Ben Franklin Flew A Kite and Got A Charge Out of It

Ben Franklin’s Famous Experiment To Capture Electricity on 10 June 1752. Public Domain

On June 10, 1752 Benjamin Franklin conducted an experiment on electricity that has become both famous and legendary. Electricity was not well understood but many knew the effects of lightning. Franklin was fascinated by the subject and decided to conduct an experiment on a stormy day. He used a kite with a key to gather electricity the storm gave off and used string to transfer it to a Leyden jar. His son was the only witness to it. Franklin made sure he was grounded and that the string his hands were touching were not wet. Franklin’s delving into electricity would give us words we use today:battery, conductor, and electrician. He also developed the lightning rod,a very useful tool if you live in an area where you get thunderstorms. Simply put, a lightning rod on a house (or other elevated structure) acts to capture the electricity from lightning and then sends it through a wire to the ground thus avoiding it passing through the structure (which can cause damage). There are more modern variations of it but all use the same principle of grounding electricity so it does little harm to people or structures.

Attempts to replicate Franklin’s Experiment show how lucky he was and that it is difficult to do even under controlled circumstances. Some doubt it happened at all. Mythbusters found that in their recreation of the experiment he likely would have died. But they concede some parts were feasible such as collecting a charge from a damp string and accumulating it in a Leyden jar. So did it happen or not? Like all good stories, there is likely something to it. If he did do it as claimed,he was truly fortunate or blessed because it is extremely hazardous to do. Many places ban such experiments because of how dangerous it is. Whether he did as claimed or through some other means we may never know the full tale. But likely he did try something close to it and obviously he never tried it again.
