Vanishing Spray will be great technical support for Refferie during free kicks. It is an spray by which Refferie can mark a white line for the defending wall during free kicks. This line vanishes within one minute duration making it invisible during normal course of play.
This will reduce the Refferie's tension of adjusting players and time delay for free kicks. It was invented by Brazilian Scientist Pablo Silva.
Vanishing Spray was already in use during Club WC and U-20 WC held in turkey.
