  1. From you research create a chart of densities among various household liquids. Use the following: water, honey, vegetable oil, and rubbing alcohol. Find more liquids in your home but have an adult make sure it is safe to mix with other liquids.
  2. Based on your chart what has the greatest density? List the liquids in order of decreasing density.
  3. Now you will start building your layers. From your list (most dense to least dense) start pouring the liquids into the glass.
  4. Measure ¼ cup of each liquid and carefully pour the liquid in the center of the glass. Do not pour the liquid down the sides of the glass.
  5. Continue pouring the layers in the center of the glass. The liquids may mix while pouring. Wait a few minutes for the layers to separate before pouring the next layer.
  6. You can add food coloring to the liquids to see the layers better.
