Magic Spray Used At World Cup
World Cup referees are carrying around a new tool this year known as vanishing spray. They use it to draw a line ten yards away from the kicker before a free kick. Rather than encroaching on the kicker, defenders must now stand behind the line until the kick is made. FIFA hopes the spray will reduce arguments and complaints related to free kicks. The water-based spray looks like shaving cream and disappears about a minute after being used. Referees carry the spray in a holster.
