“When you add the Alka-Seltzer, it reacts with the water to make tiny bubbles of carbon dioxide gas. These bubbles attach to the blobs of colored water (food colored water) and float to the top. When the bubbles pop at the top, the colored blobs drop to the bottom. When you apply heat to the mixture (flashlight), the heavier liquid (water) absorbs the heat and expands because it becomes less dense. Since the density of water and oil is similar the moment the water is heated, it becomes lighter than the oil and also causes the colored water blob to rise. It sometimes changes the shape of the bubbled-blobs from the Alka-Seltzer, making the shapes and colors prettier and different. When it cools, it drops back down. The Alka-Seltzer will ultimately finish, at which point you can put more Alka-Seltzer. You can also try a stronger light source for more heat to adjust the view. 16.
