In this Family video tutorial you will learn how to make a lava lamp as a cool science experiment for kids. For this project you will need food coloring, water, vegetable oil and antacid pills. Take a bottle and fill quarter of the bottle with water. Fill up the rest of the space with oil. The water and oil will remain separate. Now drop food coloring in to the bottle. Each color will behave differently. For example, green settles at the bottom, yellow stays in the middle, red dissolves right away. Now put the antacid pills and the food colors will go up and down. You can put the lid and store it for later use.
