Billions are sold every year, and they’ve become an indispensable tool for reminders, brainstorming, and even art projects. A failed glue gave rise to one of the most recognizable office supplies in the world.
Teflon: Slick Science for Everyday Life
Roy Plunkett was working with gases in search of new refrigerants in 1938 when he accidentally polymerized a sample into a waxy solid—what we now call Teflon. The substance, polytetrafluoroethylene (PTFE), didn’t react with other chemicals and had an incredibly slippery surface. Teflon soon found its way into non-stick cookware, transforming kitchens and making healthy, low-fat cooking easier. The global market for Teflon is expected to reach $3.5 billion by 2025, and its uses extend to aerospace, electronics, and even medical devices. Plunkett’s blunder is now a blessing in countless households.
Safety Glass: A Shatterproof Surprise
Édouard Bénédictus, a French chemist, dropped a glass flask coated in plastic cellulose nitrate in 1903. To his amazement, the flask cracked but did not shatter, held together by the plastic layer. This led to the invention of laminated safety glass—a key innovation for car windshields and building construction. Today, safety glass protects millions from injuries during accidents or disasters. Its widespread use in vehicles and skyscrapers has made everyday life much safer. A simple lab accident became a lifesaver for generations.
Pacemaker: A Heartbeat Away from Error
Dr. John Hopps was experimenting with radio frequencies to restore hypothermic patients’ heartbeats in the 1950s. Using the wrong resistor in a circuit, he accidentally discovered that electrical impulses could regulate heart rhythm. This error led to the first cardiac pacemaker, a device that has since saved millions of lives by helping those with irregular heartbeats. According to the American Heart Association, over 200,000 pacemakers are implanted every year in the U.S. alone. The pacemaker’s invention reminds us that mistakes can sometimes be the heartbeat of progress.
Coca-Cola: From Medicine Cabinet to Global Icon
In 1886, pharmacist John Pemberton was trying to create a medicinal tonic to help with headaches and fatigue. Mixing coca leaf extract and kola nuts, he stumbled upon a recipe that was more delicious than medicinal. Coca-Cola quickly became a popular soda fountain drink and now stands as the world’s most iconic beverage brand, with over 1.9 billion servings consumed every day. Pemberton’s accidental concoction transformed not only the beverage industry but also global pop culture.
Super Glue: Sticky Solution from a Failed Experiment
During World War II, chemist Harry Coover was attempting to design clear plastic gun sights, but instead invented a substance that stuck to everything it touched. Initially considered a failure, this super-strong adhesive was recognized for its potential years later and launched as Super Glue in 1958. Its instant bonding power has made it a staple in households and industries alike, with millions of tubes sold every year. Super Glue’s story is proof that even the stickiest situations can have a silver lining.
Silly Putty: A Toy Born from Wartime Necessity
James Wright, a chemist at General Electric in 1943, was searching for a synthetic rubber substitute to help the war effort. His creation—a bouncy, stretchy, odd-putty material—failed as rubber but fascinated everyone who touched it. Silly Putty became a beloved children’s toy, able to copy comic book images and stretch into endless shapes. The global novelty toy market, which includes Silly Putty, continues to grow, showing how a failed military material became a source of laughter and creativity for generations.
