This marble run set is designed for children ages 5 and up to explore engineering concepts through hands-on play. The magnetic foam track pieces allow young builders to design, test, and modify marble runs on any magnetic surface, including refrigerators, whiteboards, or oil drip pans. The set includes 14 colorful track pieces, 4 marbles, a goal basket, and 10 activity cards with pre-designed challenges to guide creative experimentation. Through play, children naturally encounter STEM principles like gravity, momentum, and cause-effect relationships. The foam pieces feature strong magnets that stay securely in place during use while remaining easy for small hands to adjust. Suitable for home, classroom, or therapeutic settings, this set offers multiple configuration options for open-ended building and problem-solving activities.
