Materials needed: Bottle or Jar, Vegetable Oil, Water, Food Coloring, Alka-Seltzer Tablets
Instructions:
Fill 1/4 of the bottle with water.
Add any color food coloring. We did red to look like lava and then made a blue one.
Fill the rest of the bottle with Vegetable Oil.
Allow it to settle for about five minutes.
The water and oil should be completely separated with the oil on top. The bottles should look something like this. For the red bottle I ran out of Vegetable Oil, you can fill them almost to the top.
