Surface tension in soap films: Revisiting a classic demonstration
European Journal of Physics
We revisit a classic demonstration for surface tension in soap films and introduce a more striking variation of it. The demonstration shows how the film, pulling uniformly and normally on a loose string, transforms it into a circular arc under tension. The relationship between the surface tension and the string tension is analysed and presented in a useful graphical form. © 2010 IOP Publishing Ltd.
