Benjamin Franklin Experiments with Electricity

Lightening is electricity.  It has two opposite charges (positive and negative).  Dangerous experiment with kite in storm.  Franklin’s experiments and his discoveries in his own words:

“Place an iron shot of three or four inches diameter on the mouth of a clean, dry glass bottle. By a fine silken thread from the ceiling, right over the mouth of the bottle, suspend a small cork ball about the bigness of a marble, the thread of such a length as that the cork ball may rest against the side of the shot. Electrify the shot, and the ball will be repelled to the distance of four or five inches, more or less, according to the quantity of electricity.
