The vanishing spray is to be utilised at a FIFA competition for the first time, with referees set to test it during the FIFA U-20 World Cup Turkey 2013 between 21 June and 13 July.

The spray is aimed at giving match officials the opportunity to mark a line on which the defending team must line up its defensive wall before a free kick is taken. Produced by the Argentinian company Fair Play 9.15 Limit, the spray marks a white line on the grass, which indicates clearly any attempted encroachment by players aimed at narrowing the angle or affecting the taking of the free-kick.

The spray is a non-contaminating foam that can be used on grass, synthetic and dirt pitches, and disappears between 45 seconds and two minutes of being applied. It will be used on a trial basis in all 52 matches of the FIFA U-20 World Cup in Turkey.

All referees deployed in Turkey are on the list of candidates for 2014 FIFA World Cup Brazil™, and each received a technical and practical instruction during the a preparation seminar last month in Rio de Janeiro. 

The International Football Association Board (IFAB) approved the spray's use during the board’s 126th Meeting, in Surrey, Great Britain, on 5 March 2012, and determined that any confederation, member association or league could use it in future if they wished.
