Amateur rocketry involves individuals or groups designing, building, and launching their own rockets for educational, recreational, or experimental purposes. Participants often use materials like cardboard, plastic, and various propellants to create rockets that can reach significant altitudes. Safety is a key concern, and many enthusiasts follow guidelines set by organizations such as the National Association of Rocketry (NAR) or the Tripoli Rocketry Association. These hobbyists often gather at launch sites to share their projects and experiences. Competitions and events are common, allowing participants to showcase their skills and innovations. Amateur rocketry fosters a community focused on science, technology, engineering, and mathematics (STEM) education.
