Spaldeen
A Spalding Hi-Bounce Ball, often called a Spaldeen or a similar ball called the Pensie Pinkie, is a rubber ball, described as a tennis ball core without the felt. These balls are commonly used in street games developed in the mid-20th century, such as Chinese handball (a variation on American handball), Australian handball, stoop ball, hit-the-penny (involving trying to make a penny flip on a sidewalk), butts up, handball, punchball, boxball, half-rubber, wireball and stickball (variations of baseball).
