Using snap-fit construction (no tools needed), builders ages 9 and up can put together up to 8 working models that show how cams and cranks transmit power and convert reciprocal motion into linear motion. Each build, from a fishing crane to a flying eagle, moves and functions like a small-scale machine, making the mechanics behind everyday equipment easy to see and understand.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e83 pieces build up to 8 different working models, including a fishing crane, an oil pump, a moving figure, a moving bridge, a sewing machine, and a flying eagle\u003c\/li\u003e \u003cli\u003eSnap-fit construction means no tools required\u003c\/li\u003e \u003cli\u003eDemonstrates real mechanical principles: how cams and cranks transmit power and turn reciprocal motion into linear motion\u003c\/li\u003e \u003cli\u003eEasy-to-follow building instructions guide each model\u003c\/li\u003e \u003cli\u003eBuilt for kids 9 and up who like figuring out the moving parts behind machines\u003c\/li\u003e \u003c\/ul\u003e","brand":"Flat River Group","offers":[{"title":"Default Title","offer_id":52302279377112,"sku":"G5291664004236","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/0476\/7192\/files\/tq6ojtdbjjcmm85ejqrt.jpg?v=1787674214","url":"https:\/\/www.toysrus.com\/products\/engino-discovering-stem-mechanics-cams-cranks-8-model-toy-machine-brick-building-set-snap-fit-construction-experiment-theory-kit-kids-9","provider":"Toys\"R\"Us","version":"1.0","type":"link"}
