i had a thought for making a light saber the other day. if you took a florescent tube light and put it in a tight fiting transparent tube for stregnth and added a handle on one side with a this copper wire runing to the other end then you could make a light saber. no leds just a florecent tubelight. it would glow like a real one and could be wrapped in colored cellophane to produce different colors. it is a totally workable idea and a good one. only problem is that it won't shrink but it still would be pretty cool. the handle could house the tube driver circuit and the batters with a small switch for lighting it up.
