Initially, Franklin planned on conducting his test from Christ Church steeple, still under construction. By the spring of 1752, though, the steeple remained unfinished. Franklin grew impatient and decided to proceed without it. In June, he and his son William flew a kite with a key tied to the string in a thunderstorm.
Was there a key on Ben Franklin’s kite?
He had his materials at the ready: a simple kite made with a large silk handkerchief, a hemp string, and a silk string. He also had a house key, a Leyden jar (a device that could store an electrical charge for later use), and a sharp length of wire.
Did Franklin really fly a kite in a thunderstorm?
On June 10, 1752, Benjamin Franklin flies a kite during a thunderstorm and collects ambient electrical charge in a Leyden jar, enabling him to demonstrate the connection between lightning and electricity. … He also invented the lightning rod, used to protect buildings and ships.
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.
Who flew the kite with the key?
The story contained the familiar elements: a kite made from a large silk handkerchief, two sticks, a silk line and a key. In this account, Franklin flew the kite into a cloud, noticed unusual activity on the silk line, touched the key with his knuckle, and “perceived a very evident electric spark.”
Why did Benjamin 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 did Ben Franklin do?
One of the foremost of the Founding Fathers, Franklin helped draft the Declaration of Independence and was one of its signers, represented the United States in France during the American Revolution, and was a delegate to the Constitutional Convention.
Who really discovered electricity?
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.
