in which they explain the so-called Kaye effect. Scientifically interesting but also of great aesthetic beauty!

The Kaye Effect is a strange property of complex liquids which was first described by the British engineer Arthur Kaye in 1963. While pouring one viscous mixture of an organic liquid onto a surface, the surface suddenly spouted an upcoming jet of liquid which merged with the downgoing one.This phenomenon has since been discovered to be common in all thixotropic liquids (liquids which thin under shear stress).
