Leaping Shampoo and the Stable Kaye Effect

By Chris V. Thangham     Apr 2, 2007 in Entertainment
Watch the incredible leaping shampoo called Kaye Effect, when a shampoo is poured from a certain height to a flat surface.
Scientists of 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!
When a thin stream of shampoo is poured from a certain height (here 20 cm), as the shampoo is collected at the bottom creates an odd behavior called the Kaye Effect. It is describes as follows from Wikipedia:
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.
You see the same behavior of the shampoo in the video, which was recorded by a high speed video camera at 1000 frames per second. First the shampoo collects at the bottom, a small heap, and then suddenly a stream of shampoo ejects and then this outgoing jet rises to a greater height . This then interacts with the top shampoo that is pouring as a result collapses. This cycle is called the "Kaye Effect". And another cycle repeats similar to this phenomenon.
Even the discoverer of this effect, Arthur Kaye, had no plausible explanation for this behavior but scientists have figured it out and are explaining at the end of the video. I am not good at physics to explain that behavior but to just watch it makes it real interesting.
Just don't waste too much shampoo trying to imitate this "Kaye Effect" and don't show this to your kids :)
