Children combine tracks, curves, levels, switches, junctions, and action elements to create a path that carries a metal marble from start to finish. Different heights and track arrangements change the marble’s speed and momentum, giving children immediate visual feedback about whether their design works.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe included construction plans and challenges give new builders an approachable place to begin, while the open-ended system encourages them to move beyond the examples and invent tracks of their own.
