I'm not certain that this will work since I'm so clumsy with the pooter stuff. A link to a talk that I did last year.
I'll have to try something else. Anyway, it is on youtube Bob Parks Art Talk at Schack Art Center I think that is close to it.
To any who may not know about Bob's book (I found it very enjoyable): https://www.amazon.com/Crystal-Set-High-Speed-Jets/dp/1503105679
