Make a Rainbow

You Will Need :

1. A glass of water 
2. A sheet of white paper
3. A Sunny Day

Instructions :

1. Fill the glass almost to the top with water.

2. Place the glass so that it is half on and half off the edge of a table, and so that the sun shines directly through the water, onto a sheet of white paper on the floor.

3. Adjust the paper and the glass until a rainbow forms on the paper.

4. Light is made up of many colors, and when it passes through water, it is broken up into the other colors seen in a rainbow.
