Honest feedback, this didn't really explain electricity for me. What is does is introduce an entirely new analogy for understanding electricity. Unfortunately, most elements of the new analogy are not relatable at all, meaning the analogy has no value. What do I care that the electrons "rotation" means charge and the speed means voltage? Why are they shaped like breathmints, how does that help if they are supposed to be gears?

At least the water and beads analogies help, because they are something I have a previous understanding of.

For what it's worth, I enjoyed the music and the typeface. Made me hang onto watching the video much longer than I would have otherwise. The VO is also good.

Yes, the main advantage over those models is that it uses atoms that are essentially shaped and moving as atoms do.

Perhaps the gearbox of your car is a relatable phenomenon for you. The breath mints are shaped like gears lol.

Perhaps a better analogy is Newton's cradle: https://en.wikipedia.org/wiki/Newton%27s_cradle

The ticking beads don't really move but transfer energy to each other. That's maybe a more useful analogy than the notion of beads or water moving through some pipe.

I'm not a physicist of course but I get that what was explained to me in high school (many decades ago) was probably a bit of an oversimplification. Ticking beads lose some energy as they smash into each other. Hence thin wires heat up and glow.

This is probably cringe-worthy enough for anyone who actually studies this for a living; so I'll stop right there ;-)

Same idea but momentum is angular in our model. Like the gearbox of a car.
