In 1930s Budapest, journalist László Bíró was frustrated by leaking fountain pens. He noticed newspaper ink dried fast but was too thick for pens. One day, he saw children rolling marbles through puddles — the ball left a clean trail. That moment sparked an idea 🖊. With help from his chemist brother György, he created quick-dry ink and patented the ballpoint pen in 1938. Fleeing WWII, he moved to Argentina. The British RAF needed pens that worked at altitude — Bíró’s design was perfect. In 1950, Marcel Bich bought the patent and launched the BIC Cristal. Over 100 billion sold. Bíró died in 1985. Argentina celebrates Inventors Day on his birthday 🌍. One observation changed how the world writes. #storytelling #story #history
