One of the useful methods to determine the dynamic surface tension is measuring the "maximum bubble pressure method" or, simply, bubble pressure method. Bubble pressure tensiometer produces gas bubbles (ex. air) at constant rate and blows them through a capillary which is submerged in the sample liquid and its radius is already known. The pressure (P) inside of the gas bubble continues to increase and the maximum value is obtain… http://hyperphysics.gsu.edu/hbase/surten2.html emotion recognition with facial landmark

WebMeasurement of surface tension can be performed with a force tensiometer. These instruments are based on measuring the forces exerted on a probe that is positioned at the liquid-gas or liquid-liquid interface. The probe is connected to a very sensitive balance and the liquid interface of interest is brought into contact with the probe. WebActually, the surface tension of water is too strong to make a bubble. You can try yourself to blow a bubble with plain old water, it just won't work! A good bubble solution has a detergent added to it to relax the surface tension of the water, allowing it to have more elastic, stretchy properties. Now it can act more like the skin of a balloon ...
