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.
== History ==
Developed in the second-century BCE, by the ancient Chinese, fireworks are the oldest form of rockets and the most simplistic. Originally fireworks had religious purposes but were later adapted for military purposes during the Middle Ages in the form of "flaming arrows." During the tenth and thirteenth centuries the Mongols and the Arabs brought the major component of these early rockets to the West: gunpowder. Although the cannon and gun became the major developments from the eastern introduction of gunpowder, a tickling of rockets also resulted. These rockets were essentially enlarged fireworks which propelled, further than the long bow or cannon, packages of explosive gunpowder. During the late eighteenth century imperialistic wars, Colonel Congreve, developed his famed rockets, which travel range distances of four miles. The "rockets' red glare" in the American national anthem records the usage of rocket warfare, in its early form of military strategy, during the inspirational battle of Fort McHenry, where many soldiers were killed because of the rockets.
