{ "item_title" : "The Light Bulb", "item_author" : [" Marc Tyler Nobleman "], "item_description" : "In the late 1800s, Thomas Edison created a lamp that could glow for more than 13 hours, solving a problem that had defeated many inventors in the past. But in order to invent the light bulb, Edison had to study the work of other inventors who came before him. And to this day, engineers continue to build upon this history of invention, resulting in the long-lasting light bulb technologies available today. From Sir Henry Davy's early discoveries about electricity's potential to produce light, to the LEDs of today, this book explores the invention and evolution of the light bulb.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/887/530/9798875306266_b.jpg", "price_data" : { "retail_price" : "19.99", "online_price" : "19.99", "our_price" : "19.99", "club_price" : "19.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
