  • Food Coloring

  2. Fill the rest of the bottle with water, leaving about an inch from the top. 5ae04c887881

  3. Now, it’s time to add about 10 drops of food coloring. You and your friend will love this part! It’s awesome to see the way the food coloring stays in droplet form while it moves through the oil and only mixes when it hits the water at the bottom. aff2897581e8

  4. Break up the Alka Seltzer® tablet into several pieces (about 4) and have your friend drop them into the solution one at a time. (Don’t put them in all at once) Watch what happens! You can repeat the activity with other bottles, using different colored food coloring.
