TED-Ed: From DNA to Silly Putty, the diverse world of polymers - Jan Mattingly

The video explores the concept of polymers, large molecules made of monomers, and their significance in both natural and synthetic forms. Natural polymers like cellulose, keratin, and chitin are crucial in living organisms, while synthetic polymers, derived from petroleum, have revolutionized industries. However, the environmental impact of non-biodegradable plastics poses significant challenges. The video highlights the accidental discoveries of Bakelite and Silly Putty, illustrating the diverse applications and consequences of polymer use.
