title: Bernoulli Principle
aka: Venturi Tube  (really)

  Air is blown through the horizontal tube which changes cross section.  Increase flow of air until 6 to 8 inches of pressure is indicated on the manometers.
  Adjust the string to show the original level of the manometers with no pressure difference.

The "atomizer" or sprayer is an example, as would be a perfume bottle or a straw in a glass of water when blow across.

    Would this work on the moon? (ie. with lower gravity?)
