Jedi Light Saber

My sword partner and I have given a Jedi light saber demo at science fiction conventions.  Click on the link below to go to the website where you can see it.

Scroll down to #11 on the list.  [Note: about the first 3 minutes is footage of the site where we gave the demo.] The demo starts about 3 minutes into the video.  The first part is our explanation of what we're doing, and we do the entire demo at full speed at the end.

Also NOTE:  I recently updated the link, so if you had problems finding this in the past, that problem should now be resolved.
