Many of the products we rely on today were born from unexpected accidents rather than intentional design. Penicillin, the first antibiotic, was discovered by Alexander Fleming in 1928 when he observed that mold killed surrounding bacteria in a petri dish. Similarly, the microwave oven was invented in the 1940s by Percy Spencer, who noticed a melted chocolate bar in his pocket while working with radar equipment. The creation of Post-it notes in 1968 stemmed from Spencer Silver's failed attempt to produce a super-strong adhesive, resulting in a weak yet useful one. Other notable inventions include X-rays, discovered by Wilhelm Conrad Roentgen in 1895, and safety glass, which was created by Edouard Benedictus after a glass flask cracked without breaking. Even potato chips were an accidental creation by chef George Crum in the 1850s, born from a customer's complaint about thick fries. Lastly, Teflon was discovered in 1938 by Roy Plunkett when he found a strange white substance in a gas cylinder. These stories emphasize the significance of curiosity and the willingness to explore unexpected results.
