The 6-in-1 Educational Solar Robotic Kit is an excellent beginner building kit designed to teach how solar power is used to drive a small motor. Kids use the 21 snap-together parts (no tools required) to build 6 different working models including an airboat, car, windmill, puppy, and 2 different airplanes. Solar building kits teach children the benefits of solar energy, while they create a toy that’s fun to play with and requires no batteries. Educators, science museums, and hobbyists will surely appreciate the durability, educational value, and endless hours of amusement for children and adults too! Ages 10 and up.
