| Abstract: | The shape of soapfilm and its characteristic and process of variation in the experiment on double funnel soapfilm are researched.An important conclusion is educed in theory and validated by experiment :the maximum distance between the two funnel is the funnel radius times 1.325.The carelessness about this problem in some textbooks is pointed out. |
