Recipe for Fun!
Fill the bottle or jar 1/4 full with water. Add enough vegetable oil so the liquid is near the top of the container. The oil and water should separate into two layers, water at the bottom and oil on top. Once the liquids separate, add 6 - 8 drops of food coloring. Then add 1/2 an Alka Seltzer tablet and watch the bubbles form. Add more Alka Seltzer bit by bit to keep the bubbles rising and falling.
