     A vuvuzela is a horn, about a meter long, usually made of a colorful cheap plastic. It is the choice of

noise-makers for South African football fans. When it's blown by thousands of supporters at the same

time, it's loud, very loud. It sounds a bit like and air horn and you can hear it a lot during the 2010 World

Cup.

     The vuvuzela was originally made from a kudu horn and was traditionally used to summon people to

gatherings. But the horn you see at soccer matches in South Africa today originated from a tin horn that

became popular with South African soccer fans around 15 years ago. A sports company began to mass-

produce a plastic version in the South Africa colors, and this is what you see (and hear) at every soccer

match. Now it's become an official symbol of the 2010 World Cup in South Africa and more popular

around the world.

     The vuvuzela will be ubiquitous during the 2010 World Cup. There was a call for FIFA to ban the

vuvuzela during the Confederations Cup that took place in South Africa in June 2009. European joumalists

got into a tizzy(紧张) about the noise. The Guardian reported:"It sounds like extremely terrible." But FIFA

stood its ground, as Mr Blatter, FIFA's president says "Vuvuzelas, drums and singing are part of African

football culture. It is part of their celebration, it is part of their culture, so let them blow the vuvuzelas."

     Adam Carnegie, a graphic artist from Cape Town, founded the Kelp Environmental Learning Project.

The project employs local men and women to collect kelp, dry it and then hand paint colorful designs on it.

The mission is simple. "We want to create jobs, make a noise, make people laugh, remind people to be in

the moment."

     Like most trumpets, getting any noise from a vuvuzela requires significant pursing of the lips and the

ability to blow with force. Your cheeks will be zinging afterward. You can personalize your vuvy blowing

techniques with a lot of practice, but generally it produces one big sound.
