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 KZread. 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? My Lab helper for today is named is Casey, she is 6 months old and constantly inquisitive

    I have figured out that with my grandkids, that if I simply give them a 'Toy' (one of the projects Mr. Yeany posts) they will play with it for hours. Only after they have had their fun they are more receptive to learning how it works. Hope you continue to post these for many more years. Thanks for sharing.

    These demonstrations are just wonderful. I really enjoy the simplicity of your ideas. At one moment you said that this is a demonstration of Bernoulli's principle in action. I am not sure. When the pipe gets narrower then yes, we can call Bernoulli. But the string is sucked into the pipe after the constriction, where the pipe is broad. I am not an expert in fluid dynamics but perhaps we have a low-pressure vortex after the constriction. Edit: Probably this is what happens. A fast jet of air above the constriction entrains air molecules present just after the constriction and below the jet line. It causes lower pressure. This is related to the Coanda effect.

    If you watched my original string shooter from 2014, my theory is that it was inertia carrying it forward, I was soon proven wrong, the lifting force is coming from the atmosphere's pressure being greater than the pressure of the moving air stream.

    @@YeanyScience I think your theory isnt fully correct. Of course, you are right when you write about inertia for the initial flight of the string. But what force acts on the whole loop? There are gravity which resultant is applied to the center of mass of the loop, and the aerodynamic force which acts along the string (and to what point acts the resultant of this force?). And those two forces must be equal in magnitude and must create equal torques, so they act along one vertical line. This condition defines the shape of the loop.
