Superspray by Cody Stauffer-MacDowell

Cody Stauffer-MacDowell. Contrived. Super Spray. This picture demonstrates water pressure. Water pressure inside the hose forces water to move through the hose and out the open end. Leaving the end completely open allows a large volume of water to escape at the same time. The water can slowly pass through this opening because the water is only under limited pressure. Reducing the size of the opening causes the water to leave the hose with much more force. This same amount of water has to leave the hose, but now it has a much smaller area to pass through. The water has to move at much higher velocities to deal with this decrease in area. This increase in velocity allows the water to be sprayed out of the hose to reach great distances. This principle is shown in the picture as the thumb covers part of the opening and forces the water to leave the hose at a high velocity causing the spray.
