About this app
Firework Lab is an interactive firework design sandbox where you create your own firework! Fill the transparent shell with colored stars, try different effects, and arrange them inside the shell to shape the explosion. The colors connect to real firework chemistry: strontium, barium, copper, and sodium compounds are used to create red, green, blue, and yellow light, while magnesium burns brilliant white. Launch your shell and watch your arrangement become a colorful pattern in the sky!
