The use of a column of steadily drained foam as a sample of wet foam is limited by flow instability as the liquid fraction is increased. We report a study of this instability, which takes the form of a convective roll of bubble motion at a value of liquid fraction roughly half that of the wet foam limit at which a static wet foam becomes unstable.
