Plastic tube will work and it's easy enough to drill holes in it. But can't we drill holes in glass tubes with our carbide bits?? Or would we break more of them than its worth? If a person were to try that, what size carbide would be strong enough without being excessive in size I wonder?
I have no idea, but for sure a fairly tiny hole can pass a lot of air at a fairly low pressure, so unless the holes are really really tiny the hole that's highest in the tank (least back pressure) will emit most of the air... defeating the purpose of having a number of holes.
I've arrived at the point that were I starting out I'd just use a straight piece of rigid glass or plastic tubing and be done with it. ;-)

Plastic wins. I like the "easy" part that goes with it.
Thanks
