THE SCIENCE OF FIREWORKS

Fireworks have captivated audiences for centuries, lighting up the night sky with dazzling displays of colour and sound. But have you ever wondered about the science behind these explosive spectacles? Behind the beauty lies a fascinating blend of chemistry and physics.

Fireworks begin with a simple ignition. A small charge sets off a chain reaction of carefully crafted chemical compounds. Different elements produce specific colours when ignited, such as strontium for red and copper for blue. These elements are combined with oxidizers to fuel the explosions and create mesmerizing patterns.

The physics of fireworks involves the principles of momentum, gravity, and aerodynamics. Shell design determines the trajectory and height of the bursts, while timing mechanisms ensure precise synchronization.

Understanding the science behind fireworks adds a new layer of appreciation for these mesmerizing displays. So, the next time you're gazing at a burst of colourful sparks, remember the artistry and scientific precision that make fireworks a true wonder of the night sky.
