I was thinking the same - if there was an upward force then fluids would be spraying all over the place!!!

And the shape of raindrops.

Okay.
Added, gel like substance which normally behaves like a liquid but when agitated takes on the properties of a solid. Thus can connect two moving parts ie engine and gearbox.

The earth's mantle behaves in much the same way, over longer timescales. Seem to remember something about Young's strain modulus. :chinrub:

Yes correct, that was a general query on fluid dynamics and not surface tension related.

Oi Social Service Lane
Where in that little extract does it say anything about the liquid pushing upwards? The liquid just sits there and is displaced by something of lower relative density.
Anyway, speaking of non-Newtonian fluids, custard MMmmmmmm
