Build this beautiful kinetic sculpture, a motorized flower model with moving petals, powered by a solar panel. Learn about mechanical systems like motors and planetary gears, and about how solar cells generate electricity to power the flower. An ingenious design allows all petals to rotate synchronously, driven by a single motor, resulting in a mesmerizing optical illusion effect. This flower will never wilt, and you will never run out of batteries; it runs whenever the sun shines on it.
