Derek,
In hopes you didn't give up on this list altogether, here's a little
puzzle you might enjoy. There is a demonstration of the Feynman
sprinkler puzzle somewhere at MIT.

What simple modification could you easily introduce to the nozzle in
order to demonstrate a force due to suction as well as that due to
pressure? Perhaps I could hint that it would augment the force? :-)

to demonstrate a force due to suction

there is no force in nature called "suction". none.

the link was posted last night. the guy who hijacked the professor's email
addy should have taken greater care in whose address he grabbed, for it would
seem the real professor at MIT would have long ago known of the demo that any
student -- or his mother or even little sisten in grade school -- could walk up
to and push the button to see for himself.
