How was kevlar accidentally invented?
How do you turn a weird cloudy liquid into something stronger than steel? This week we’re telling the story of Kevlar: the chemistry breakthrough that led to bulletproof vests, firefighter gear, reinforced tires, and so much more. Along the way we talk polymers, hydrogen bonding, accidental discoveries, and the chemist who almost went to medical school instead.
