Veritasium's Big Misconception About Electricity video and the point about Poynting
We discuss Veritasium's video "The Big Misconception About Electricity". In the video Veritasium asks the question of when the light bulb in a extremely long circuit will actually light.
This point is well discussed already in several videos, see this one in particular for a good explanation of the quiz.

We focus more on the strange nature of Poynting's vector.
