The rainbow maker will make a great gift for both kids & adults. Simply attach it to any window that receives direct sunlight & its solar powered mechanism will rotate the genuine Swarovski crystal, reflecting coloured light around the room & creating the appearance of beautiful rainbows & spectrums. Designed by David Dear, it has colourful cogs & mechanisms visible inside the transparent casing, so you can see the wheels in motion. The rainbow maker is very easy to install, as it has a suction cup hanger. It is ideal for Feng Shui enthusiasts, as the Rainbow Maker is meant to bring good Chi into your home.
