Have you ever wondered why fireworks are colorful? In this article, we will discuss the science behind it.
Each firework contains a special combination of metals and salts that determine what color will appear in the sky when the firework explodes.
For example, strontium in fireworks emits a red color, barium is responsible for a bright green color, and copper produces a blue color.
Similarly, chlorine helps lighten some colors, potassium nitrate and sulfur help in the light of fireworks, and chlorine and nitrate provide oxygen for colorful explosions.
Other compounds are added to these metals and salts to help the colors explode in a wider range.
The same science applies to meteors entering Earth’s orbit. As they enter orbit, their chemical composition causes them to glow in different colors.
