ORBITING SOLAR SYSTEM
Kids can set the planets in motion with a flick of their wrists! Build a mechanical model of the solar system, including the sun and eight planets, wind it up, and watch the planets revolve around the sun. Assemble this complex machine — also known as an orrery — using snap-together plastic parts to learn how gears and wind-up mechanisms work to spin the model. Planets feature realistic-looking graphics and travel at different speeds. Kids can set the planets in motion with a flick of their wrists!
