choose three different colors of food coloring, and measure one teaspoon of each color into its own cup (each cup will have one color in it). stir the mixture in each cup with the fork (wipe it off between colors) until the food coloring is well mixed.
put layers of newspaper under the aluminum pan to catch any water that splashes. fill the pan with water, but not all the way to the top. pour a little bit of one colored oil mixture onto one area of the pan. then repeat this with the other two colors, on different areas of the pan. what happens? why do you think this occurs?
