I first found this video years ago and it completely blew me away. It is such a fantastic example of taking a subject which is completely foreign to most people (the inner workings of a differential) and making it absolutely clear and understandable to anyone. This absolutely belongs in the Explanatorium Hall of Fame.
If you don’t know how a differential works, or even what a differential is, take a look. In less than 10 minutes you will understand the basics completely.
The detailed explanation begins around the 4:00 mark, but don’t skip too quickly or you’ll miss the vintage motorcycle stunting!
