Why teapots always drip

The "teapot effect" has been threatening spotless white tablecloths for ages: if a liquid is poured out of a teapot too slowly, then the flow of liquid sometimes does not detach itself from the teapot, finding its way into ...

When you pour cream into a cup of coffee, the viscous liquid seems to lazily disperse throughout the cup. Take a mixing spoon or straw to the cup, though, and the cream and coffee seem to quickly and seamlessly combine into ...

A new understanding of patterns in fluid flow

Scientists have explored, for the first time, the viscous fingering (VF, one of classical interfacial hydrodynamics) of an annular ring, where 'fingers' in a fluid of finite volume grow radially, through a combination of ...
