Re: [Phys-l] question about Bernoulli



Lay the same sheet of paper on a table (near the edge) and blow across the paper - nothing happens. Now place the paper on a metal frame that support the sheet at many places so it's flat but has plenty of open surface below it. Now blow across the flat paper - nothing happens - no lift.

How about these examples:
Blowing across the top of a strip of paper held against your
lower lip.
