10. Color Fireworks
For this activity, you already have all the things you need in your kitchen. You need water, oil, and food coloring to make fireworks in a jar. Fill 3/4of the jar with warm water. In a separate bowl, mix 3 or 4 tablespoons of oil with several drops of different colors. Gently mix the oil and colors and then slowly pour into the jar. Since oil is less dense than water, colors from oil will sink and then start to mix with other colors creating wonderful fireworks of colors.
