A skyrocket is a type of firework that uses a solid rocket motor to rise quickly into the sky. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted. Sky rockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins.
A common misconception about professional fireworks displays is that skyrockets are used to propel the pyrotechnic effects into the air. In reality, skyrockets are more widely used as a consumer item. Professional fireworks displays utilize mortars to fire aerial shells into the air, not rockets.
Sale and regulation
||The examples and perspective in this article deal primarily with the United Kingdom and do not represent a worldwide view of the subject. (December 2010)|
In the United Kingdom firework rockets are sold by weight, e.g.: 4 oz (110 g), 8 oz (230 g), 1 lb. This is not the weight of the rocket itself, but rather of a lead sphere whose diameter matches that of the rocket motor, officially defined as "The weight of a lead sphere that is just supported by a tube that the rocket motor will just fit into."
