This rocket launcher set is designed to build children’s fine motor skills and problem-solving abilities by encouraging hands-on experiments and thoughtful exploration. Compact design: The air cannon model measures 10 cm x 6.5 cm x 11 cm (3.94 in x 2.56 in x 4.33 in), making it well suited for small hands to operate, assemble, and use. High-quality material: The pneumatic model is made of sturdy PP (polypropylene), providing a safe, robust structure that can be reused for scientific exploration. Practical learning experience: This STEM toy helps users explore the structure and operating principle of the air cannon and deepen understanding of pneumatic energy conversion. Use scenarios: - Classroom or home science activities to observe air pressure, momentum, and energy transfer. - Hands-on projects for science fairs or group demonstrations to illustrate pneumatic concepts. - Individual experiments to study assembly, function, and repeatable results.
