Bring the Solar System to Life – No Batteries Needed! Build your own working model of the solar system with this hands-on STEM kit. Using snap-together parts and a wind-up gear system, you’ll create a mechanical orrery that sets all eight planets in motion around the sun.
Assemble the gear-driven system step by step and watch how planetary orbits come to life with just a flick of your wrist. Each planet features vibrant, realistic graphics, helping kids visualize the size, order, and motion of the planets in space.
This kit introduces kids to key science and engineering concepts like planetary gears, revolution speeds, and celestial mechanics—all while sparking curiosity and creativity. Plus, there’s even room to add a ninth planet if one is ever discovered!
