So, this DOES make for a great story, but its just a myth. There was a damn good reason we spent money on making a pen with a new style of ink that RAPIDLY absorbed and dried into paper...floating particles.

In microgravity, every pencil mark releases particles of graphite that ARENT on the paper...that eventually clog filters, get breathed in, or even worse just sit around until it gets in your eyes. However, the new pens worked better and ended up going on into the private sectors to make a lot of money. You use this invention in your day to day life...good ol American ingenuity.
