The Kaye Effect

I found this very interesting video that demonstrates the Kaye effect using a high speed camera and a bottle of shampoo.

The Kaye effect was first described by the British engineer Alan Kaye in 1963. Hence the name. The best description I could find, was from the rather sparse wikipedia article on it.

“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 down going one.” Wikipedia: Kaye effect

It’s a pretty cool effect, and one that we have all probably seen before, but just didn’t really notice because it happens so fast.
