{{main|Model rocket}}
A model rocket is a small rocket designed to reach low altitudes (e.g., {{convert|100|–|500|m|ft|abbr=on}} for {{convert|30|g|oz|abbr=on}} model) and [[Model rocket#Model rocket recovery methods|be recovered]] by a variety of means.

According to the United States [[National Association of Rocketry]] (nar) Safety Code,<ref name="autogenerated1">{{cite web |url=http://nar.org/NARmrsc.html |publisher=[[National Association of Rocketry]] |title=Model Rocket Safety Code |access-date=2019-10-30 |archive-url=https://web.archive.org/web/20140205202319/http://www.nar.org/NARmrsc.html |archive-date=2014-02-05 |url-status=dead }}</ref> model rockets are constructed of paper, wood, plastic and other lightweight materials. The code also provides guidelines for motor use, launch site selection, launch methods, launcher placement, recovery system design and deployment and more. Since the early 1960s, a copy of the Model Rocket Safety Code has been provided with most model rocket kits and motors. Despite its inherent association with extremely flammable substances and objects with a pointed tip traveling at high speeds, model rocketry historically has proven<ref>{{cite web |url=http://www.nar.org/safety.html |title=Safety |publisher=National Association of Rocketry |access-date=2012-07-06 |archive-url=https://web.archive.org/web/20140207062024/http://www.nar.org/safety.html |archive-date=2014-02-07 |url-status=dead }}</ref><ref>{{cite web |url=http://exploration.grc.nasa.gov/education/rocket/rktparts.html |title=Model Rockets |publisher=[[National Aeronautics and Space Administration]] |work=exploration.grc.nasa.gov |access-date=2012-07-06 |archive-url=https://web.archive.org/web/20120410054356/http://exploration.grc.nasa.gov/education/rocket/rktparts.html |archive-date=2012-04-10 |url-status=dead }}</ref> to be a very safe hobby and has been credited as a significant source of inspiration for children who eventually become [[scientist]]s and [[engineer]]s.<ref>{{cite web |url=http://www.nar.org/pdf/Organizational%20Statement%20of%20the%20NAR.pdf |title=Organizational statement of the NAR |publisher=National Association of Rocketry}}</ref>

Hobbyists build and fly a wide variety of model rockets. Many companies produce model rocket kits and parts but due to their inherent simplicity some hobbyists have been known to make rockets out of almost anything. Rockets are also used in some types of consumer and professional [[fireworks]]. A [[water rocket]] is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is usually a used plastic soft drink bottle. The water is forced out by a pressurized gas, typically compressed air. It is an example of Newton's third law of motion.

The scale of amateur rocketry can range from a small rocket launched in one's own backyard to a rocket that reached space.<ref>{{cite web |url=http://www.coloradospacenews.com/csxt-go-fast-rocket-confirms-multiple-world-records/|title=CSXT Go Fast!
