Electricity doesn't work the way I thought it did

Veritasium taking on another topic after killing my brain with "Faster than the wind downwind"

I always thought of electricity as a similar case to "Newton's cradle", even though it was incorrectly taught at school to be more "river" like.
Recently saw that Veritasium video and it does puts another angle on it which is interesting.
Yeah, akin to pushing a rod. You don't have to push one end of the rod much for the end of the other end to move.Recently saw that Veritasium video and it does puts another angle on it which is interesting.
Some of the extensions and rebuttals to the video are going to be interesting to watching. It seems like Veritasium's assumptions make it far more debateable than FTTWDW.

This guy (Alphapheonix channel), does the best job so far in explaining the veritasium video.

The graphics used in the video do a good job of visualising how the electric charge from one wire passes over to the other in order to provide a short lived current through the bulb.
That's a great video thanks for the link, particularly the "cut-wire" test around 18:00. I feel slightly less confuzzled than I did before.https://www.youtube.com/watch?v=2Vrhk5OjBP8

I'm going to enjoy catching up on his other videos too, looks like another great science YT channel.

Well here's my stupid question having watched the first video:
If the power is going around the wire in the fields then why does a fuse wire blow? Surely the power is just in the field around it?
I was taught that DC and LF power went through the wire itself but as frequency increased it tended to go through the skin of the wire (skin effect) hence why some good quality high frequency wires were gold coated etc. This video suggest that even DC power goes through the fields and not the wire.
I cannot recommend enough the above linked Alphaphoenix video on the subject. Tiny amounts of power are in the omnidirectional fields. Shoving more electrons down a wire than it can handle is something else, although electrickery is still mostly a mystery to me.If the power is going around the wire in the fields then why does a fuse wire blow?
