According to a basic law of physics called the conservation of energy (one of the most important and fundamental scientific laws governing how the universe works), the total chemical energy packed into the firework before it ignites must be the same as the total remaining in it after it explodes, plus the energy released as light, heat, sound, and movement. So the wavelength of the perfect blue has to be very precise.

Making fireworks that produce blues has long been a challenge for fireworks chemists. Simple shells consist of a paper tube filled with stars and black powder. Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes.

This can help the fireworks move in the right direction. The materials will react with each other when enough heat is applied. The fuel is charcoal and sulfur, as in black powder. The fuel and oxidizer are proportioned, along with the other chemicals, so that the sparkler burns slowly rather than exploding like a firecracker.
