Pill box stars, also called box stars, are a unique type of star that burn very brightly for a longer duration than a comet star of the same size. They are usually metal fueled color stars, with long illuminated smoke trails behind them as they burn through the sky. Because of the extended burn time, which results from the paper sleeve around the star that prevents it from igniting on all sides, these stars will droop like parachute flares and are generally fired as single break color shells. This article explains how to make pill box stars and then produce a typical 5" color shell with them.
