Create an exciting marble track that runs automatically! You design the course, then watch as the steel balls race freely through the tracks and tunnels. It's a fun way to study the science behind speed! Explore the link between gravity and motino by customizing your very own 51-piece track. Create exciting twists, turns, and dips - then release the marbles and see your creation come alive! Your marbles move along the track automatically, allowing you to observe the workings of speed, gravity, and motion. Build your own fast-action course with marbles that whip around corners, leap into tunnels, and rotate inside moving gears.
