Sons I knew I was right about this one the moment I kicked one of em.
Iker pointed it out absolutely perfect.
Scientists prove Jabulani ball is 'too perfect'
By Ryan Bailey
Along with vuvuzelas, controversial goals and Diego Maradona's overzealous touchline demeanor, the problematic Adidas Jabulani has become a leitmotif of South Africa 2010. The ball was designed by boffins at Loughborough University, England, and every effort was made to give it superior aerodynamics: the panels are s ched internally to create a near-perfect sphere, and Adidas' "Grip'n'Groove" technology is intended to aid consistent flight.
A set of boffins in France, however, have resisted the urge to go on strike long enough to establish that the ball has been giving inconsistent results in the tournament because it is a little too "perfect". AFP reports:
Part of the problem may be that "the s ches of the Jabulani are internal, so the ball resembles a perfect sphere," said Eric Berton, deputy director of the Ins ute of the Science of Movement in Marseille, France.I'd question whether the ball travels "a little less far", as keepers have been pinging the Jabulani from box to box with ease at this tournament, but it's unpredictability is certainly not up for debate. Iker Casillas has called it "rotten", Luis Fabiano thinks it's "supernatural", and Diego Maradona believes its uncertain flight has resulted in less long passes.
"Because of the shape, the time of contact with the foot is reduced. As a consequence, it practically doesn't spin. The ball travels a little less far, and will have a floating and unpredictable trajectory, whether for a striker or a goalkeeper."
Wind tunnel tests have been conducted by academics in Japan, Australia and California, and each suggested the ball is a bit rubbish thanks to its tendency to slow down mid-flight. The original wind tunnel tests have also been criticized as they were performed on a stationary ball, and hence they did not simulate how the ball travels during a game.
FIFA, who seem to be in an uncharacteristically apologetic mood this week, has also acknowledged the super-spherical ball has its faults. A very sensitive-sounding Secretary General Jerome Valcke said this weekend:
"We're not deaf. FIFA is not unreceptive about what has been said about the ball."While the Jabulani has been universally panned, several players have spoken positively about it: Kaka approved of the contact it offers, Petr Cech liked the way it felt, and before he used it to hit the crossbar twice with one shot, Frank Lampard said it was "true to hit". And you'll never guess which German sportswear company those players are sponsored by...
This translates to : jabulani will stop spinning in midair thus changing trajectory. The angular momentum is thus crazy and very unpredictable. Add to that wind and you get a gk nightmare. It is no wonder that never before were so many goalkeeper mistakes. I think I even posted on a different thread counting them.
If you want to take free kicks like juninho stop training and just grab a jabulani.

I think I read this exact same article in 2006 about the Teamgeist
Why do you love this ball so much?
I don't really care one way or another, but I can't blame the keepers at all. This thing does some crazy unnatural in midair, to put it mildly.
I was one of the scientists that created it and gave it to Bundesliga so Germany can have an advantage.Why do you love this ball so much?
jabulani is garbage.
Remember this gem of a ball???
now that was an instant classic. This is the one and only "Azteca" the one that Maradona used to abuse the British and other Euros.
I played hundreds of hours with that ball and it never lied!
son that's a nice pick, i remember when i was a kid i used to play with a questra ... great memories from the streets.jabulani is garbage.

lol that explains a lot... what are you? 16?son that's a nice pick, i remember when i was a kid i used to play with a questra ... great memories from the streets.
This is the one that started it all as far as that kind of design. It was expensive as too!
I had one of those, best looking ball ever. I love that it says River Plate.lol that explains a lot... what are you? 16?

son back then (1994) i was in my midlate teens .. seems like ages ago.lol that explains a lot... what are you? 16?

by the way son is that the ball with which peru let argentina score 6 times in exchange for wheat?lol that explains a lot... what are you? 16?

Or the ball which the ref claimed being the man of the match in the final against the dutch. Son we all know how rotten argentina was in 1978, no need to remember, and even with all that cheating they still needed a load of luck.
son, if you're unable to let go of your butthurtness after 32 years, i have to say i feel really sorry for you. i thought those of german descent and brazil bandwagoning were better than that. lol
son history is important and does not depend on race.
Only with history can I say how many accomplishments and what tradion brasil has etc etc .. short version: 5>>> 2
i like me some carnaval brazilian tradition very much, thank you... lol
