Chimney Draw With Water
To illustrate the concept of chimney draw due to the Bernoulli effect.
Flask of colored water, plastic tube, compressed air source.
This is the principle of an atomizer, such as those which squirt a fine mist of perfume.
A plastic tube is inserted into a water reservoir, and a jet of air blown across the top of the tube. Water rises in the tube due to the reduced pressure in the moving air jet. Note that the cork in the picture is NOT sealed, so atmospheric pressure acts on the surface of the water in the beaker.◙
