Has anyone tried using many tubes in parallel to produce a more directed air stream? This is a common practice when producing a laminar water stream (i.e. waterjet cutting and the bellagio fountain) but I can't find info on it being used for air.
I've got $40 worth of syringe tubing on my counter which I'll use to try it out. It's going to be a real pain cutting and deburring them all though.
