Trivia: What was tied to the end of Benjamin Franklin’s kite?
A copper coin
The correct answer is A key
So why is this answer correct? : In Ben Franklin’s famous electricity experiment in 1752, he tied a key to the end of a kite, which he flew into electrically charged clouds. Electricity came down the kite and traveled through the string into a key, which charged a Leyden jar — a jar that stores a high-voltage electric charge.
