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 does a kite and a key have to do with Benjamin Franklin?
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 tie a metal rod to a kite?
Franklin hypothesized that lightning was an electrical discharge. Before he thought of conducting his experiment by flying a kite, he proposed erecting iron rods into storm clouds to attract electricity from them.
Did Ben Franklin really tie a key to a kite?
Instead, in 1752, he devised a new plan: sending a kite into the air. … Franklin stood outside under a shelter during a thunderstorm and held on to a silk kite with a key tied to it. When lightning struck, electricity traveled to the key and the charge was collected in a Leyden jar.
What did Benjamin Franklin do with a key?
On a dark, stormy summer night in 1752, Benjamin Franklin flew a kite with a key attached to the string waiting in anticipation for lightning to strike. The dramatic bolt would harken the discovery of electricity (or as Franklin called it “electrical fire”) … or so the story goes.
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.
What was the purpose of the kite experiment?
The experiment’s purpose was to uncover the unknown facts about the nature of lightning and electricity, and with further experiments on the ground, to demonstrate that lightning and electricity were the result of the same phenomenon.
Did Ben Franklin invent the lightning rod?
“The lightning rod was invented by Benjamin Franklin, but perfected decisively by Nikola Tesla.”
Did Ben Franklin invent the stove?
In 1742, Franklin—perhaps fed up with the cold Pennsylvania winters—invented a better way to heat rooms. The Franklin stove, as it came to be called, was a metal-lined fireplace designed to stand a few inches away from the chimney.
