Brackley business brings home the horn!
The noisy horns are the hot topic at this year's tournament: sounding like a swarm of bees on your TV and noisier in the flesh than a chainsaw.
Now they could be coming to a town, a football stadium or even a street near you too!
Businessman David Broughton's importing tens of thousands of them - hoping to use his website to capitalize on World Cup Fever sweeping the nation.
Normally his company, based near Brackley, deals with electrical goods - but he told Heart at the moment it's all about the Vuvuzelas: "During our busy times we're selling about 1 a minute. Sainsbury's called us yesterday - they're needing another 50 thousand that they asked me for. Also Clinton Cards."
There's been criticism of the noise they make - with people saying it's hard to hear the commentators in the stadium, but David thinks they can add something to a match: "Somebody said to me yesterday it's like driving a motorbike with a helmet full of wasps, which is quite intriguing. I see it slightly different to that - I think if you've got wasps buzzing around you it's ok. So if you've got three thousand fans, like some of the games we've been too, it's a really welcome addition to the game."
