Oobleck Recipe

### Oobleck Recipe 🌈🔬 **A Fascinating Non-Newtonian Fluid: The History of Oobleck** Oobleck, a non-Newtonian fluid named after a substance in the Dr. Seuss book "Bartholomew and the Oobleck," has captured the imagination of children and adults alike since its discovery. The concept of non-Newtonian fluids, which behave differently under stress compared to conventional liquids, has been studied by scientists for centuries. Oobleck, made from a simple mixture of cornstarch and water, exhibits properties of both a liquid and a solid depending on the force applied to it. Its mesmerizing behavior, often described as "shear-thickening," has led to its popularity as a fun and educational science experiment. **Instructions** 1. **Gather the Ingredients 🌽:** - You'll need 2 cups of cornstarch and 1 cup of water. Optional: food coloring for colorful oobleck. 2. **Mix the Ingredients 🥄:** - In a large mixing bowl, combine the cornstarch and water. Stir until the mixture is smooth and well blended. If desired, add a few drops of food coloring to create vibrant oobleck. 3. **Experiment with Texture and Consistency 🌀:** - Adjust the ratio of cornstarch to water to achieve the desired texture. If the oobleck is too runny, add more cornstarch. If it's too thick, add more water gradually until you reach the desired consistency. 4. **Observe the Properties 🧪:** - Explore the fascinating behavior of oobleck by running your fingers through it slowly and then quickly. Notice how it behaves like a liquid when poured slowly, but becomes firm and solid when force is applied rapidly.
