Chance Discoveries: Cellophane

This video, part of a series on "Chance Discoveries" in chemistry, traces the development of cellophane from liquid viscous cellulose, applied to fabric to protect from stains, to a thin clear film first used as a luxury gift wrap and after it was made moisture-proof, as a fundamental form of protective yet transparent food packaging.
