Street Pushball (or Carboball) is game played with a three parts ball with 1.83 m in diameter that is designed as CO2 molecule.

The ball is produced at place right before the game with donated by the audience red and black clothes.

The flash mob team can number between eight and twenty players that are split on forwards, left-wings, right-wings and some reserves.

The goal is realized when the team manages to place the ball on the middle of the crossroad (opponents territory) and can be awarded with extra points if the streets are over busy. The most important safety factor requires that your ball be push and left very fast on the middle on the crossroad.

The game is designed by Petko Dourmana in 2008, as upgrade development of the traditional Pushball.

The game is planned to be taken up next year at the major European, Asian and American cites.

It was introduced for first time in Central Art Academy, Beijing, China in the frame of Summit on Arts, Culture and Climate Change organized by Asia-Europe Foundation.
