spa

so today we had a strange bio SPA practical.
the question was: which part of the skin is the most sensitive to touch?
although i am not one of the more imaginative kind, i could already see a million and one ways this experiment could go wrong.
so anyway the gist of it was, we had to poke someone at different parts of their body using 2 paper clips and determine the resolving power of their skin at that part.
naturally this experiment cant b done solo, hence...
Apparatus:
-Ruler
-Marker
-Paper clips
-Friend
friend must be included in the apparatus list.
and as for variables...
variables to be kept constant:
-Amount of pressure applied to the skin
-Honesty of owner of body
ok so no one was dumb enough to really write that for their O level spa.
but i think its a really important point.
the experiment would mean as much as dog poop if your experimentee lied, wouldnt it?
in fact that could be an experimental error.
I couldnt be sure if my friend was lying to me, hence the results may not be completely accurate.
