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