Why is cotton in everything? | Michael R. Stiff

Centuries ago, the Inca developed ingenuous suits of armor that could protect warriors from even the fiercest physical attacks.

Michael Stiff explores the science of what makes cotton so versatile. [Directed by WOW-HOW Studio, narrated by Addison Anderson].
