When your kids keep ask you “where is the rainbow”, I bet this is a tough question to be answered. How do you describe the “refraction and reflection theory” to the 6 years old kids?  Instead of describe of it, I would be easier to show them the rainbow. I know it is hard too, but whit this Rainbow projector clock, things get easy.

Like the name suggests, the rainbow projector clock project a beautiful rainbow across your wall, or even in your room’s ceiling. You can choose from three different modes – Variation, Slow and Vivid. The three cycles will involve the rainbow fading in from red to purple, color by color gradually, before it fades out from red to purple once again. What more, the rainbow is appear in order, so your kids can learn the right order as well visually.
