Fuse rod

The fuse rods were objects made of Cibrianite Flux. If two fuse rods were touched at the same time without protection, they would complete an electro-neurological circuit that could render a human unconscious for at least an hour. However, if they were touched with gloves this would not happen. Sarah Jane Smith asked Maria Jackson to give them to her, but also told her to wear gloves. Then she used the fuse rods to built an energy web machine. Later Maria used the fuse rods on Mark Grantham, which knocked him out for an hour. (TV: Warriors of Kudlak)
