Perhaps you can search and find a really good one.
So far no luck... perhaps I should ask the question I really want
answered.
I would like to pull a small amount of air through a small tube without
obstructing the passage-way. I'm talking about a soda straw size tube and
maybe a gallon of air a minute or less.
I was wondering if maybe I could charge one end opposite the other and
get some small air flow.
