Baseballs are surprisingly complex. They are made of a variety of materials, including cork, yarn, rubber, and leather, providing baseballs with the aerodynamics required for America's pastime. This fun book explains how the different materials come together to give baseballs their unique characteristics, from bounce to spin. "Informative series is comprised of Books; Baseballs; Crayons; Ice Cream; Pencils; Sneakers. Although each title in this simply outstanding series is available individually, the unreserved recommendation for daycare center, preschool, elementary school, and community library collections is that the 'Making of Everyday Things' should be acquired as an intact series." -The Midwest Book Review
