Spotted in the MAKE Flickr pool, this cool vid from Jessica Rosenkrantz featuring a simple Hele-Shaw cell, which, per Wikipedia, demonstrates “Stokes Flow between two parallel flat plates separated by an infinitesimally small gap.” Further, “[v]arious problems in fluid mechanics can be approximated to Hele-Shaw flows and thus the research of these flows is of importance.”

All of which means very little to me. But I can tell you this: Jessica’s video shore is purty. Give it a watch.
