Underwater Hockey

Underwater hockey (also known as Octopush) is a sport in which two teams compete in a swimming pool to manoeuvre a puck sliding across the bottom of the pool into the opponent's goal with a short stick of a single material with positive buoyancy.

The sport was invented in 1954 by four divers from Southsea, England: John Ventham, Alan Blake, Jack Willis, and Frank Lilleker; however, substantial changes have occurred in equipment, team size, and other factors to make the game what it is today.
