NARRATIVE
            Various devices which apply Bernoulli's principle are available. These are:

    Ping Pong ball floating on air.

    Cones which will be held in an inverted funnel by reduced pressure above.

    Two hanging balls which are forced together by reduced pressure from a stream of air between them.

    Large styrofoam balls supported by a stream of air.

    Atomizer made from a thistle tube inverted in a beaker of water. A spray of  water is forced from the tube when air is blown across the top. The same effect can be demonstrated with Puffed Rice and a plastic tube. This is perhaps a better method as the individual grains can be seen traveling up the plastic tube.

    Put a Ping Pong ball in a mailing tube and fling it across the room to show a "curve ball".

    Use a thread spool with a glass tube in the hole to pull up a paper disc.  Stabilize the disc with a straight pin.

    Balance the orange wing on the two pan balance. Blow compressed across the top of the wing and it will rise (not visibly) and reduce the apparent weight as indicated by the now unbalanced of the system.
