Rocket fireworks are a type of firework that is launched into the air by a rocket propulsion system. They typically consist of a small cylindrical tube containing explosive materials that are ignited to create a powerful upward thrust. Once launched, the rocket travels through the air before reaching its peak, where it explodes to create a bright, colorful display of light and sound.

Here are some key features of rocket fireworks:

1. Launch Mechanism: Rocket fireworks are attached to a stick or rod that helps stabilize the flight. This stick is used to guide the rocket in a straight line as it ascends.

2. Flight: The rocket is propelled into the air by the force created when the explosive charge is ignited. The propulsion burns until the rocket reaches a certain height.

3. Bursting Effect: After the rocket reaches its peak height, it explodes in various shapes and colors, often with multiple effects such as crackling, flashing lights, or bursts of different hues.

4. Variety of Effects: Some rocket fireworks may also have additional effects, such as trailing stars or smaller bursts during the ascent before the main explosion.

Rocket fireworks are popular during celebratory events like New Year's Eve, Fourth of July (in the U.S.), and other festive occasions. However, due to their potential for mishandling, they are subject to safety regulations and restrictions in many areas.
