How does a Rainbow Form?

A rainbow forms when it is raining and the sun is out too. For example, if you do a project and get the materials: water, a crystal, and a light. First of all you have to put the crystal in the sun so the light can hit the crystal. then you are going to get a bowl of water and put it by the sun too. The bowl has to be in front of the sun and then the crystal after it. Then the light reflects the rainbow and that os how a rainbow forms if you do an experiment.
       The real rainbow is similar to the experiment you are doing, but a little different. When it rains, you can see the raindrops falling. Rainbows form when sunlight and rain combine in a specific way. When the drops fall down, the sun rays reflect on it and then the colors begin to show. Then when the rainbow shows the rainbow forms. It is similar to the experiment you would do, but in a bigger way.
         When the rainbow forms it needs sunlight and water to form. Well the sun is combined with different colors, but you can't see them. The rainbow also forms because if the sun hits the water drops in a certain angle, the colors start to show and the rainbow is formed. this is why we see the rainbow and how it forms. Also the colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet. This was how a rainbow forms.
