Expertly engineered for young creators, inventors, and future engineers, this massive 504-piece STEM construction set lets kids build a fully operational, gravity-defying marble roller coaster. Combining physical construction with real-world mechanical movement, it delivers hours of engaging, hands-on architectural play.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eThe K'NEX Marble Coaster Run transforms complex physics concepts into an interactive building adventure. Using a robust mix of classic K'NEX rods and connectors, builders assemble a complex, multi-tiered track system complete with high-speed drops, sharp hairpin turns, and looping tracks. Once fully constructed, flick the switch on the included battery-powered motor to activate the motorized chain lift. Watch in awe as the marbles are automatically hauled to the summit before plunging down the twisting tracks in a continuous, mesmerizing loop.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003eWhy Young Engineers \u0026amp; Parents Love this K'NEX STEM Set:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003e\n\u003cb data-path-to-node=\"5,0,0\" data-index-in-node=\"0\"\u003eMassive 504-Piece Building Set:\u003c\/b\u003e Packed with hundreds of vibrant, high-quality K'NEX pieces that snap together securely, offering a satisfying and durable construction experience.\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003e\n\u003cb data-path-to-node=\"5,1,0\" data-index-in-node=\"0\"\u003eReal Motorized Chain Lift:\u003c\/b\u003e Features a battery-operated mechanical motor that drives an automatic chain lift system, elevating the marbles to the top of the coaster for nonstop, infinite racing action.\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003e\n\u003cb data-path-to-node=\"5,2,0\" data-index-in-node=\"0\"\u003eAction-Packed Physics Tracks:\u003c\/b\u003e Designed with dramatic drops, tight banking turns, and kinetic stunts that teach kids firsthand about potential energy, kinetic forces, and momentum.\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003e\n\u003cb data-path-to-node=\"5,3,0\" data-index-in-node=\"0\"\u003eAuthentic STEM Learning Resource:\u003c\/b\u003e Seamlessly bridges the gap between playtime and science education by sharpening fine motor skills, spatial reasoning, three-dimensional logic, and problem-solving.\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003e\n\u003cb data-path-to-node=\"5,4,0\" data-index-in-node=\"0\"\u003eStep-by-Step Illustrated Guide:\u003c\/b\u003e Includes a detailed, color-coded instruction manual to guide builders through the structural assembly, while encouraging them to experiment and modify their tracks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"7\"\u003eSpecifications \u0026amp; Product Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"8,0,0\"\u003e\n\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eBrand:\u003c\/b\u003e K'NEX® \/ Basic Fun!®\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,1,0\"\u003e\n\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eProduct Model:\u003c\/b\u003e Motorized Marble Coaster Run Series\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,2,0\"\u003e\n\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003ePiece Count:\u003c\/b\u003e 504 durable plastic rods, connectors, track loops, and specialized accessories.\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,3,0\"\u003e\n\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003eProduct Type:\u003c\/b\u003e STEM Construction and Kinetic Building Toy\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,4,0\"\u003e\n\u003cb data-path-to-node=\"8,4,0\" data-index-in-node=\"0\"\u003eMechanical Motor:\u003c\/b\u003e Includes 1 battery-powered mini motor (Requires 2 AA alkaline batteries, not included).\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,5,0\"\u003e\n\u003cb data-path-to-node=\"8,5,0\" data-index-in-node=\"0\"\u003eIncluded Components:\u003c\/b\u003e 504 K'NEX building elements, Motorized Lift System, 3 specialized racing marbles, and a Color-Coded Instruction Booklet.\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,6,0\"\u003e\n\u003cb data-path-to-node=\"8,6,0\" data-index-in-node=\"0\"\u003eMaterial Features:\u003c\/b\u003e Made from premium-grade, highly durable, non-toxic plastic that snaps together cleanly.\u003c\/li\u003e\n\u003cli data-path-to-node=\"8,7,0\"\u003e\n\u003cb data-path-to-node=\"8,7,0\" data-index-in-node=\"0\"\u003eAge Suitability:\u003c\/b\u003e Safety-tested and engineered for young builders aged 8 years and up.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"knex","offers":[{"title":"Default Title","offer_id":42985543139390,"sku":"52012467","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/7059\/0782\/files\/81crDO2gKxL._AC_SL1500.jpg?v=1782996401","url":"https:\/\/elclebanon.com\/products\/knex-marble-coaster-run-with-motor-504-pieces","provider":"ELCLEBANON","version":"1.0","type":"link"}
