Orbiting Solar System

Power the planets with your finger! Build a mechanical model of the solar system that includes the sun and eight planets, wind it up and watch the planets revolve around the sun. Assemble this complex machine using squeezable plastic parts to learn how the gears and winding mechanism work to turn the model. Detail each planet with colorful, realistic planet graphics. Discover how a special type of gear called a planetary gear is used to simulate the magical motion of the solar system. Learn about the order of the planets, their relative sizes, their speeds around the sun, their appearance, and other planet facts. Bonus: There's a built-in expansion slot in case the mysterious "Planet Nine" is discovered!

• build a colorful model of the solar system.
• Winding engine makes your planets move around the sun - no batteries required
• Learn about the celestial orbits of the planets.
• Explore the mechanics of the main gears; the planets move at different speeds depending on the gear ratio.
