1. Lightning Rod

   Released in 1752 by Benjamin Franklin

   June 15, 1752, marks the legendary, albeit approximate, date of one of history's most famous scientific experiments. On this stormy day in Philadelphia, Benjamin Franklin, seeking to prove his theory that lightning was a form of electricity, flew a kite with a metal key attached to the string. As the storm intensified, he observed loose threads on the kite string standing on end, indicating the presence of an electrical charge. By touching the key with his knuckle, he drew a spark, confirming his hypothesis. This dangerous experiment was not merely an academic exercise; it was the crucial demonstration that paved the way for a practical invention to control this powerful force of nature. It established the scientific basis for the lightning rod, transforming a terrifying act of God into a predictable electrical phenomenon.
