{"product_id":"sun-gun-telescope-kim-hegerberg-9781540444325","title":"Sun Gun Telescope","description":"Sun Gun Telescope, as featured in the August 1999 issue of Scientific American magazine, was designed so that large groups of people can view the sun safely - in particular it was created as a way to encourage children to become interested in astronomy. With this safe and portable device, both amateur science enthusiasts and professionals alike can observe sun spots. This book is a copy of Bruce Hegerberg's website www.sunguntelescope.com so that the instructions for building the Sun Gun and other astronomy related ideas he was working on will be preserved for all to enjoy for many years to come.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Kim Hegerberg, Bruce Hegerberg\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1540444325\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781540444325\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/01\/2016\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 64\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.22lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.13d","brand":"Kim Hegerberg","offers":[{"title":"Paperback","offer_id":44067337109759,"sku":"9781540444325","price":5.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_747dda00-0dee-4adc-8767-f9f34060aa2e.jpg?v=1685412625","url":"https:\/\/www.whiterainbookhouse.com\/products\/sun-gun-telescope-kim-hegerberg-9781540444325","provider":"WR Book House","version":"1.0","type":"link"}
