Underwater Fireworks

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water. Learners create the appearance of fireworks by adding drops of red, blue, and yellow food coloring to a cup of oil. Learners add this solution to a soda bottle nearly full with water and observe the bottle closely to witness diffusion in action.
