{"product_id":"9781402709005","title":"First Science Experiments: Mighty Machines","description":"How do machines work? Kids will have a blast constructing a mini-seesaw to illustrate the way a lever operates or creating their very own pulley from an empty spool, string, ribbon, pails, pennies, a broom, and two chairs. They’ll find out why they can’t put in a screw using only their fingers and examine the different parts of compound machines. In another experiment, a child’s bicycle becomes a laboratory for understanding whether wheels have to be smooth to run. A good time will be had by all.\u003cp\u003e\u003c\/p\u003e","brand":"Sterling","offers":[{"title":"Default Title","offer_id":48321559658736,"sku":"9781402709005","price":12.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781402709005_p0.jpg?v=1764100355","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781402709005","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
