This is so cool. You can now make a very realistic looking lightsaber by using a couple of basic plumbing equipment. I am gonna try it out really soon, if I can get the parts.
I still remember that one time when I was out with a girl friend, and being the gentleman that I am, I offered to carry this tube she had, it contained a movie poster. We were waiting for the train to arrive, so just for fun I started swinging the tube like a lightsaber and making that whirling lightsaber sound.
Her reaction was not what I hoped for. She stared at me incredulously, like I was crazy or something, and then quickly snatched the tube back from me. And then she called me a dork, among many other things. Sigh. Women.
