{"product_id":"the-runway-builders-marble-race-block-set","title":"The Runway Builders | Marble Race Building Block Set, 74 to 404 Pieces","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eGravity is the first physical law a child can test with their own hands. A marble placed at the top of a track either reaches the bottom or it does not, and no amount of argument changes the result. That is the entire premise of this set, and it is why children who lose interest in a finished model will keep rebuilding a marble run for an entire afternoon.\u003c\/p\u003e\n\u003cp\u003eThe blocks are ABS with a self-locking brick profile, which means the tower holds together while the marble is moving through it rather than collapsing the moment it takes a wrong turn. Sets run from 74 pieces for a compact starter track to 404 pieces when the goal is a structure tall enough to fill a table. Funnels, slides and track segments are included in the piece counts so the builder is never missing the one part the design needs.\u003c\/p\u003e\n\u003cp\u003eEach kit ships with a printed instruction manual and, for anyone who would rather invent than follow, the pieces are compatible with standard small building bricks already in the house. The wider run sets suit a child working alone; the larger sets are usually bought for siblings, classrooms or a birthday where two or three builders want to work on one tower from different sides.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eSome toys are finished when they are built.
