Ping Pong, or table tennis as some people call it, has been around since the 1880s as a form of after dinner entertainment for the upper class.
It has evolved from the rounded champagne cork to the gas filled celluloid ball used today, and is considered an Olympic sport.

Ping Pong can also mean to bounce around from one thing to another, and back again, as in someone easily distracted but compulsive.
Try not to bounce around too much on this puzzle.
