DIY Lightning Experiment! Make a Shocking Capacitor

If you need a project to add a little spark to your physics class, why not build a capacitor? A video from a larger physics playlist demonstrates how a capacitor works and how to make one from easily sourced materials. As an added bonus, viewers get a behind-the-scenes look at the build as well as device testing.
