Carlsberg made a vuvuzela that only works if you are sober

The only thing more annoying than a vuvuzela at a sporting event is a very drunk person at said event. Carlsberg beer has come up with a way to keep those two things away from each other with its new Breathalyzela.

The only thing more annoying than a vuvuzela at a sporting event is a very drunk person at said event.  Thankfully, Carlsberg beer has come up with a way to keep those two things away from each other with its new Breathalyzela.

​

The new invention installs a Breathalyzer in the popular noisemaker so that fans who have been over-served cannot annoy their more sober neighbors.

UEFA has banned the use of the noisemaker after the complaints about the constant hum caused by the horn. That's why you haven't seen them at Euro 2016 games and elsewhere. But maybe this new technology will allow them to be reintroduced to the game in the hands of more reasonable supporters.
