That time Benjamin Franklin tried (and failed) to electrocute a turkey
In families around the U.S. lately, persons are busily getting ready the standard turkey for his or her Thanksgiving banquet—normally in an oven, even supposing extra adventurous souls would possibly possibility private harm and go for a deep-frying approach. But when it comes to dangerous cooking strategies, Benjamin Franklin has them beat. The Founding Father as soon as infamously electrocuted himself whilst attempting to kill a turkey with electrical energy.
Franklin’s explorations into electrical energy started as he used to be drawing near 40, after he’d already had a thriving profession as an entrepreneur within the printing trade. His clinical passion used to be piqued in 1743, when he noticed a demonstration through scientist/showman Archibald Spencer, recognized for acting a number of fun parlor tips involving electrical energy. He quickly struck up a correspondence with a British botanist named Peter Collinson, and started reproducing a few of Spencer’s spectacular parlor tips in his own residence. “I was never before engaged in any study that so totally engrossed my attention and my time,” he confessed to Collinson in a single letter.
Guests at Franklin’s house have been continuously recruited for his experiments and sensible jokes. For example, he would have visitors rub a tube to create static after which had them kiss, generating an electrical surprise. He designed a pretend spider suspended through two electrified wires, in order that it appeared to swing backward and forward of its personal accord. And he devised a sport dubbed “Treason,” wherein he stressed out up a portrait of King George so that anybody who touched the monarch’s crown would obtain a surprise. (“If a ring of persons take a shock among them the experiment is called the Conspiracy,” he wrote.)
Through his experiments, Franklin used to be ready to show that electrical energy consisted of a not unusual component he referred to as “electric fire,” arguing that it flowed like a liquid, passing from one frame to every other. He studied how sparks jumped between charged items, appropriately concluding that lightning used to be simply a large electrical spark. And he coined a number of electricity-related phrases we nonetheless use lately: “charging,” “discharging,” “conductor,” and “battery,” as an example.
But Franklin had but to in finding a sensible software for this thrilling new phenomenon, which irked him very much. To that finish, he conceived of throwing an electricity-themed dinner celebration. “A turkey is to be killed for our dinner by the electric shock, and roasted by the electrical jack, before a fire kindled by the electrified bottle,” Franklin wrote to Collinson. Guests would drink their wine from electrically charged glasses so they might obtain a refined surprise with each and every sip.
It’s no longer transparent if Franklin ever hosted such an elaborate dinner celebration, however we do know that he experimented with electrocuting quite a lot of bird the use of six-gallon Leyden jars. A Leyden jar is mainly a glass jar partly stuffed with water, with a engaging in twine protruding of its cork. The jar used to be charged through exposing the tip of the twine to an electrical spark generated through friction—created through, say, rotating a glass plate in order that it rubbed in opposition to leather-based pads. There have been no usual gadgets of electrical energy again then, however fashionable estimates point out that a pint-sized Leyden jar would have had the power of about 1 joule.
The electrical surprise he first of all produced used to be enough to kill chickens, however Franklin used to be chagrined to in finding that the turkeys would recuperate from the surprise after a number of mins. Finally, he mixed a number of Leyden jars to effectively kill a ten-pound turkey, writing to Collinson that “the birds killed in this matter eat uncommonly tender.”
But in December 1750, Franklin realized a exhausting lesson at the significance of grounding in his electric experiments. In a letter dated December 25, possibly to his brother, he described but every other strive to electrocute a turkey to entertain his visitors. “I inadvertently took the whole through my own arms and body, by receiving the fire from the united top wires with one hand, while the other held a chain connected with the outsides of both jars,” he wrote.
Guests reported seeing a flash and listening to a loud crack like a pistol firing, and Franklin used to be momentarily knocked mindless, even supposing it seems that he remained on his toes. (“I did not fall, but suppose I should have been knocked down if I had received the stroke in my head,” he wrote.) He discovered his frame shook for a number of mins, and described a numbness in his hands and the again of his neck, which wore off through the following morning. There used to be a telltale swelling on one hand from the surprise, and he used to be sore for a number of days after. While he gave his brother permission to percentage his revel in with a colleague, James Bowdoin, who additionally experimented with electrical energy—essentially as a cautionary story—Franklin admitted to being ashamed “to have been guilty of so notorious a blunder.”
That did not stay Franklin from proceeding his electric investigations. He carried out his well-known kite-and-key experiment in June 1752, at the outskirts of Philadelphia. He built his kite body out of 2 strips of cedar nailed in combination within the form of an “X,” and stretched a huge silk handkerchief around the body. He hooked up the important thing to a lengthy silk string dangling from the kite, attaching the opposite finish to a Leyden jar with a skinny steel twine. Then he took the kite into a box all the way through a thunderstorm, status beneath a small shed to stay dry. When he noticed free filaments of wire “stand erect,” indicating electrification, he pressed his knuckle to the important thing and gained a small surprise, thereby proving that lightning used to be certainly static electrical energy. He went on to invent the lightning rod, amongst different inventive units.
As for the use of electrical energy to kill and tenderize a turkey, sooner or later Franklin had completed enough experiments to supply very particular directions to two French colleagues, Jacques Barbeu-Dubourg and Thomas-Francois Dalibard, who have been reasonably willing to take a look at his approach. His directions referred to as for 6 huge Leyden jars to kill a ten-pound turkey. He ended his letter along with his hard earned knowledge concerning the risks concerned: “The one who does the operation must be very aware lest it happen to him, accidentally or inadvertently, to mortify his own flesh instead of that of his hen.”
