The Science behind it
Water and oil do not mix when you put them together in a bottle. Since water has a greater density, the water goes to the bottom of the bottle and the oil, which has a lower density, will float on top. When you add the Alka Seltzer, it releases bubbles of carbon dioxide gas that rise up to the top and carry colored water. The gas reaches the top and escapes from the bottle while the colored water falls back down. The Alka Seltzer causes this reaction because it contains citric acid and baking soda which react with water to form sodium citrate and carbon dioxide gas.
