Octopush is underwater hockey. It was invented in the early 1950s by sub-aqua divers in South sea who got bored just swimming up and down pool lanes to get fit!
The pitch is 25m long and there are 10 people in each team, only six of these are allowed in the pool at once though. These means there are fast substitutions throughout the game and it resembles tag wrestling.
Players wear the basic equipment of a mask, snorkel, fins, and glove. They hold a small stick, about the size of a spatula, in a gloved hand. The idea of the game is to use the stick to push the puck (called a "squid") into the opposing team's goal. The goals are a 3m gully at the opposing end of the pool.
Anyone can play if they can swim and it is an easy game to pick up.
The National Governing Body for Octopush is the British Octopush Association
