A method and apparatus for reducing friction at the interface between a liquid and a solid. A solid interface member includes a plurality of apertures over the entire surface which are to be in contact with the liquid. The apertures are of a size and dimension such that the surface tension of the liquid will not allow the liquid to pass through the apertures, but which will allow a gaseous material with less surface tension than the liquid to pass therethrough. The gaseous material is thereafter motivated through the apertures to interpose a gaseous layer at the liquid solid interface which reduces the drag coefficient therebetween, which would otherwise result from relative motion between the solid interface member and the liquid.
