What is the science behind the Oobleck?

Oobleck is a suspension of starch in water. The phenomenon is called shear thickening and it basically means particles in a dense suspension resist further compression in the direction of shear. When oobleck is at rest, the high surface tension of water causes water droplets to surround the starch granules.

Does oobleck have any uses?

Thus, the application provides a system of temporarily fixing potholes by filling them with bags of oobleck (or other non-Newtonian fluids). When the bag is placed in the pothole, the oobleck has time to act like a fluid and fill the hole.
