SPECTACULAR SOAP FILMS - ENGLISH - Simple materials, Astounding Experiment!

Cut several plastic bottles about 10-cms from the opening. These bottles must have different slopes. Now dip a cut bottle end into soap solution. A film will be formed on the mouth and will travel towards the mouth. The speed of travel of the film depends on the slant. The more the slant of the bottle the more is the speed of travel of the soap film. This experiment is based on surface tension.
