Ideas for A2 practical investigations to do with surface tension?

For our A2 practical investigation coursework, we have to carry out an experiment which is not a standard practical, and which has scope for development. I want to do something relating to surface tension (because I haven't about it at school but find it interesting), but am unsure about what experiment I should do in order for there to be scope to develop and explore different ideas. And I shouldn't really know the answer to whatever I'm trying to find out.

Investigating a relationship between temperature and surface tension would be too simple I think, as would a relationship between salinity and surface tension.

Does anyone have any ideas about interesting investigations I could carry out do to with surface tension?

Thanks. :smile:
