How do fireworks scream?

The fireworks are filled with lead oxide, which turns into lead atoms as the firework explodes and heat up. These lead atoms vaporize in the huge heat and the vapours make the crackling sound as they expand.

What are fireworks made of?

Explosions: gunpowder – the explosions in most fireworks still use traditional gunpowder, composed of potassium nitrate (saltpeter), sulfur, and charcoal. Potassium is largely imported from Canada, though some is mined in New Mexico and Utah.

Why do fireworks squeal?

Fireworks generate three very noticeable forms of energy: a tremendous release of sound, bright light, and heat. The tremendous booms heard at ground level are the result of the rapid release of energy into the air, causing the air to expand faster than the speed of sound. This produces a shock wave, a sonic boom.
