This is the sprinkler that casts a color-changing spray, transforming a lawn into an effervescent water and light show. As water flows through the sprinkler it propels a turbine generator that powers the color changing LEDs and pressurizes the water, producing a 6 1/2` high by 19 1/3` wide plume of fine mist that seamlessly transitions from red to blue to green to yellow to purple. This looks like such a fun item to have in the backyard. I have not seen a sprinkler like this and makes mine look super boring!
