[dook]

i must say thanks again for your help! i am on the way hopefully to building or locating a tank. however i DO have another query, which is more diver-related (i ope!) which is:

for this performance there will be vocals involved (albeit bubbly ones!)

What i am intersted in is some type of air hose that can be affixed to the nose but leaving the mouth free to make noises! Does such a device exist already? Or is there any kind of hose/mask that could be customised to do this? No air tank is required , it would act as a snorkel more than anything.

As for H&S hopefuly this wont be too risky , musicians will be supervised and the tank certainly dosnt need to be over 2 m deep! Although i know the law dosnt see it that way these days!

thanks again for your help people! When this performance comes up i will notify u all - and u are most welcome to come and watch!
