An artificial waterfall is provided to secure the same effect like as a real waterfall by dropping the water from a predetermined spot of the artificial waterfall and to generate oxygen and anion in falling the water down. A model of the artificial waterfall is formed by using artificial rock materials made of styrofoam. A first paint like a water paint, a water bond, and plaster is applied on the styrofoam to prevent the styrofoam from getting rusty. A second waterproof paint is applied on an artificial styrofoam rock to prevent the water from soaking through styrofoam pieces. An adhesive bond and connecting pins connect a plurality of styrofoam panels. The water falls down along the artificial waterfall with one underwater pump(14). |
