On June 15th in Science History, a significant event took place in 1752 when Benjamin Franklin conducted his famous kite experiment, which demonstrated the electrical nature of lightning.
The story goes that Franklin, who had been studying electricity and had already invented the lightning rod, wanted to prove his theory that lightning was a form of electricity. He decided to fly a kite during a thunderstorm to test his hypothesis.
Franklin constructed a kite using a large silk handkerchief stretched over a cross made of cedar. At the top of the kite, he attached a sharp wire to attract the lightning. To the end of the kite string, he tied a silk ribbon and a key.
As the storm approached, Franklin and his son William ventured outside to fly the kite. They stood under a shed to keep dry and waited for the kite to be lifted by the wind. When the kite was high enough, Franklin noticed the loose fibers on the kite string standing up, indicating that it was being charged with electricity.
Excited by this observation, Franklin moved his hand near the key and felt a spark jump from the key to his hand, confirming that lightning was indeed electrical in nature. This groundbreaking experiment paved the way for further advancements in the understanding of electricity and its practical applications.
While some historians question whether Franklin actually performed the experiment himself or if he had someone else do it for him, the kite experiment remains an iconic moment in the history of science and a testament to Franklin's ingenuity and curiosity.
Fun fact: Although the kite experiment is often depicted with Benjamin Franklin boldly flying the kite in the middle of a raging thunderstorm, it is more likely that he performed the experiment in calmer conditions to avoid the risk of being struck by lightning himself!
