The Kaye effect - Leaping Shampoo

[PlasmaSphere]

What do think is going on here? leaping shampoo ?

The tube of liquid seems to enter the liquid, turn around 180 degrees just below the surface, and stream back out the way it came in.

Observations:

* A heap is formed

* A streamer ejects

* the ongoing jet rises

* hits the incoming jet

* this ends the kaye effect

total time: 300 ms.

I'm thinking along the lines of surface tension, or EM forces, but i don't know how it would actually work.

Oh and i found that video from here; Top Ten Laboratory Reactions, which is worth a look aswell.

That's cool. And yet, fluid/continuum mechanics is not part of the tradiational physics canon in school.

Because it's a stable jet, there is definitely competition between viscous and surface forces (Bond number, capillary number, probably some others). But fundamentally it's due to the nonlinear nature of the flow. I should read their referenced paper...

I checked out that link at the bottom, and earlier today I did the experiment with the instant freezing water, I just thought I'de let you guys know that:
1) It works
2) Its really cool to watch.

BTW: The superheating trick uses pretty much the same concept as the supercooling, however, I'm not brave enough for that.
