What the heck is Vuvuzela?
You probably continue watching the FIFA World Cup being held in South Africa and I’m pretty sure you notice an annoying sound from an instrument commonly played in South Africa during football or soccer games. The instrument is called Vuvuzela, and it seems like you can already hear its sounds directly on YouTube.
A new button has been activated on some YouTube videos that look like a tiny soccer ball. Check out the image below.
Clicking the button will activate an endless annoying sound that sounds vaguely like a swarm of insects or like a real Vuvuzela. It doesn’t appear on all videos though; you can hear the sound by activating the button on this video.
