When I was in fourth grade I had to do a presentation in front of the class on anything I wanted. I got my presentation idea from this book, 50 Simple Things You Can Do to Save the Earth. I conducted my presentation on how to conserve toilet water without replacing the toilet. The process is very simple: you fill an empty milk jug with some rocks and water, (to give it some weight) and place it in your toilet tank. The milk jug is displacing the water so the toilet uses 1 gallon less water each time it is flushed.
