Create a helicopter model with a rotor that spins using a rubber band-powered motor. Assemble a spinner toy that you wind up to launch a fast-spinning top. Make a centripetal force machine that flings its arms outward at high speeds. Build a hand-mixer that demonstrates a gear train. Construct a cool aircraft launcher that flings a model vehicle across the room on a zipline. A 28-page manual guides your model building and experiments with step-by-step illustrated instructions.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Thames \u0026amp; Kosmos\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Thames \u0026amp; Kosmos\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/29\/2019\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Other\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.95lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.10h x 8.70w x 2.70d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 0814743013421\u003cp\u003e\u003ci\u003eNot available to be shipped via Media Mail\u003c\/i\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thames \u0026 Kosmos","offers":[{"title":"Default Title","offer_id":43877183520921,"sku":"0814743013421","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/3367\/0297\/files\/img_cc130dd9-1875-4175-a8d6-5fb2239341c7.jpg?v=1724789900","url":"https:\/\/bookmarksretail.store\/products\/geared-up-gadgets-0814743013421","provider":"Bookmarks Retail","version":"1.0","type":"link"}
