Solar Powered Rainbow Maker with Swarovski Crystal

Rainbows occur when sunlight —including all the wavelengths of visible light, which together appear as white light — pinballs in and out of water droplets. Now you can have that phenomenon in your home on any sunny day with the Rainbow Maker. Stick it in a window that receives direct sunlight and watch as the crystal rotates and refracts the incoming window light into marvelous swirling rainbows all over the room.
