Don't try this at home, folks

You know, if you do decide to film light saber battles between you and your cousin, "Darth Bob the Invincible", there's something you should know about the process. The lightsabers in the movies? They're not real. They don't actually glow like that. They use prop swords, and then the special effects guys rotoscope them in Photoshop (or whatever), making them glow after the fact.

So... with that established, no fighting with fluourescent tubes, OK, fellow Star Wars nerds?
