Surface Tension Experiment.

By Roberto Eduardo López.

We want to be able to measure the surface tension on soap films. We used two techniques, the first one called Bergmann's deflating bubble and Potential. For both experiments we made 3 differents soap solutions from scratch with same ingredients but different concrentations. We called the solutions Soap Solution I, Soap Solution II and Boy's Book  Soap Solution.

For Bergmann's experiment we used two methods:

            Excel Curve Fitting for        

            Least Squares Method
