30. Bernoulli Demos

Several short demonstrations nicely illustrate Bernoulli's principle.

  1. Support a ping-pong ball or a bloop ball on an air stream from the building supply or a hand-held vacuum.
  2. Pick up a 3 X 5 card by blowing through a thimble at it.
  3. Blow up a Bernouli bag with one breath
  4. A Venturi tube sucks the air out and collapses a bottle.
  5. Blow between two pieces of suspended cardboard and they come together.
  6. Blow the roof off a house by directing an air stream from a vacuum cleaner over it.
  7. Demonstrate the breakdown of Bernoulli.
