Surface Tension of Bubbles

Surface Tension of Bubbles A fun way to learn about surface tension and you get to play with bubbles. While having fun learns how the soap films always adopt the configuration with the least surface area. The surface tension of water can be measured with the sensitive spring scale provided. The set comprises of a trough for soap solution 6.5 inch (165mm) in dia., six metal frames of different shapes to make and manipulate bubbles, a metal ring and a sensitive spring scale. Measurements are approximate.
