Holly,

I used to work at PSC and found the guys that set up the physics demos at
the University of Washington to be extremely helpful.  They have a Ruben's
tube and I am sure they would be happy to show you how to use it and what
all of the tricks are.  They have some other super cool sound demos that I
am sure they will be glad to show you as well.

I wish I could remember their names but I am sure a little Googling will
turn them up pronto.

This is just a tip for everybody else out there.  Get to know your local
university's physics demo coordinator.  I have found these guys to generally
be very helpful and very interesting group to work with.

Good Luck,

Mike.
