Final Answer:
What I did: I poured water into a glass and added blue food coloring to make it look like the sky. Then I added oil on top to show how oil floats on water.
What I saw: The blue water stayed at the bottom, and the oil floated on top without mixing. When I stirred, they mixed for a moment but separated again quickly.
What I learned from this experiment: Water and oil don’t mix because oil is less dense than water. This is why oil floats on top of water, just like in the atmosphere where different layers of air can stay separate based on their density.
