The problem you face is this: water is a homogeneous collection of one type of molecule. Milk is a heterogeneous collection of hundreds of different molecules, some of them quite large. Now, any given molecule, if in a homogeneous assembly, has a measurable partial pressure, which defines (roughly) the evaporation rate. However, once you mix molecules, ...

In my experience, in brushes the strongest force acting on the water is the capillary force due to the surface tension in the liquid and the proximity of the hairs in the brush. Surface tension will cause the water to try to "wet" as much of the brush hair as possible - regardless of orientation. If there is excess water, such water will be pulled down by ...

You should let it hang downwards, otherwise the water will drip down onto the ferrule, which can eventually corrode it. There's pretty much no reason to leave them tip-up: in particular any "local pocket" of humid air is unlikely to be rising much rather than expanding outwards in all directions. If you are worried about the local pocket of humid air during ...
