Today when I was coming back from a walk in my favorite park in Como, Italy, a nice group of kids approached me and started talking about our day. We talked for a while and started to say our good bye’s when a girl name Alicia Collins asked me how I came up with so many inventions with electricity. I was so happy she asked the question because I love talking about my work and how important it is to me. Everyone in her group seemed very interested so I started talking about my discoveries with animal electricity. It all started in 1791, when Luigi Galvani tried to experiment on frogs because he thought that an electronic current could be conducted through the fluid surrounding the nerves in a frog’s body. During a thunderstorm, he mounted frog's leg on a brass hook and a muscle spasm was caused when metal scalpel was used to complete an electric arc to the brass hook. The frog’s leg began to move as if it were alive. Something just didn’t seem right so I wanted to build off his experiment.
In 1800, I built a battery. It had a series of metal disks of two kinds, separated by cardboard disks soaked with acid or salt solutions. I built different piles using sixty elements. This enabled me to study the action of the pile on the electric fluid. I confirmed that the electric shock increased in intensity with the number of elements used in the pile. If more than twenty elements were used, it became painful. The first piles I constructed alternating zinc and copper discs. Each was separated by a piece of cloth dampened by an acid solution. This battery confirmed Galvani’s theory of a charge could pass through liquid.
Then I looked up to ask if anyone had any questions and no one was there, everyone just left. Even Alicia was sleeping by the tree. Another group of kids fell asleep during my speech. No surprise..no surprise. Why doesn’t anyone find this as exciting as I do?
