Mechanical DIY password box - STEM experience in mechanical engineering and inventions

Mechanical Password Box - STEM experience in mechanical engineering and security. A smart educational experience that transforms wooden pieces into a secret box that opens only with a mechanical password! The child assembles the rotating wheels and internal mechanism themselves, learns about motion transfer, gears, and mechanical coding with an understanding of safety and privacy basics in a fun and practical way. Contents of the experience: A durable wooden structure precisely designed in the shape of a secret box. 3-4 numbered rotating wheels for entering the password. A precise internal mechanical locking mechanism. Small axles and gears for motion transfer. Screws and small screwdrivers for assembly. An instruction booklet in Arabic with assembly steps and scientific principles. Features: A practical experience in gears and mechanical locking mechanisms. Learn the basics of security systems and mechanical coding in a simplified way. Develop skills in precise assembly, problem-solving, and logical thinking. Suitable for children aged 8 and above (with supervision for younger children). When assembly is complete, you can enter the mechanical password by rotating the wheels, and the box opens smoothly only with the correct password, demonstrating how mechanical locking systems work in safes and real security devices, within smart STEM activities and experiments that combine engineering and security.
