WHAT’S INSIDE A FIREWORK? The source of most fireworks is a small tube called an aerial shell that contains explosive chemicals. An aerial shell is made of gunpowder, which is a well-known explosive, and small globs of explosive materials called stars.
The stars give fireworks their color when they explode. The beautiful colors come from the explosion of stars, which form spheres, cubes or cylinders that are usually 3-4 centimeters (1-1.5 inch) in diameter.
