6. Tissues, Travel Trailers, Slippers, Motorcycle Helmets

Wood pulp is transformed into thin sheets of soft paper before being cut, folded and boxed as facial tissues. Insulated walls, plumbing, electrical systems and furnishings are installed on wheeled chassis to build travel trailers; fabric, padding and soles are joined into slippers; and protective shells, impact-absorbing liners and retention straps are assembled into motorcycle helmets.
