{"product_id":"smartivity-ultimate-marble-city","title":"Smartivity Ultimate Marble City","description":"\u003cp\u003eA big weekend build for budding engineers. Children assemble a wooden marble run full of ramps, lifts and turns, then watch their creation in action as marbles race through the city. The build teaches gravity, momentum and simple machines in a way that feels like play, not homework. It takes real focus to complete, which makes finishing it all the more rewarding. A standout birthday gift and a great project for parents and kids to build together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAge:\u003c\/strong\u003e 8-14 years\u003c\/p\u003e","brand":"Smartivity","offers":[{"title":"Default Title","offer_id":49818842464494,"sku":"TW-021","price":1499.0,"currency_code":"INR","in_stock":false}],"url":"https:\/\/www.toyswoys.com\/products\/smartivity-ultimate-marble-city","provider":"ToysWoys","version":"1.0","type":"link"}
