APS tip sheet: Understanding the tears of wine

March 10, 2020

Sometimes in a glass of wine, liquid can appear to climb the side of the glass, forming "tears" that slide back down into the wine. Now, researchers have created a new hydrodynamic model to better account for wine tears' fluid dynamics. The model shows that a combination of fluid physics, including gravity, surface tension, and changes in surface tension induced by alcohol evaporation, can lead to complex fluid structures resulting in wine tears.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
