A new experimental apparatus based on the measuring technique developed by Ferguson and Kennedy was designed and tested. A short liquid thread was located in a horizontal capillary tube. One end of the capillary tube was connected to the pressure setup with inert gas, while the other end was left open to ambient. The open end of the capillary tube was observed with an optical setup. A pre-set overpressure of inert gas applied to the closed end of the capillary tube gradually changed the liquid meniscus at the open end from concave to planar and subsequently to convex. The surface tension at the inner liquid meniscus was determined from the overpressure of inert gas corresponding to the flattened outer meniscus. The new data measured down to -21°C from the horizontal technique agrees well with our previous measurements performed with the modified capillary rise method.
