The Honey of the Fall
This photograph exhibits honey spilling into water. The honey is denser than the water. When it hits the water it begins to coil as it falls, accumulating at the bottom.

Water Striders and Surface Tension
Water, due to its hydrogen bonds and polarity, has high surface tension. The water striders are able to stand on the water because the surface tension allows them to stay on top of the water without breaking the surface tension. The water around the water strider in the back was treated with soap. Soap, a surfactant breaks the surface tension of the water and the water strider is unable to stand. It still floats, however, because the bug is less dense than the water.
