How does a rainbow form? I bet you have wondered that before. I always use to wonder why there was a rainbow and how it was created. I was asked that question so many times before by little children. The problem is I did not know how to answer then, in fact I did not even know the answer. Now, I do though. Rainbows can only be formed when there is water or rain. Alos there has to be enough of the  sunlight so that it can show.  So rainbows form when  water particles or rain drops act as prisms. 
         The sunlight then hits them, and then magic happens. When those raindrops or water particles are prisms and the sunlight  gets to them, they refract all the colors of ROY G. BIV. You see since the water particles or raindrops are transparent the light colors are bended and all the colors start to appear. That is when a rainbow forms. Rainbows are usually visible after it has rained or even in your back yard when you put the hose in front of the sun.
