2 sends a firework display high into the sky [syn: rocket] v : shoot up abruptly, like a rocket; "prices skyrocketed" [syn: rocket]
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. In the United Kingdom firework rockets are sold by weight, e.g.: 4 oz, 8 oz, 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."
