How Everyday Things Are Made

A nice online course that goes over many aspects of manufacturing. It was posted on slashdot a couple of days back.
How are M&Ms coated? How are glass bottles molded? How do you put stuffing in chocolates?

I was surprised by the lack of reaction by slashdot readers (few comments). Although I've had some experience in manufacturing, what striked me in the course was how different software is.

I also recommend the excellent HowStuffWorks site.
