How To Make A Rainbow

A rainbow is basically an arc of spectral colors, which is distinctly identified as red, orange, yellow, green, blue, indigo and violet. The red color can be seen on the outer part of the arch, while violet on the inner part of the arch. Usually a rainbow is seen just after a rain shower. These colors appear in the sky opposite to the sun, due to the refractive dispersion of sunlight in drops of rain. A rainbow can be caused by other forms of water as well, like mist, spray and dew, apart from rain. Children are really fascinated to see this phenomenon and eagerly wait for the rain. However, you can bring that smile on your child’s face by making a rainbow in the interiors of your house as well. If you wish to know how to make or build a rainbow, read on further.
