An experimental study has been done on the flow of viscoelastic liquids squeezed between two flat parallel plates. In fast squeezes under a constant load, the plates did not come together as rapidly as predicted by inelastic fluid theory. Our experimental data suggest that this device is not generally useful as a viscometer.
