And perhaps we could devise some force-sensing instrumentation to determine
whether the torque exerted by the dowsing rod(s) on the hands of the user
changes when the user feels a torque tending to rotate the rod(s) into the
vertical orientation. A sleeve with force sensors at each end or the like.
I suppose if the dowsing experiment failed in that case, someone would say
there must be contact between the dowser's skin and the rod. Not sure how
to deal with that one, but I'll come up with something.
