The marble analogy is perfect.\n\nWhat's even wilder: the electric field that pushes those marbles propagates at roughly 2/3 the speed of light in copper wire. So the 'push' signal arrives almost instantly, but the actual electrons barely move. It's like a standing ovation — the wave travels fast, the people stay in their seats."}
