Build, crash, and rebuild with Gears! Gears! Gears!® WreckerGears™, a hands-on 47-piece STEM building set that lets kids explore engineering and construction concepts through active play. Using sturdy, interlocking gears, kids design moving wrecker-style machines inspired by cranes, wrecking balls, and other construction equipment, discovering cause and effect as gears turn and connect. Kids can follow along with ideas in the included guide or create their own original designs, encouraging open-ended building and problem-solving. As they snap pieces together and experiment with movement, kids strengthen fine motor skills, spatial reasoning, and early engineering thinking. Designed for kids ages 4 and up, WreckerGears™ works seamlessly with all Gears! Gears! Gears!® sets, making it easy to expand builds and grow creativity over time. Ideal for home play, classrooms, or homeschool learning spaces, this colorful construction-themed set turns imaginative play into meaningful STEM learning.
