Demonstrating a Rain Shadow

• Take a hose with a spray attachment and spray water at one side of a short wall.
• 2/3 of the water should fall on the hose side of the wall.
• The other 1/3 will fly over the top of the wall.
• Close to the wall on the side away from the hose will stay dry because the water is shooting far over the wall.
• The dry area is just like a rain shadow.
