To generate the sound portion of fireworks light and sound display, pyrotechnic formulas have to produce a large amount of gas in a very short amount of time. 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. - Instagram It's because of another basic law of physics called the conservation of momentum: the momentum of a firework (the amount of "stuff moving" in each direction, if you like) must be the same before and after an explosion, so explosions to the left must be exactly balanced by explosions to the right.
