About rocket

A rocket is a pyrotechnic firework made out of a paper tube packed with gunpowder that is propelled into the air. 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 – 4 cm long, though the attached stick extends the total length to approximately 30 cm(12 in) – that usually contain whistle effects.
