Thinning shears are a tool that can be used to blend transitional lines and thin out bulky spots on a dog’s coat, and they should be used with a dog restrained. Give a dog a smooth coat and avoid ripping her hair out with help from a professional dog groomer in this free video on using thinning shears on dogs.

Shampoo, a shear thinning fluid, is vibrated at several frequencies. Above a critical oscillation amplitude, rolls form. The fluid flow is similar to two adjacent Rayleigh-Bernard convection cells with the left one rotating CW and the right one CCW. This video documents the behavior and formation of these rolls.
Note: Apparently youtube doesn’t let you upload copyrighted music…ignore the bit at the end.

A layer of shampoo is vibrated in a petri dish at 60Hz. Depending on the oscillation amplitude, several phenomena are observed. Most interesting, is the formation of a stable rolling column, documented in this video. Column is made from two adjacent rolls, with fluid flowing down the center of the column and up at the edges. Circular flow cells can be formed if the column is not in contact with the dish’s walls.
I built this apparatus to investigate the vibration of shear-thickening particulate suspensions (high-mass fraction cornstarch solutions) but decided to try out shampoo because it was a shear thinning fluid. I think the explanation lies in the shampoo’s high-viscosity and shear-thinning property. I just observed this for the first time minutes ago, and haven’t come up with any explanation yet. Also, the shampoo gets opaque after vibration – I think it may even be forming a very soft foam.

www.FreeScienceLectures.com 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. A. Kaye in Nature magazine in 1963 wrote “I can offer no explanation for this behaviour.” At high-speed recording of 1000 frames per second the following observations were made in 300ms interval 1) a heap is formed, 2) a streamer ejects, 3 …
