âOobleck,â named for the mysterious green substance described in the Dr. Seuss classic Bartholomew and the Oobleck, is a non-newtonian fluid meaning it doesnât follow Newtonâs laws of motion. A non-newtonian fluid (like oobleck or silly putty) has a different viscosity depending on the force applied. By contrast, newtonian fluids (like water) have a constant viscosity at a given temperature. No matter how fast you stir them they never get thicker or thinner. Oobleck is a mixture of cornstarch and water.
How to Make 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.
