Abstract
The objective of today’s work will be to generate wrinkle patterns on very thin polymer films using the forces generated by the surface tension of a water drop. You’ll do a few sizes of water drop and we’ll give you a couple of thicknesses of film. Digital images of the pattern will allow us to make observations of the number and size of the wrinkles generated. We will try to develop an understanding of the dependence of the pattern on the materials used and the forces applied

Comments
You’ve already heard about wrinkling in various contexts. Today we’ll be looking at an exceptionally clean wrinkle pattern based on a recent research experiment conducted at UMass. This experiment is relatively simple, and can be conducted in your school, with a little practice. If you liked the pattern you created today, please contact us for materials for you to use at school.
