I've noticed the zig zag in the synthetics too. On top of the natural hairs being hollow, many natural hairs also have a belly (badger, sable, etc.) The belly keeps the hairs apart below it allowing the brush to hold water or paint. I'm truly amazed at how well people were able to make synthetic fibers mimic this property, albeit by a different method. And yes, I've had water run down my arm when pressing an over wet synthetic to my face. I always figure that that was user error and try not to have too much water in the brush. It's kind of funny that when one of the problems with the non absorbent fibers shows itself it is because the brush is carrying too much water.

Synthetic knots don't absorb water. The water is trapped between bristles and don't let go unless you either shake, squeeze, or splay the knot...
Don't mind me, small details. My "difference", was about "absorbtion" (i intend it as pulling water inside the fibers) and about "capillary action" (as far as i remember from school, capillary action involves movement of liquid inside a tube. Surface tension is different, it's more static, it's a force that allows water to stay in one place, like "trapped").
That is exactly what works best for me with the soap which
currently occupies my bowl. After that soap has been used up
I am going to try a puck of Williams and see how that goes.
