Schottenbauer "], "item_description" : "This book contains graphs designed to compare and contrast the performance of a selection of common bats and balls. These include bats made from wood, plastic, and aluminum, which are tested on an official baseball, two safety balls, plastic balls with and without holes, a wiffle ball, and a softball. Experiments show balls falling and rebounding from bats and a concrete floor, balls rebounding as they hit a piece of plywood set at various angles, and bats hitting balls from a stationary tee. These data can be used for lesson plans by teachers and parents.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/1/51/180/132/1511801328_b.jpg", "price_data" : { "retail_price" : "23.00", "online_price" : "23.00", "our_price" : "23.00", "club_price" : "23.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
