Bring nature bathing indoors with the Rainbow Maker and immerse yourself in a swirl of small rainbows. Visible light is only part of a rainbow though. Infrared radiation exists just beyond visible red light, while ultraviolet is just beyond violet. There are also radio waves, x-rays, and gamma radiation. Wonderful for children's rooms or to keep pets entertained, the Rainbow Maker casts delicate rainbows through a Swarovsky crystal that rotates using a solar powered motor.
