Kaka trying unsuccessfully to sing using a vuvuzela

Vuvuzela is known as a stadium horn which is blown by fans at football games in South Africa. The instrument made out of tin became famous in South Africa in 1990s. Vuvuzela became also controversial being sometimes banned from the stadiums because of the high noizes which distract the attention of the footballers. Being at the presentation of the official ball of the 2010 South Africa tournament, Kaka was not very happy when constrained to sing something using the vuvuzela. Besides Kaka some other of his colleagues from Real Madrid such as Xabi Alonso and Gonzalo Higuain used the blowing horn but they did not have any problems in producing some rhitmic noizes.
