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, also just known as "rockets" have to employ some form of stabilisation technique to ensure the flight follows a predictable course. This usually takes the form of a long stick attached to the side of the motor, but can also be any other form of stabilisation, such as spin-stabilisation or fins.
In the United Kingdom firework rockets are sold by weight, e.g.: 4 oz, 8 oz, 1 lb. It is a common misconception that this weight refers to the weight of the rocket itself. In fact this is not the case, and the quoted weight is related to the bore (diameter) of the rocket motor.
The exact definition is as follows. "The weight of a lead sphere that is just supported by a tube that the rocket motor will just fit into".
