How to make a rainbow?
What could be more beautiful and fantastic rainbow? Only a rainbow created by own hands. The easiest way to make a rainbow is to let the light through a prism. But the prism is not always at hand, but I really want to experiment with a rainbow.
There are several ways to make a rainbow at home from improvised means, let's look at a few of them.
Rainbow from disk
This is a very simple way to get a rainbow from an object that almost every household today has - a compact disc. The disc will suit any CD \ DVD \ Blueray enough to reflect sunlight from it and a beautiful rainbow will play on the white wall.
Rainbow from the water
To do this, let the light through the water. For example, you can put a glass of water on a window sill on a sunny day and the light passing through the water will create a rainbow. If this does not work, you can take a mirror and put it in a glass of water and try to reflect the sunlight on it.
You can also take a flat shallow container and at an angle put a mirror in it so thatso that one half was above the water and reflect sunlight on a white surface. A rainbow will immediately appear. The greater the capacity with water and the mirror, the greater the rainbow.
If the sky is clouded with clouds and the sun does not shine at all, a rainbow can be made the same way using a flashlight. But such a rainbow will not be so bright, so you have to close the curtains tightly and then begin to experiment.
Well, if the sun shines brightly, there is another sure way to make a rainbow. But for him to have to go outside and find a hose connected to the tap with water. It now remains to pinch the end of the hose so that the water comes out of it finely sprayed, and send it up to the sun. A rainbow will play in the spray of water.
