This is a nice little routine which gives a bit of free kino.
The first part my sister showed me: I press my fingertips on a girls back and say "how many fingers?" If i lets say put 3 fingers it will be very difficult for her to tell how many, she will probably guess wrong. I tell her if shes right or wrong. I repeat a couple of times with different sets of fingers. if I lets say put 2 fingers then 4 then 3 then 2 then 5 she will guess most of them wrong. The skin of a humans back was obviously never designed to solve tasks like this:) anyway, continue 'til its clear for her that it's impossible to count them.
This next part I just figured out: I take her hand and I do the same thing but in her palm and with her eyes closed. This time she will be able to actually feel and in her mind slowly count my fingers even if I place all five fingertips in her palm. Run the same guessing game with different numbers of fingers. She will guess right each time.
It's not amazing, but it is something to kill a couple of minuets with and a very friendly way to start kinoing. I'm going to construct an explanation of the phenomenon and maybe of evolution that is interesting and easy to follow. I've found out that some girls does not understand evolution, so if i put it right it could be quite a lesson
