Mark Liked His Tree Straight Up with a Twist

Mark likes his martinis dry, but never his Christmas trees. To avoid his tree turning into kindling prematurely, he created an automatic watering device that keeps it fresh and helps it last longer. His system pumps water from a 1-gal reservoir via a pump powered by a 12V dc power supply. Level sensors maintain the water level and provide overflow control. To avoid the risk of soggy Christmas presents, he suggests testing the system for water leaks in advance of use.
