Rocket (firework)

Rocket (firework)

A rocket is a pyrotechnic firework made out of a paper tube packed with gunpowder that propels itself into the air in order to fly. Types of rockets include the skyrockets, which have a stick to provide stability during airborne flight; missiles, which instead rotate for stability or are shot out of a tube; and bottle rockets, smaller fireworks – 1½ in (3.8 cm) long, though the attached stick extends the total length to approximately 12 in (30 cm) – that usually contain whistle effects.
