In such a way that, the halve part of the glass shall rest on the table while the other part will tend to be off the table. This must be positioned is such a way that the sun shines directly through the water and onto the sheet of white paper placed on the floor.

Step 4. If you are using a flashlight, place the glass of water on the white piece of paper, and move the flashlight around until a rainbow appears on the piece of paper. Did you notice anything?
