If you are watching the World Cup Soccer 2010 matches being held in the South Africa, then you already know what vuvuzela is. A vuvuzela is a blow horn being played all around in the World Cup Soccer matches, and many people say it is very distracting. Now YouTube had added a feature to play the vuvuzela sound in the background of any video, just like you hear the vuvuzela being played in the World Cup Soccer matches. Here is how :
Just open any YouTube video and click on the circular soccer ball icon as indicated by an arrow in the above picture. You will immediately start hearing the World Soccer Cup vuvuzela sounds being played in the background. To stop the sounds, just click on the tiny soccer ball icon again.
