A '''skyrocket''', also known as a '''rocket''', is a type of [[firework]] that uses a [[solid-fuel rocket]] to rise quickly into the sky; a '''bottle rocket''' is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects ([[pyrotechnic star|stars]], bangs, crackles, etc.) to be emitted.  Skyrockets 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.

These rockets have been made at least since the early decades of the 20th century, and in many countries, including Japan and China. The older type of bottle rocket was typically a black powder skyrocket with an engine about 2&nbsp;inches (5&nbsp;cm) long and up to 0.375-inch (9-mm) diameter, mounted on a thin bamboo splint and often having a small [[explosion|report]] charge. Modern bottle rockets are small and very cheap. They are often sold by the box (but more commonly by the pack, or by the gross, a packet of 144 rockets) for less than US$0.20 each.
