Currently Playing: History of the Light Bulb 1705 to 1809

The light bulb is way older than you think! Take a journey through time from Newton's assistant to glowing books to jumping dead frogs to the arc lamp all with tons of demonstrations. Links: My Patreon Page: https://www.patreon.com/user?u=15291200 The man with the glowing ball and the levitating gold flakes is from a BBC show (that is beautiful, but full of factual inaccuracies, so beware): https://youtu.be/Gtp51eZkwoI The man with the glowing barometer is from James Burke Connections 3 (which also has factual inaccuracies): https://youtu.be/eCp8h9RkaSw 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 video of the gentleman getting shocked can be seen at: http://www.ampere.cnrs.fr/parcourspedagogique/zoom/video/piledevolta/video/ Another big thank you to Tonny Cassidy for letting me use his arc lamp video: https://youtu.be/t8sUrjuyBEg Finally, as usual, a big thank you to the fabulous Kim Nalley for singing "electricity" and some background music. www.kimnalley.com
