In physics, a "coffee ring" is a pattern left by a puddle of particle-laden liquid after it evaporates.
The phenomenon is named for the characteristic ring-like deposit along the perimeter of a spill of coffee.
It is also commonly seen after spilling red wine. The mechanism behind the formation of these and similar
rings is known as the coffee ring effect or in some instances, the coffee stain effect, or simply ring stain.

Hello, reader, I am very happy to have you. I'm Rodion/Anatoly. This website is used to indulge in my
long ramblings about everything and nothing all at once. Currently I'm a library technician who resembles that of
a neurotic horse. I have two snake plants named Demeter and Dmitri, and a small euphorbia decaryi named
Persephone (photos of them will go here eventually). I like mangoes, coffee, sinking into deep thought, theory of
any kind, postage stamps, letterlocking, and far more.
