What's this called when panel lining?

[Bobby]

So I was helping a friend's son with some panel lining tips and couldn't think of the actual term to describe the behavior of the pigment when it moves itself along the panel lines.

Does anyone know the technical word to describe how the liquid pigment just moves itself up down along these tiny channels even against gravity?

I'm guessing it is either some sort of liquid capillary action or surface adhesion? Just figured someone here might be in a field that deals with these kind of fluid dynamics.

I think you got it - "capillary action".

'Capillary Action' is, indeed, the term

[Bobby]

Cool, thanks!

What you called it is much better... "liquid pigment that just moves itself"

[Froy]

Just model builders "mumbo jumbo"

[Bobby]

Well, I did think capillary action sounded so "basement level biology lab" instead of "hobby man-cave" lingo...

How 'bout...
