Abstract
A simple experiment for measuring the surface tension coefficient is proposed, which is well suited for teaching and learning the behavior of liquids in typical student laboratories. It is based on the pull-off method and the dynamometer used is the Jolly balance. The experiment requires inexpensive equipment but the methods allow for serious analysis of possible systematic errors, such as the impact of the state of the spring and wire on the experimental results, and the unusual movement of the engraved line on the mirror when pulling up the water film.
