Nice “short form” Instructable from user mfoster, who heats milk jug pieces to 350°F, loose, in a pot of canola oil, before pressing them into blocks using a simple scrap-wood mold and a set of manual clamps.
My German pal Aram Bartholl shows you the principles of vacuum forming with his homemade rig for churning out Guy Fawkes masks. The video takes you to 28C3 and other public venues where visitors customized their masks while learning the process.
