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