I thought metallic bonds created a sea of electrons on the surface of the protons
-
"the electrons can't just jump through the air from one wire to another"
Actually they can, provided you have a high enough voltage ;-)
Check my channel vid to see an example...

awesome video. You should be teaching at schools. Any news on the voltage tutorial video?
-
great video
i'm totally subscribing
-
What happened to the next video, I hope you still go through with it!

"Very handy for when you don't want to die in a terrible fire"
LOL too hard

@Ryosuke1208 i said it in my first comment but i think i didnt give much detail, i do A level biology physics and chemistry, (massive nerd) and we recently had to learn about the heart, when we got to dissect some pigs hearts most of the people where rapping the hearts round there hands cause they looked like boxing gloves, it was funny as fuck, kinda disturbed aswell

@Tarek0Kadoura You're not alone....
-
@ObservedFIREFLY What do you mean?
-
@Ryosuke1208 especially when you use the complex system of life as a boxing glove

@R4PTORZWIN I will. The next one will be on voltage, but that's going to take time to put together.

You could probably demonstrate the idea of "speed" with a line of ball-bearings (or marbles). Push a new ball onto one end and one at the other end drops off. Each ball hasn't moved far but the effect has quickly moved from one end to the other.
Great video BTW.

@Jainh872 That is an excellent analogy.

Excellent work once again, AfroTech! However, at the risk of sounding nit-picky, one minor point should be made for the sake of clarity: Only electrons from the outermost or "valence" shell of an atom are able to travel from atom to atom. Thus, only a small minority of electrons actually conduct current, while most (along with the protons and neutrons in the nucleus) remain stable, thereby preserving the physical & chemical properties of the metal. None the less, superbly done, Sir!

@flurng For anyone reading this, I deliberately simplified the hell out of the atom models. The number of electrons and the nature of the orbits is wrong, but it's good enough for explaining the nature of electric current. If you want to know more, google "modern model of the atom", "s p d orbitals" "valence band" and "conduction band". This is typically covered in upper level high school chemistry classes.
