STEM stands for Science, Technology, Engineering, and Math. Our MaBoRun toys are designed to inspire your kids’ curiosity, learning, and education while delivering fun-filled, action-packed excitement! The combination of rolling steel balls, gears, levels, tracks, obstacles, and the motor provides an endlessly entertaining way for children to explore mechanics, energy, and movement. Some sets even include interchangeable parts to add building dynamics to the play! MaBoRun toys help children develop planning, observation, and problem-solving skills. As kids roll the balls through the sets, a series of cause-and-effect payoffs leads to surprise and delight, and smiles for miles!
