Rocket (firework)

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.

During the tenth and thirteenth centuries the Mongols and the Arabs brought the major component of these early rockets to the West: gunpowder.

During the late eighteenth century imperialistic wars, Colonel Congreve, developed his famed rockets, which travel range distances of four miles.

The delay usually lasts just before this apex, at an optimum velocity, where a small explosion shoots the firework's stars in desired directions and thus producing a brilliant effect.

The colors, reports, flashes, and, stars are analogous to flavor one adds with spices (chemicals with special pyrotechnic properties) to a soup of otherwise bland gunpowder.
