Πειραματισμός βασανιστηρίων με γαργαλητό

I'm running this experiment with lots of girls, lots of students, and volunteers.

We're also recording this so that we can use these films to study the differences in the different tickle responses with my series of subjects.

This should be *******.

This is good. I think so far that's my favorite area of the tickle.

Let's try the backs of the legs. Knee pitch.
