Rocket (firework) century. Yet with all these drawbacks fireworks will continue to maintain their use as a traditional pastime with an ongoing history of nearly 5,000 years. Rocket (firework) 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 – 1½ in (3.8 cm) long, though the attached stick extends the total length to approximately 12 in
Antimatter rocket Antimatter rocket An antimatter rocket is a proposed class of rockets that use antimatter as their power source. There are several designs that attempt to accomplish this goal. The advantage to this class of rocket is that a large fraction of the rest mass of a matter/antimatter mixture may be converted to energy, allowing antimatter rockets to have a far higher energy density and specific impulse than any other proposed class of rocket. Antimatter rockets can be divided into three types of application: those that directly use the products of antimatter annihilation for propulsion, those that heat a working fluid
