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.
Oobleck and other pressure-dependent substances (such as Silly Putty and quicksand) are not liquids such as water or oil. They are known as non-Newtonian fluids. This substance's funny name comes from a Dr. Seuss book called Bartholomew and the Oobleck. Materials. â¢ 1 cup of water. â¢ 1 to 2 cups of cornstarch. â¢ Mixing bowl. â¢ Food coloring (optional).
