The Addidas company created a soccer ball designed to take out any questions, and maybe a bit of fun, out of calls made by football referees.These hi tech, chip-embedded soccer balls are supposed to alert referees by way of radio signals when soccer balls go over the goal line. The sensors on the soccer ball send the signal to special watches that are worn by referees telling them that the ball did in fact cross the goal line. Future drunken arguments in European bars may be over faulty sensors and not faulty vision.
