Powered by a built-in motor, you can recharge with a Type-C cord, and metal spheres speed through different track branches and detours.

No tools or messy glue required, just 431 laser-cut pieces that fit together snugly through a mortise and tenon joint system. Immersive, hands-on fun all the way.\u003cbr\u003eEngaging Physics Demonstration\u003cbr\u003eAdding to the educational value is the user’s clear view of concepts such as gravity, potential and kinetic energy, and momentum transfer. Friction, force, and motion interact in real time with London’s architecture as the classroom.\u003cbr\u003eQuintessential English Keepsake\u003cbr\u003eThe cleverly placed LED lighting makes this model a magnificent display of the city’s architecture and history.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"ROKR","offers":[{"title":"Default Title","offer_id":53479721009462,"sku":"EGB01","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0260\/5216\/5680\/files\/rokr-egb01-marble-travel-london-marble-run-wooden-3d-puzzle-6_1200x757_d47320b7-385d-4c60-b244-d0f8ed419b01.png?v=1765664642","url":"https:\/\/hillsborohobbyshop.com\/products\/marble-travel-london-marble-run-wooden-3d-puzzle","provider":"Hillsboro Hobby Shop","version":"1.0","type":"link"}
