the adidas jubilani is the official football for the world cup 2010. the balls that they use for the tournament itself are very different from the ones you buy in the shops for £20. for a start, they cost a lot more (about £150), but they are made very differently too. according to adidas:
Comprising only eight, completely new thermally bonded 3-D panels, which for the first time are spherically moulded, the ball is perfectly round and even more accurate than ever before
the video above shows how they make them. there's no commentary unfortunately, but it's still a good video. i like seeing how things are made (type 'how it's made' into the search bar for previous similar posts), and when it's to do with the world cup it's no exception!
