Sustainspark Green Firecracker is a Green Innovation replacing traditional firecrackers in cultural/religious rituals that cause severe pollution. This invention uses electronic tech (display, speaker, microcontroller) to realistically simulate lighting a firecracker string with safe, continuous visuals and sounds. It eliminates smoke, PM2.5, hazardous chemicals, and non-biodegradable waste. The system preserves faith by displaying sacred images that react to the digital lighting.
