{"product_id":"electric-marble-run-3d-wooden-puzzle","title":"Electric Marble Run Wooden 3D Puzzle Model Kit","description":"\u003cp\u003eThe Lumigic Electric Marble Run 3D Wooden Puzzle turns your desk into a compact mechanical playground where motion is never-ending. This motorized marble run features a coordinated system of four-layered tracks made of spiral paths, curves, and drops in a continuous circulation system. As the motor runs, marbles speed across the structure in a looping journey, a view you can see as everything is exposed. The motor is connected to a gear-powered lift that keeps the action going by carrying marbles to the top of the structure before letting gravity take over. This miniature mechanical city in motion has 362 laser-cut wooden pieces and a 4-star difficulty rating, spanning around 12 inches wide when assembled. Turn up the excitement with this blend of fun and physics that STEAM enthusiasts, hobby builders, and collectors alike will appreciate.\u003c\/p\u003e","brand":"Lumigic","offers":[{"title":"Default Title","offer_id":45768003059873,"sku":"Electric Marble Run","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2029\/6353\/files\/WechatIMG3948.png?v=1772177236","url":"https:\/\/www.lumigic.com\/fr\/products\/electric-marble-run-3d-wooden-puzzle","provider":"Lumigic","version":"1.0","type":"link"}
