New at the Prop Store of London: an Alliance shock rod! Lights up and everything. From the description:
A fantastic light up hero shock rod used in the Maidenhead Bar in the sci-fi adventure Serenity. These can be seen in the scenes at the Maidenhead Bar held by one of the guards. Made from machined aluminium with the handle and stripes on the other end anodised black. The tip of the prop has a white ascending light inside which is activated when a tiny button on the side of the handle is depressed. It measures 43cm (17″) in length. The prop was not used in the final cut of the film.
