Fireworks are low-explosive pyrotechnic devices used mainly for aesthetic and entertainment purposes in a fireworks display. Fireworks produce noise, light and smoke, and disperse floating materials. They are generally burnt at nighttime to give out colored flames and sparks. The display of fireworks is a common sight on New Years Eve, Independence Day, Christmas, and at weddings, birthdays and parties. For any grand occasion, one loves to celebrate with fireworks.

Fireworks are categorized primarily into two types: the ""large"" fireworks that are used in shows and the ""small"" fireworks that are bought by general public. Nowadays there are organizers who specialize in making and displaying fireworks in large public gatherings. And when there is a theme and some music associated with the fireworks display, it leaves a stupendous impression on the people who are watching it.

Fireworks are made of two major components, called gunpowder and sparkles. Gunpowder is made from charcoal, sulfur and potassium nitrate, while a sparkler is a combination of fuel, oxidizer, iron or steel powder and binder. Putting them together in a professional and safe manner generates a variety of sparkling, colorful effects that can fill the night sky with brilliance. Effects have names like peony, chrysanthemum, dahlia, willow, palm, Roman candle, rockets, spinners and fountains, based on how the fireworks look once they are lit. Many popular brands like Satellite, Brothers, Black Cat, Phantom and Zambelli produce a wide range of fireworks. There are special dealers that sell fireworks, or you could order them on the Internet.

But there are a few safety considerations to be kept in mind before you start lighting these fireworks. Select the site and your clothing carefully. Keep some water handy in case of fire. Read all the instructions carefully before lighting them. Pets and children need to be taken care of properly if fireworks are being displayed. And after the show is over, be prepared for the pollution it leaves behind!
