This unique plate design enables the user to fire one electric match to fire off 8 Comets in 15 seconds to a height of 140ft. The time between shots is very consistent and also holds that same consistency from plate to plate. This is very important in ensuring integral looks of your show design. To accomplish this consistency we are using a patented 'injection molded fuse material' offering a very consistent time. This fuse is then molded directly into the plastic molded plate. This slick design makes the product completely integrated which, as a result, offers a very sleek package with exceptional consistency. These plates are debris free, have no caps, no paper, no fall out……..no debris!
