Why is the battery called a battery? Watch the whirlwind history from Ben Franklin shocking his friends to Galvani shocking dead frogs to Volta shocking himself to a Regency-era scientist loved for his big battery and good looks. My Patreon Page: https://www.patreon.com/user?u=15291200 The music is from the fabulous Kim Nalley and find her at kimnalley.com Experiments: 1. How to make a voltaic pile: Take 10 shiny pennies, 10 zinc washers (or tin foil), and cut out 10 circles in paper or cardboard. Put the paper or cardboard in a cup full of vinegar. Layer the items zinc, paper, penny, zinc, paper, penny... You got a battery! Crazy eh? 2. How to make Hydrogen and Oxygen Take a container of water and add a pinch of baking soda (you can add salt but it will make Chlorine and that is dangerous). Put leads from a 9 V battery into the water. That is it. If you put a tube with a balloon on top of the leads you can collect the gas but be careful, the gasses can be dangerous around a flame! Thanks: Big Shout out to Bertrand Wolff in France who is working with Christine Blondel on the History of Electricity. Their videos have a lot more detail on how to recreate the experiments (and how to dissect the frog). If you speak any French I recommend you check it out! The frog videos were made at their request by Dr. Francois Ferriere at the University de Rennes 1 and can be seen at: http://www.ampere.cnrs.fr/histoire/items/show/343 The videos of the voltage and maximum current from a voltaic pile as well as the gentleman getting shocked can be seen at: http://www.ampere.cnrs.fr/parcourspedagogique/zoom/video/piledevolta/video/
