How fireworks are made || How to make atoshbaji || কিভাবে আতশবাজি বানানো হয়।

Fireworks, known in Bengali as "আতশবাজি" (Atoshbaji), are a brilliant blend of art and science. They are crafted by carefully mixing chemicals that produce stunning colors and effects when ignited. The process begins with the creation of “stars,” small pellets made from compounds like metal salts and fuel. Each element, such as strontium, copper, or magnesium, produces different colors when burned. These stars are then packed into a shell with gunpowder, which acts as the explosive force. The fireworks shell typically has multiple chambers that house stars, burst charges, and fuses, allowing for layered effects and timed bursts. When the fuse is lit, it ignites the gunpowder, propelling the shell into the air. As it reaches its peak, the burst charge ignites, causing the stars to spread out in various colors and shapes. The size, shape, and timing of each burst can be precisely controlled to create mesmerizing displays.
