Why Do Coffee Cups Leave Rings. An international research team, led by monash university, has discovered for the first time the mystery behind the formation of ‘coffee rings’ by examining the contact angle of droplets onto a surface, and how they dry. Why does spilled coffee leave a ringlike stain after it dries? Mean­while, oth­er liq­uids are made up of oblong. Dreamstime) coffee stains may seem mundane, but they are. Coffee ring stains are caused by a peculiar quirk of everyday physics.(image credit: Cof­fee is made up of spher­i­cal par­ti­cles, and they get dis­trib­uted uneven­ly, with some push­ing out­ward towards an edge and form­ing dark rings. Researchers say it has to do with the shape of particles in the liquid. Why do coffee stains dry to leave a ring? Why do drops of coffee dry as a clear blob with a dark ring around the edge? But the appearance of these stains is simply a result of the physics happening inside the drop. The researchers spill the beans in tomorrow's. After boggling a team of physicists, this conundrum has finally been solved. Coffee is made of tiny granules of ground up. Scientists from the university of pennsylvania have discovered how coffee spills evaporate to.
