Harry,
I believe it is very thin liquid that happens to border two
systems of different pressures. In fact, I just read a report in the APS
News "paper" about a talk at the Spring APS meeting in Columbus where a
professor was using bubles to run experiments in 2-D hydrodynamics. I can
dig it up for more details if you wish.
