Re: [Phys-L] featured video: paper airplanes

I took Anthony's advice and ordered an X-Zylo. Meanwhile, I deprecate the dismissal  of any theory of wing lift other than flow adhesion  ~  emanating from a  physics teacher who has never, ever sampled air pressure on ports set in the first 25% of an airfoil's upper surface evidently, and who insists on visualizing "air molecules" bouncing round the wing contour.

Great video! Saw it several years ago. I send it to my students every year.
I also discuss/show other aerodynamic objects (and the world record

Toobee (86 m)
X-Zylo (200 m)
Frisbee (250 m)
Skyro (261 m)
Aerobie 13" (406 m)

I recommend getting an X-Zylo and an Aerobie. Amazingly aerodynamic! Your
students will be engaged!

p.s.  I'm too lazy to verify, as I think he was the featured speaker at a
recent NCNAAPT meeting.  We made, W/his supplied paper, planes.

He illustrated, as in the video, fluid mechanics.

Thanks BC!  That was both fun to watch and educational.
