Mechanical toys are playthings that operate using simple machines and mechanisms, often powered by wind-up springs, gears, or levers. These toys can move, make sounds, or perform actions without the need for batteries or electricity. Common examples include wind-up cars, toy robots, and music boxes. These toys have been popular for centuries, captivating children and collectors alike. They encourage imaginative play and help develop fine motor skills as children learn to operate the mechanisms. Mechanical toys can also serve as educational tools, introducing concepts of physics and engineering in a fun and engaging way.
