Experiments on surface tension driven flow in nominally cylindrical columns of a glass melt and silicone oils are described and results are presented. Predictions from an appropriate theoretical model are included. Conclusive proof has been obtained for the dominance of surface tension driven flow in these systems under the conditions of the present investigation.
