Vanishing spray makes World Cup debut
The vanishing spray used by referees to mark the 10 yards distance between a free kick and the defensive wall of players made its debut at World Cup level in today's opening game between Brazil and Croatia.
The aerosol can, invented in the year 2002 by the Argentinean entrepreneur Pablo Silva, sprays a white foam-like substance that disappears from vision quickly after use.
It has previously been used in tournaments including the Argentinean Primera División, 2011 Copa America, Copa Libertadores matches and in Major League Soccer.
Use of the small can has been credited with cutting out time-consuming disputes with referees able to swiftly illustrate the place the kick should be taken from and the distance the wall needs to step back to.
