Oobleck, a word coined from the Dr. Seuss book "Bartholomew and the Oobleck," has contemporarily come to define the substance created from mixing cornstarch and water. This mixture is notable for its dilatant properties, and as an inexpensive and non-toxic Newtonian fluid. While seemingly liquid, under pressure, the substance reacts as a solid. Gentle treatment, however, will allow the material to remain in its fluid state. More simply put, this sh*t is crazy.
Watch this video tutorial and learn how to mix water and cornstarch to either conduct a simple experiment in Newtonian physics or to create a weird gooey quicksand to smear all over your action figures, or hey, maybe even a little bit of both.
