How the diferential Works

[blizzard]

Here is a classic film brought to us by Chevorlet in the 1950s. It explains how the differential works and why it was created, and from this, if you can use your noodle, get a good idea of how Lockers are handy. You need to start watching the video around 1:50 in, cause before that is just a bunch of showmanship. I found this video from PopSci (Credit Where due)

Pretty much the best demonstration of how a differential works that I've ever seen.
