A method of measuring the dynamic wetting angle between a liquid and a solid surface moving into the liquid as a function of the speed of the solid surface relative to the liquid comprising the steps of moving the solid surface into the liquid at a constant speed, adjusting the angle of the surface entering the liquid until the wetting angle is equal to the angle between the solid surface and the quiescent surface of the surrounding liquid, and measuring said adjusted angle. In another embodiment, the speed of the solid surface entering at a selected angle is adjusted until the meniscus adjacent the surface becomes level, and the speed is measured.
