Skyrocket

This article is about the firework. For other uses, see Skyrocket (disambiguation).

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.

Professional displays

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

United Kingdom

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."^{[citation needed]}
