There is a Bernoulli effect that suspends a disk against a surface that
has air blowing out through a large hole in the center of the surface.
This surface is facing downward. The air forced down on the disk moves
faster than the surrounding air, lowering the air pressure on top of the
disk and keeping it aloft.

We'd like to make changes to our Bernouilli exhibit, which now consists
essentially of several small blowers that can be moved around to keep
ping pong balls in the air and/or "make a basket" with them.  Does
anyone have examples of more interesting exhibits that demonstrate
Bernouilli's principle or otherwise deal with air flow and could capture
the attention of older visitors, yet be operable by younger visitors to
our children's museum?
