Some thing we've noticed when interviewing young visitors playing at our Bernoulli blower, (which has several foam shapes, you explore which one will float on the air current.) The kids tell us that the round ball is floating because the hose the air is coming out of is round. They said if the hose shape was square the air would be square and the square shape would float.
I wondered if this is a common misconception. If so it might be something you can turn into an exhibit.

        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?
