Thames & Kosmos: Marble Run

Build, experiment, and learn with this stunt-filled, action-packed marble run kit. With 60 colorful, large, durable track pieces, this kit has everything you need to design an endless variety of runs. Easily stack the securely interlocking pieces together, and then send the ten glass marbles zooming through the thrilling obstacles. Watch as they leap, flip, and spin through stunts like the air jump slide and catcher, 360-degree flip, multi-collision track, bumper steps, course-changer, and spinners.
Every stunt is more than just fun — it’s a physics lesson in action! Young builders will explore force, motion, momentum, gravity, Newton’s laws, energy transfer, friction, acceleration, deceleration, and collisions — all through hands-on trial and error. Can your marble make it through the track? If not, tweak, reengineer, and try again!
Time your marbles to compare different stunt combinations, experiment with speed, and discover what makes a faster run. When not in use, store all your marble run pieces in the included storage bag. With an eight-page illustrated manual that includes step-by-step instructions and guided experiments, this kit makes STEM learning exciting, interactive, and endlessly repeatable.
