Crystal Fountains is the original name in Laminars for back yard entertainment. The laminar effect is a high-tech illusion. The water is so well controlled it creates a continuous glass-like rod of water that hits the water virtually sound-free and splash-free. When color-changing fiber optics are added, and connected to a high quality fiber optic illuminator, it produces breathtaking evening light shows. Spectacular in pools or spas and can be in-deck mounted or installed to shoot from a planter. In a low wind area these "water rods" can reach up to 6 feet high and can travel up to 10 feet across without breaking up. Maximum heights and distances may vary according to water quality and local conditions. Child safe when used as instructed.
