Franklin's electricity experiments

In 1747, the fascination with electricity upon reaching the American colonies was the subject of Benjamin Franklin's first of the famous series of letters in which he described his experiments on electricity to Peter Collinson, Esq., of London. He thanked Collison for his “kind present of an electric tube with directions for using it”with which he and others did electrical experiments. “For my own part I never was before engaged in any study that so totally engrossed my attention and my time as this has lately done; for what with making experiments when I can be alone, and repeating them to my friends and acquaintances, who, from the novelty of the thing, come continually in crowds to see them, I have, during some months past, had little leisure for anything else.”«[Quoted from: "Franklin's Researches in Electricity" by Professor Edward L. Nichols in The Record of the Celebration of the Two Hundredth Anniversary of the Birth of Benjamin Franklin, published by the American Philosophical Society (1906)]
