Sprinklers water your yard and provide enjoyment and excitement for children. The wide variety of styles and designs of sprinklers are ever-changing. There are basic sprinklers that spray water in one direction only; rotating sprinklers rotate and spray up and down as well. Some sprinklers come equipped with timers which will automatically turn on and off at scheduled times throughout the day and night. Some sprinklers also provide optional spray patterns, such as mist and fountain features, for additional creativity. You can purchase sprinklers for as little as $5 or as much as $100 online, depending on the style and the features of the sprinkler.
