| Abstract: | A simple experimental method for measuring the surface tension coefficient of a abstersion solution is introduced. In the experiment, an abstersion solution bubble connected to a precision manometer is inflated by a syringe. By measuring the pressure change inside the bubble, the surface tension coefficient can be calculated using the Young-Laplace equation. |
