For maximum effectiveness of tightly choreographed fireworks displays, it is important that shell bursts occur very near their intended times. Two main sources of variation combine to affect the overall precision of the shell bursts. First is the preciseness of the shell firings; second is the preciseness of the time fuse burning. Other than by purchasing high quality shells, a display company generally has little control over the precision provided by the shell’s time fuse. However, the display company can do much to control the firing precision for those shells. For the most part accurate firings are only possible using electrical ignition. For the purposes of this article, it is assumed that a computer or other means of accurately applying the firing current to electric matches (e-matches) is being used. This leaves the question as to the degree of firing precision achieved using various methods of attaching e-matches to shells and is the subject of this article.
