How Stuff Works.... a lightsaber?

LOL!

Have you ever heard of the website howstuffworks.com? It is an excellent resource for learning, of course, how something works.

Well, they have outdone themselves by posting an article on how a lightsaber works. Very well done. It looks like they really researched it well and as far as I can tell it doesn't conflict with anything from fiction novels or the Illustrated guides.
