0:00 In 1851, Elias Howe—the inventor of the sewing machine—patented something he called an "Automatic, Continuous Clothing Closure," and then did absolutely nothing with it.0:11 This feels a lot like our deep dive on the ballpoint pen, where the perfect solution was just sitting there, ignored.0:19 Ignored because he was busy with the sewing machine!0:23 He couldn't see the second forest for the first tree.0:27 But the real failure came forty-two years later with a man named Whitcomb Judson.0:32 He marketed a "Clasp Locker" for boots.0:35 It was a disaster.0:36 It used a clumsy hook-and-eye system that would randomly pop open.0:41 So the first zipper didn't...0:43 zip.0:43 Not at all.0:44 It was a party trick that embarrassed you at the party.0:48 The company was bleeding money until they hired a Swedish-American electrical engineer named Gideon Sundback.0:55 And this is where the obsession pays off.0:58 Sundback looked at Judson's mess and rebuilt it from first principles.1:03 What was the core problem he had to solve?1:06 The teeth.1:07 Judson’s hooks were unreliable.1:09 Sundback’s breakthrough, his "Hookless No.1:12 2" from 1913, was to change the shape of the teeth themselves.1:16 Instead of a hook and an eye, he designed each tooth with a tiny scoop on its head and a little dimple on its bottom.1:24 Wait, a scoop and a dimple?1:26 Exactly.1:27 The Y-shaped slider forces the scoop of one tooth to clamp perfectly onto the dimple of the tooth on the opposite side.1:35 It's a beautiful, self-correcting geometry.1:38 That simple change is everything.1:40 This feels like the adoption of the automobile.1:43 You have these early, terrible, unreliable versions that barely work, and then suddenly Henry Ford creates the Model T and it just...1:53 goes.1:53 Sundback is the Henry Ford of fasteners.1:56 That's the perfect analogy.1:58 And it holds!1:59 Because just like the car, nobody wanted it at first.2:02 For twenty years, it was seen as a novelty.2:05 It took B.F.2:06 Goodrich putting them on rubber boots in the 1920s—and coining the onomatopoeia "zipper"—for it to catch on.2:14 Then Esquire magazine runs a "Battle of the Fly" campaign in 1937, pushing zippers over buttons for men's trousers.2:22 The "Battle of the Fly." I can't believe that was real.2:25 But here’s where the analogy breaks.2:28 The car changed public space—how we move between cities.2:32 The zipper changed private space.2:34 It introduced speed and ease to the act of dressing and undressing.2:39 It changed our relationship with our own bodies.2:42 It’s a mechanism for privacy, but also for access.2:45 Yes!2:46 From military flight suits in World War Two to a child learning to put on their own coat.2:52 The sound of a zipper is now a universal signal.2:55 It's the sound of something either being revealed or secured.
