When the 2014 FIFA World Cup gets started on June 12 in Brazil , the world ’s greatest soccer role player will be booting around one of the most advanced ball ever created for the sport — and the science proves it .
call in Brazuca , it was developed by Adidas . Here ’s what make it unique :
It has six polyurethane panel that are bonded to keep the ball the same weight and plumpness in even the thickest of rain ( it ’s the first time a clump has had so few panels )
The never - before - look panel shape revolutionize the game by get faster flight speed and maintaining reliable roundness
The bladder of the Brazuca clump is made of latex and provides the trust recoil
The glob is textured and feels more like the Adidas ’ Finale 13 , the prescribed UEFA Champions League lump , than the Adidas Jabulani used in South Africa four long time ago
The adidas Brazuca ball , in a sheer lily-white / nighttime blue / multicolor colorway befit Brazil , is the most colorful ever for a FIFA World Cup

Typically , association football ball are made from 32 pentangular and hexangular panels . Recently , however , newer balls have featured 14 and 8 dialog box excogitation . But with this six - panel design , the testis is expected to demonstrate optimal aerodynamic persistence and escape speeding .
To prove it , Nipponese researcher Sungchan Hong used wind tunnel test and a gripe - robot to try out the relationship between the panel shape and orientation of modernistic footballs and their aerodynamic and flying characteristics . The outcome now appear in Nature : Scientific Reports . Tim Newcomb from Popular Mechanicssummarizes it nicely :
Hong says the new globe has a “ stable flight trajectory thanks to the pattern and number of panel that it is constructed from . ” The characteristic of the panels on a association football ball have a “ substantial impingement on how the ballock travels through the air , ” Hong says .
Hong and Takeshi Asai tested the ball by mount them in a wind burrow to test aerodynamic properties . They also used robots to kick the ball toward a destination 25 meters away and evaluate ball rotation , net encroachment degree , and trajectories . Curiously , while Adidas has been steadily quash the figure of dialog box over the geezerhood , the scientists find that less is n’t always more . While the six - panel Brazuca was the best performer , a conventional 32 - panel musket ball follow it closely , the study say . Adidas is well-chosen to forget the eight - panel knuckling Jabulani from the 2010 World Cup in South Africa — goalkeepers decried its fluttering and striker lamented its inconsistency .
The Brazuca and the 32 - panel clump had “ relatively static ” data point , whereas other balls in the study differ greatly base on how the globe ’s panels were face prior to the robot ’s impact . “ The changes in the flight characteristics ( points of impact ) of Cafus and Teamgeist 2 with the board orientation were particularly drastic , which indicated that their panel orientation significantly affected their flight characteristics , ” the research worker say .
This all sounds large — but wind tunnel and kick - robots are one thing , actual game - dramatic play is another . I ’m amply expecting the players to quetch about it like they usually do .
