  2. If you are using the paper-and-pencil option, use the pencil to draw four or five pictures of the test tube on the paper.
  3. Fill the cup partway with water and put a few drops of the food color in it. Swirl it around until it’s well mixed.
  4. Use the funnel to fill the test tube halfway with the colored water.
