I've won a vuvuzela! During the Soccer World Cup, our local grocery chain is running a lottery where one gets scratchcards for shopping. On one of the cards, I've scratched off exactly four vuvuzela icons, meaning I now own this wonderful plastic horn, just in time for this afternoon's quarter finals of Germany vs. Argentina.
It neatly comes in the German colours, and with all necessary assembly and safety instructions (120 dB or so in front of the horn can be dangerous...)
As this is a physics blog, you may expect me to say something about the physics of the vuvuzela, but it is too hot today, and I have to prepare for the match.
Besides, there are already great blog posts on the vuvuzela, for example at
Science 2.0, where it is explained that all horns work the same way. You blow into them and that creates a vibrating column of air but the construction of the horn means certain resonant frequencies will occur, or at A quantum of knowledge. And the New Scientist has a nice interview with Trevor Cox, president of the UK Institute of Acoustics, on the sound of the vuvuzela.
And if you'd like to dig really deeply into the science of the instrument, you may try to find a copy of Fletcher and Rossing's Physics of Mucsical Instruments and have a look at the chapters on Pipes, Horns and Cavities, Sound Generation by Reed and Lip Vibrations, and Lip-Drive Brass Instruments.
Have a great weekend!
