A Rocket is the generic term used for a wide variety of jet-propelled missiles, research vehicles, thrust devices and fireworks. Something can be categorized as a rocket if it has a jet propulsion device propelled by the explusion of gases in a combustion chamber.
Description
Model rockets are constructed of safe materials - such as cardboard, plastic, and balsa wood - and are fueled by single-use or re-loadable rocket motors that are commercially manufactured. These rockets may be flown over and over simply by replacing the used motor (or reload) with a fresh one. They typically contain a parachute, streamer, or other recovery device that allows them to land gently.
Today model rocket kits and motors can be purchased in almost every hobby shop and toy store. Kits are designed for all ages and all levels of challenge, from simple starter kits to complicated scale models.
