Surf's Up

Question: What happens when water is mixed with oil?

Hypothesis:

A. The oil and water will mix and change color.

B. The oil and water will become cloudy.
C. The oil and water will separate.
D. The oil and water will form a solid.

Conclusion: The water and oil separate!  Why?  Oil is lighter (LESS DENSE) thans water and will not mix with it.  The water and oil will separate and when gently rocked back and forth will look like a "wave" in the jar!
