Abstract: Polysulfide sparklers are renowned for their delicate spark display and complex reaction dynamics, rooted in the centuries-old Japanese tradition of Senko Hanabi. However, modern challenges such as regulatory restrictions and manual production costs threaten their survival. Recent innovations—including the use of (bi)carbonate-based compositions and the integration of metal powders—have significantly improved safety and visual performance. This study introduces a pellet-based design called the Dragon Tear, which standardizes the sparkler’s core composition for better reproducibility and ease of handling. These pellets can be safely stored, transported, and later wrapped in paper by the end user to create a functional sparkler. With added magnesium or magnalium, the design produces a striking glitter effect in the final phase of combustion. The Dragon Tear bridges traditional beauty with modern practicality, offering a scalable, low-risk alternative that preserves the art of polysulfide sparklers for future generations.
