Innovating Science® - Surface Tension of Water

Explain the principle of high surface tension as water acts like a membrane stretched across the surface preventing the sulfur particles from sinking. A wetting agent lowers the surface tension and allows the particles to fall through the surface to the bottom of the beaker.
