@mywaterquality.ca: This video demonstrates how a small drop of oil behaves when placed on the surface of water. Instead of remaining concentrated, the oil quickly spreads outward into a thin layer due to differences in molecular structure and surface tension. Because oil does not mix with water, it stays on the surface and expands rapidly, covering a much larger area than expected. This simple demonstration helps viewers understand how oil spills can spread quickly in natural water systems and why surface behavior plays a critical role in environmental contamination. #Water #Pollution #Education #waterquality #Science
