Jeanne,

The link below shows a great Bernoulli-effect demonstration toy.  I'll bet Arthur could make it ... maybe even us :-)

Cheers,

Rick

Hi,
	The first web site on which I saw  a picture of this toy and two 
sentences describing it, used a flat-topped dowel, but had a link site 
in my original post.  The quick and dirty test unit which I made, also 
had a flat topped dowel.  The dowel pops out just fine.  The only thing 
that I have thought of, but have not tried is getting a tighter fit 
between the dowel and the hole.

Thanks,
  Roger
