I *know* it's far more conductive than plastic in humid Boston weather,
since I was using paper strips as conductors when driving the pop-bottle
electrostatic motor with a VandeGraaff machine.  Brown paper from paper
bags worked better than bond.

Speaking of pencils, I found that india ink has enough carbon that it
behaves as Aquadag.  For home-made VandeGraaff machines, one can make the
conductive sphere electrode out of papier mache, then paint it with a
couple of coats of india ink.
