String Shooter Pipes....air driven

String shooters have become a popular toy over the past few years. Since posting a video showing two spinning wheels spitting out a 16 foot loop of string, quite a bit of insights into the science behind it's behavior has been posted through a number of sources including published papers and a number of videos posted on YouTube. In this video, I'm demonstrating a far simpler method of launching a loop of string using a high speed air stream. Drinking straws launch strings using lung power for small versions while vacuum exhaust launches larger versions. While it's path may match that of the wheel propelled shooter, I think the explanation of it's launch may have additional complexity, or at least I don't have an understanding of them as yet. Questions such as what would be the best ratio of air speed to string speed? what happens to the string as the two speeds become closer? At what point does the loop break down into a chaos on the outgoing pathway?
