Find contentI had been thinking along these lines.
Years back I saw a venturi insert in the barrel of an air cannon used for R&D. I forget what circumstances it was designed for, and I never used that attachment.
I figured it would be easy enough to turn a small one out of delrin and try it out. I tend to think that at this low a pressure and volume the benefits, if any, would be negligible, but I figure it's worth a quick test.
