Bernoulli'S Principle - Thin Metal Sheets
Purpose
To demonstrate Bernoulli's principle and a model of the vocal cords.
Equipment
Mounted aluminum sheets, as photographed.

Description
Blow down between the thin sheets. The sheets pull together due to the low pressure caused by the high velocity of the airstream, according to Bernoulli's principle. When the sheets close, air pressure builds up, opening them and restarting the periodic cycle. This is suggested by many knowledgable persons as a model of how the vocal folds function.◙
