Revealed: What’s In The World Cup’s Vanishing Spray!

Brazil 2014 has, so far, delivered on its promise of exciting football for its viewers all round the world, but one thing that has been of interest to plenty viewers has been the sweet blend of technology into the mix.

The much-touted goal-line technology has been introduced, mostly providing moments of comedy but nevertheless proving itself to be highly useful(France vs Honduras).

However the real star of the tournament has been the referees’ new magic spray. Used to mark out the correct distance the wall should stand from the ball at free kicks, the natty disappearing foam has taken the World Cup by storm.

Fans of South American football won’t find the foam spray new, having seen it been used in league matches on the continent for some years, but for the huge global audience, these are bold new days.

No more can the defensive wall creep forward, cramping the free kick taker’s style, when the referee’s back is turned and in theory we should now see more goals scored from free kicks.

The vanishing spray, developed Argentine journalist Pablo Silva who called it “9:15 Fairplay”, contains a mixture of butane, isobutane and propane gas; a foaming agent; water; and other chemicals. When it leaves the can, the gas depressurizes and expands, creating small, water-covered droplets on the field. The butane mixture later evaporates, leaving only water and surfactant residue behind.
