| Abstract | In this article we consider a well-known simple, very accessible demonstration of surface tension with a small boat propelled by substances that change the surface tension of water. A simple quantitative evaluation is provided that matches well with experimental data. A modification to the experiment is proposed allowing it to continue for a long time for more dramatic effect. Different molecular 'fuels' are explored with ethanol coming out as the most appropriate for educational demonstration purposes. (As Provided). |
