Elastic Band Flying Bird Key benefits Handson science and engineering: children explore basic physics and aerodynamics through building and flying the model. Safe, collaborative activity: lightweight frame supports a parentchild, handson learning experience. Adjustable flight performance: tune wing span, chord length, center of gravity, and elastic band tension to explore lift, stability, and distance. Educational and creative: promotes environmental awareness and sparks curiosity about flight design. Standout design and features Filmlike covering on wings and fuselage demonstrates real aircraft aesthetics and design concepts. Lightweight, easytobuild frame makes the project approachable for beginners. Birdinspired wing shape improves airflow on the upper surface to support lift. Elastic band power provides a quiet, simple propulsion method with controlled releases. Dynamic control system enhances distance, altitude, and stability during launches. Product attributes Function: elasticband powered flying model for indoor/outdoor STEM play and exploration. Material: filmlike covering for wings and fuselage; lightweight frame. Size: compact and lightweight design (explicit dimensions not stated). Performance: adjustable parameters to achieve stable, upwardflight lift. How it works Assemble the lightweight frame and attach the filmlike wings and fuselage. Load and secure the elastic band; adjust wing span, chord length, center of gravity, and band tension. Release to launch; observe how wing design and tuning affect lift, stability, and range. Use scenarios Family STEM time: build, tune, and fly together in the backyard or a safe open space, integrating learning with play. Classroom or science club: use as a demonstration of lift, stability, and the impact of geometry and center of gravity on flight. Outdoor park activity: experiment with band tension and wing parameters to maximize distance and altitude in calm to mild wind conditions.
