Disappearing Water Fountain If you love the gushing sound of a fountain but are less crazy about having an open pool of water in your yard (especially if you have children), this decorative rock fountain may be for you. A disappearing fountain gives you the spray and sound of water, without the open pond. It can be a pretty cool visual effect, as the water will disappear into your base. The smaller water basin makes for a greener solution, requiring less water. This can be a good choice if you have children or pets that you don't want to worry about falling into a pond, and don't care about having plants or fish.
