Corrected entry: In "DaVinci Code", Robert Langdon states that papyrus can only be dissolved by vinegar. In "Angels & Demons", he states that Galileo's text was written on papyrus so it could be easily destroyed by throwing it into a barrel of water, not vinegar.

Correction: I think he means that the ink that was written on the papyrus would dissolve/be destroyed, and that vinegar would destroy the actual papyrus sheet.
