Tulemärgid

Tulemärgid, also known as fireworks, are pyrotechnic devices that produce a variety of colorful and luminous effects when ignited. They are commonly used during celebrations, festivals, and special events to create a spectacular display of light and sound. Fireworks have a rich history, with evidence of their use dating back to ancient China around the 7th century. The modern form of fireworks, as we know them today, emerged in the 13th century in China, where they were used during celebrations and ceremonies.

The basic components of a firework include a shell, a fuse, a bursting charge, and a composition. The shell is the outer casing, which can be made of paper, cardboard, or plastic. The fuse is a delay mechanism that ignites the bursting charge, which in turn sets off the composition. The composition is the mixture of chemicals that produces the light, color, and sound effects. Common chemicals used in fireworks include metal salts for color, charcoal for smoke, and gunpowder for the explosion.

Fireworks come in various shapes and sizes, ranging from small sparklers to large aerial shells. They can be categorized into several types based on their effects: sparklers, roman candles, willow fireworks, ground spinners, and aerial shells. Sparklers produce a shower of sparks, while roman candles create a fountain of sparks. Willow fireworks and ground spinners produce a variety of shapes and patterns, and aerial shells are launched into the sky to create a spectacular display.

Fireworks are not only used for entertainment but also have practical applications. They are used in military and law enforcement for signaling and illumination. In agriculture, they are used to scare birds and insects away from crops. However, the use of fireworks is regulated in many places due to safety concerns and environmental impact. It is important to follow local regulations and safety guidelines when using or enjoying fireworks.
