The STEM Explorers™ Marble Runners set brings hands-on engineering and problem-solving to life with an interactive marble run system. Inspired by the award-winning Tumble Trax®, this set includes 13 self-adhesive cling-back track pieces that stick to walls and windows without permanent adhesive, allowing kids to build creative runs vertically. With two balls and double-sided challenge cards, children can tackle engaging STEM challenges while developing critical thinking, spatial reasoning, and fine motor skills. Ideal for classrooms, STEM centers, or home exploration, it turns any smooth surface into a marble run playground.
