Fireworks

Firework is a minimal explosive, pyrotechnic device that can be used for entertainment purposes.

.Fireworks are most commonly a paper or cardboard tube filled with the explosive material. A number of these tubes or cases are often combined so as to make a great variety of sparkling shapes, often variously coloured. Fireworks are generally classified as to where they perform, either as a ground or an aerial firework. Aerial fireworks may provide their own propulsion or can be shot into the air by a mortar. Ground fireworks are used to create stationary exhibitions and are commonly used on bridges and on the tops of buildings.

Fireworks can be used for aesthetic, cultural, and religious purposes. The most common use of a firework is as part of a fireworks display also called a fireworks show or pyrotechnics. Fireworks take many forms to produce the four primary effects: noise, light, smoke and floating materials such as glitter or confetti. Fireworks are popular for use at sporting events, community functions, private parties, and fundraisers. Fireworks may also be used in specialty indoor displays and at rock concerts for special effects.

In Australia, Type 1 fireworks which include sparklers, party poppers or similar are permitted to be sold to the public. For anything that has a large explosion or gets airborne, users need to register for a Type 2 Licence at the relevant WorkCover or WorkSafe authority. The Northern Territory allows fireworks to be sold to residents 18 years or older on Northern Territory Day (July 1) between the hours of 9am and 9pm for personal purposes. The types of fireworks allowed for sale is restricted to quieter fireworks, which can only be used at the address provided to the seller.
