Instead of a bell or an airzound

do you think I could somehow mount a vuvuzela to my bike?

I once thought of mounting the ACME equivalent, with the reservoir from an Airzound to drive it, but I never got round to trying it.

Not sure.... I am usually too out of breath to be able to blow such a thing and by the time it did get winded, the object of ire would probably be miles away!

A "proper" vuvuzela is about a metre long as well - trying to figure out how it might be mounted without causing injury to the rider  

Now, on the tandem it may be a different matter!

I've often thought about carrying a hunting horn when riding the tandem.

I've got a red coat an' all.

Yes I think you should mount a vuvuzela to your bike, as long as done in a quick-release fashion.  One would be high useful for stuffing up the orrifice of an offending motorist.

As long as you're prepared to blow into it.  Adding a bulb to it would be cheating.

I don't see why not, power it with compressed air, that would wake the buggers up.
