The Falling Droplet device was used to measure the extensional viscosity of a variety of aqueous polymer solutions. These solutions were atomized with the miniature "inverse" twin-fluid atomizer. Droplet size measurements were made with a Malvern laser diffraction particle sizing device. Droplet sizes measured did not rank strictly according to either lowshear rate shear viscosity or extensional viscosity.
