Full Answer

This experiment requires a plastic bottle, vegetable oil, water, food coloring and an effervescing antacid tablet.

Step 1: Combine oil and water

Start with a plastic bottle and fill it about 2 inches from the base with water, then fill most of the bottle with oil.

Step 2: Add color

Add a few drops of food coloring. These will not disperse until reaching the water at the bottom of the bottle.

Step 3: Introduce the antacid tablet

Drop the effervescing antacid tablet into the bottle and watch it descend to the water. There, as it dissolves, it will release bubbles of colored water into the vegetable oil. Shining a flashlight through the bottle can enhance the lava lamp effect.
