Apparently somebody thought that the vuvuzela, which provided the droning soundtrack to the 2010 World Cup in South Africa, was not an entirely bad idea. That is how the 2014 edition of the planet's greatest sporting event got the caxirola.
In September 2012, Brazilian President Dilma Roussef and musician-inventor Carlinhos Brown unveiled the official Musical Instrument of the 2014 Fifa World Cup, which UK newspaper the Guardian describes as a "plastic rattle shaped like a headless 2007-era Diego Maradona."
The maraca-like caxirola reportedly is much quieter than the vuvuzela. Experts from the Acoustic Society of America quoted by the Huffington Post said that it would take about 2000 of them to produce as much noise as one vuvuzela. But here's the rub: the caxirola is made of rigid plastic and has the potential to cause a head injury if thrown with sufficient force or lobbed from a very high seat in the bleachers.
