Video Swap (Patreon)

Just a quick note: I'm having to re-upload the new video because a sharp-eyed patron spotted an significant error in one of the animations (the magnetic polarities in Ellie's explanation of electric motors were backwards).

I had to delete the original video first in order to upload the new one, so if you're trying to watch the early access link at this time, it won't play. With it went all your lovely early YouTube comments, but I still have them as email notifications.

Sorry for the inconvenience, but this really makes me glad I do this advance screening. It gives us a chance to spot gaffs like this :)

I'll update the link as soon as the new video becomes available!
