Here’s how the experiment worked: Franklin constructed a simple kite and attached a wire to the top of it to act as a lightning rod. … Franklin moved his finger near the key, and as the negative charges in the metal piece were attracted to the positive charges in his hand, he felt a spark.
Why did Ben Franklin put a key on a kite?
In 1752, Franklin made a kite using two sticks, a silk handkerchief and string. At the end of the string, he placed a metal key in a Leiden Jar (or Leyden Jar) designed to store electrical charges [source: Code Check]. … This proved to him that lightning and electricity were the same.

What famous experiment was Benjamin Franklin known for?
Flying a kite in a storm was perhaps Benjamin Franklin’s most famous experiment that led to the invention of the lightning rod and the understanding of positive and negative charges. The connection between electricity and lightning was known but not fully understood.
Did Benjamin Franklin discover electricity with a kite and a key?
Lightning was a form of static electricity. An artistic representation of Benjamin Franklin flying a kite in a lightning storm. To further confirm his observations, Franklin devised the famed experiment using a kite and a key. Franklin described it in a letter to British inventor, Peter Collinson, who lived in London.
How did Benjamin Franklin fly a kite?
According to the 1767 Priestley account, Franklin realized the dangers of using conductive rods and instead used the conductivity of a wet hemp string attached to a kite. This allowed him to stay on the ground while his son assisted him to fly the kite from the shelter of a nearby shed.
What did Benjamin Franklin discover?
As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions.
