Fill your room with a swirl of dazzling rainbows! Just apply the Rainbowmaker to any window using the handy clear suction cup. In direct sunlight, the solar cell mounted on top of the Rainbowmaker will cause the attached crystal to begin to rotate, casting fantastic displays of colorful light all about the room! Watch as the multicolored exposed gears turn the crystal and light up your room. Provides a nice aesthetic for any room, and great entertainment for kids. Enjoy endless rainbows at home with the Solar Powered Rainbowmaker!
