Hi pinhole,
Ok, so I'm reading the snackbook as I'm writing the fluid mechanics test,
and I find that experiment #3 "Balancing Ball" explains that the restoring
force that keeps the beach ball stabilized in the vertical airstream isn't
really due to the high speed, low pressure air in the center of the flow.
This means I've been lying again to my students -- or is it ok to attribute
this feat to Daniel Bernoulli? Any comments?
