My dog eats and drinks out of metal bowls. I’ve noticed that when I turn around after filling up the water bowl in the sink, any spit bubbles or backwash on the surface of the water stay oriented the same way (relative to everything else, not me). Why is this? This behavior doesn’t change regardless of how fast or slow, careful or not I am. I’m not sure what kind of metal the bowl is, but it’s about the size and shape of half a basketball. Where I live, the tap water is pretty damn clean. If there are any extraneous factors I haven’t thought to mention, let me know.
I’m not a scientist but no.
Stuff on top of water will necessarily move alongside the water underneath it.
The solution lies in the viscosity of the water itself, being low enough that the motion of the molecules in touch with the rotatin bowl don’t transfer enough force to the inner “layers” of water to offset its inertia.
ELI5: water be a slippery fuck, too heavy to spin at your whims.
