Sokolniki Park in Moscow will get a 9 metre "electric vuvuzela" for the soccer World Cup, the office of the city's mayor says.
The plastic instrument will carry the colours of the Russian flag. Through a hidden speaker it will broadcast commentary on the games played by the Russian national team. It will also "buzz in honour of winners", the city says.
An integrated microphone will make it interactive, responding to shouts and whistles with a blast of sound of the same duration – effectively allowing people to "blow the instrument".
But despite its size it is limited to output of 120 decibels, roughly as loud as a chain saw.
Russian authorities do not expect vuvuzelas to feature heavily in the streets during the tournament. They have been explicitly banned by Fifa in its "stadium code of conduct" (PDF) alongside explosives and radioactive substances.
