MUNDANE MYSTERIES: How does quicksand form?

You may have seen this crazy story last week in Milford where two women noticed some quicksand as they were walking on Walnut Beach.

That got me thinking, how does quicksand even form?

via wikipedia:

Quicksand is a colloid consisting of fine granular material (such as sand, silt or clay) and water. Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight.
