We visit a modern sandpaper factory, where glue and gravity have been replaced by phenolic resin and electrostatic bonding.
From the ancient Egyptians, who used an abrasive paste to polish stone, to the first portable belt sander introduced in 1926, we follow the story of the ultimate smooth operator--the sander. Plus, we follow the journey of one sander that goes where no man has gone before! Find out what NASA's RAT (Rock Abrasion Tool) uncovered on Mars recently.
