by Brian Wang from NextBigFuture.com on (#6XKJ8)
This is real. Hero Tech has built a retractable light saber that is using no visual effects. You cannot fight with it but it looks like the movie light saber. The two led light strips are attached to a retractable magicians cane. The internal setup has a motor to rotate the blade and the lights.
