A fuse comprising a fuse body having ferrules at opposing ends, a fuse state indicator located on the surface of the fuse body wherein the fuse state indicator may be temperature sensitive or voltage sensitive and a wire extending from one ferrule to the other ferrule wherein the wire is positioned along the surface of the fuse body. According to the method of the present invention, defects such as hindrance of fluorescence due to contaminant substance, low sensitivity and the like can be resolved, thereby enabling analysis on a tissue. Several different configurations of components that may be assembled as part of a finished toy are provided.
