How lightsaber work!

One of my favorite movies is "STAR WARS!" Yes! why not! I always feel excited when I see a jedi uses his lightsaber to fight with hisvillains! I really love jedi, so do I really love his weapon, lightsaber.

Today, I find a topic from "howstuffwork.com" about the lightsaber. The topic is "how lightsaber works." Maybe this is just a joke, and it doesn't really happen (I think it hardly to be happen at present). The topic is about the mechanism inside the lightsaber. How the light comes out, what are the components which generates the laser, etc. These are really interesting!

I hope someday I would have a chance to try a real lightsaber. Can I use it with my professors? :D
