I was reading an article on why fingers wrinkle in water (Link below) that said that recent studies have shown that wrinkling of finger tips is a neurological response and has evolved over time. Can you propose any further experiments to do with wrinkling of fingers?
Thanks, I find this topic really interesting and would like to do some experiments on it myself. Please suggest any other ideas and possible hypothesis' you have.

I recently read an article in the NY Times, science section on the adaptation of wrinkling of fingers. Apparently, it allows for a much better grip on wet objects, when the hands are wet. This is an interesting adaptation. Apparently, it gave an evolutionary advantage to humans handling wet objects. People are approximately 12 percent quicker at moving wet objects with wrinkled fingers. Why not design an experiment investigating reaction time and doing a certain task in two groups--a group with hands that were submerged in water for 15 minutes versus a group with dry hands. Their task may be to grasp wet objects and transfer them to a bin, in a given time period. You can make your experimental group the group with wet, wrinkled fingers, the control group is the group with dry fingers. The independent variable is wet, wrinkled hands and the dependent variable is the reaction time for moving the wet objects. It would be interesting to see if the article is correct about the wrinkled adaptation.
