The Leyden jar was used to conduct many experiments on electricity as early as the 18th century, it was the first instrument used to accumulate electrical charges, which could be discharged at will by the experimenter. They are still used today for educational purposes to demonstrate the principles of electrostatics and in the past they were used to charge conductors. The invention is attributed to the Dutch physicist Pieter van Musschembroek who presented it to the scientific community in 1746, baptizing the instrument with the name of his city, Leiden, which was also the seat of the university where he held the professor's chair. Leyden jars were often used in board games, to make a chain of people holding hands feel the shock. The person at the beginning of the line touched the outer metal plate of the bottle and the last person touched the ball inside the bottle. All the people who made up the chain felt the shock. Good condition.
