Do you remember when the World Cup came around and you would watch it on your television and say, "What is wrong with the television? That noise... What is it? It won't stop." The cause for those sounds are the Vuvuzelas. They are widely used during soccer matches and was more widely recognized during the 2010 World Cup. When you blow into the instrument, a low pitched sound plays until you cannot blow into it anymore.
According to BBC News, Dr. Ruth McNerney of the London School of Hygiene and Tropical Medicine, 4 million saliva droplets per second are released when a Vuvuzela is blown compared to 7,000 per second with just shouting.
The next time you think about blowing a Vuvuzela, keep in mind the statistics. In no way, shape or form am I saying that it is not fun either. Just take precautions and be considerate of others when using a Vuvuzela.
