Roll Formation in Shampoo Vibrated...

Posted at 7:06 PM • 25 Comments

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.

When an object with …
When an object with a sustainable shape that is predictable and observable while at the same time is unequal to that of an perturbed identical object, it creates a new relationship or law based on the relative perturbation frequency.

I think that is a phase transition? The hotter something gets the higher perturbation frequency and thus a different predictable and observable form.

Just like if you made the shampoo hot, this would work better while making it colder would be worse.

Huh? I can ure you that “planetary gravity” has not been destroyed in this experiment. The plate is launching sound waves into a thin layer of shampoo, the viscosity of which decreases with shear rate. I am fairly certain this behavior can be explained by the resultant viscosity profile.

does anyone find it interesting that with with vibration comes predictable conglomeration, but in space the only thing to group objects is gravity?

I see this as an example of how, in certain situations, outside of the quantum world you can have scenarios where angular momentum or vibration frequency destroys planetary gravity and creates its own microgravity… very interesting.

I wonder what shape it would take it you vibrated it with a speaker in the iss.. a pulsing sphere like the sun?
