What is Oobleck?

Oobleck is a suspension of cornstarch and water that can behave like a solid or a liquid depending on how much pressure you apply. Try to grab some in your hand and it will form a solid ball in your palm just until you release the pressure, then it will flow out between your fingers. Materials that behave this way are classified as non-Newtonian liquids because their flow properties are not described by a constant viscosity. The name Oobleck comes from the 1949 children’s book, Bartholomew and the Oobleck, by Dr. Seuss. In the story a sticky liquid falls from the sky as a result of the king becoming bored with normal weather.
