“The balloon represents the lung and the plastic sheet across the bottom of the bottle represents the diaphragm muscle.  As you pull the tab down, you contract the diaphragm and inflate the lung.  As you push the tab back up, the diaphragm relaxes and the lung deflates.  It is a subtle inflate/deflate with the balloon, but the girls were able to see the basic idea of how the diaphragm and lungs work.”
