How To Make A Rainbow In A Bottle

There are many magical tales about rainbows such as finding a pot of gold at the end of a rainbow. Children often draw pictures of these beautiful colors in the sky in the shape of an arch over the land. Rainbows are usually made after a good hard rain with the reappearance of the sun. When the light and water combine, different colors are reflected. You don't have to wait for a hard rain to see the colors in a rainbow. You can make a rainbow with a bottle and water.

Step 1

Pour water in the glass bottle until it is full. Screw the cap on tightly.

Step 2

Place your glass bottle directly in the sunlight on a window sill or a table that you can place something underneath it.

Step 3

Move the bottle so it hangs over the window sill or table without falling to the ground.

Step 4

Put the white construction paper on the floor, underneath the part of the bottle hanging over the table.

Step 5

Check the white paper for rainbow colors. If there are no colors, move the bottle around a little until you see a rainbow reflected on the white construction paper. You may choose to copy the rainbow colors on the construction paper with the watercolor paints and brush.
