Click Clack Balls: the nostalgic game of the 1970s

The bane and delight of an entire generation of children who grew up in the 1970s, the noisy and painful "click-clacks," also known as "clackers" (in their international sense), were, for a brief but intense period, a real mass phenomenon. 

Presumably inspired by boleadoras (or bolas), an ancient and curious Argentine hunting tool, they made their first appearance in the United States around 1967.
