The Physics of the Leyden Jar in ‘MacGyver’ #MakerEducation

LeydenJarTA 85009256

Cool post from Rhett Allain up on WIRED.

IN A RECENT episode of MacGyver, Angus (that’s what his REALLY close friends call him) builds a Leyden jar with some very simple components. Of course there is some awesome physics here, so I will obviously go over this. Full disclosure—I’m currently the Technical Consult for the MacGyver show.

What is a Leyden Jar?
A long time ago, humans were just starting to figure out this whole electricity thing—in particular the study of electrostatics. The Leyden jar was originally used to store electric charge after some rubbed object is charged (like your socks in the dryer). There were two common variations of the Leyden jar, let me illustrate both.
