Here at The Franklin Institute we've done a number of Bernoulli exhibits in
one of our new exhibits.

My favorite is the Bernouli Bottle. We've taken the blower and put it at 45
degree angle intsead of blowing straight up and we float a water bottle
instead of a ball. The bottle actually floats upside down with the bottom
rounded like a ball. (The bottom needs to be heated and blown out)

We also have a bernoilli challange. It takes the classic device where you
blow air across the top of a vertical tubeand it raises the ball to the top.
  in this device visitors try to get a ball to float in the middle of the
tube rather than having it rise to the top by varying the pressure of the
ball floating over the top.
