Explaining voltage on FMCG

Shared by Rob
This video should be shown in schools. It freaks me out how coolly and simply this technical concept explained.

In this clip from FMCG, Ken responds to Jeri's capacitor deconstruction with his own very visual (and very mechanical) demonstration of how voltage is generated and how you can build a simple capacitor, with aluminum foil and plastic, to generate charge mechanically and dump it into the cap (analogous to how a Wimshurst machine works).

I love how this was inspired by Jeri's demo and how the two of them are having a Net-carried, seemingly casual conversation, marveling over the miracles of science. I don't know about you, but this sort of thing makes me strangely happy.

BTW: Jeri's capacitor demo is cool too, but unfortunately, the sound craps out at the end.
