Create a stunning oil and water density tower that visually demonstrates the concept of density using simple household materials.

Pour 1 cup of water into the clear container.
Add a few drops of food coloring to the water and stir well.
Slowly pour 1/2 cup of vegetable oil into the container. Observe how it floats on top of the water.
Carefully add 1 tablespoon of salt to the water and watch as it sinks through the oil.
Observe the layers created by the different densities of the liquids.
