Adding different elements to a mixture can produce different colored fireworks. with very intense colors that's exactly what's happening in fireworks. 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. It turns out that if you understand these two pyrotechnic devices, then you are well on your way to understanding aerial fireworks. These are the outward-expanding bursts that we ooh and ah over.
