Non-Newtonian fluids are fascinating substances that act in unique ways. They can resist deformation, flow slowly, or even behave like a solid when pressure is applied to them. One way to create non-Newtonian fluids is by using cornflour. In this article, we’ll show you how to make non-Newtonian fluid with cornflour and answer some of the most frequently asked questions.

Description

Non-Newtonian fluids are substances that don’t follow the rules of Newtonian physics. They can’t be defined by a single viscosity because their viscosity changes depending on the shear rate or stress applied to them. In simple terms, non-Newtonian fluids don’t behave like normal liquids. They can be solid-like or liquid-like, depending on the force applied to them. Some common examples of non-Newtonian fluids include ketchup, honey, and even quicksand.

How to Make Non-Newtonian Fluid with Cornflour

To make non-Newtonian fluid with cornflour, you’ll need the following supplies:

• 1 cup of cornflour
• 1/2 cup of water
• A mixing bowl
• A spoon or whisk

Follow these steps to make the non-Newtonian fluid:

1. Pour the cornflour into the mixing bowl.
2. Add water to the bowl and stir until the mixture is smooth.
3. Keep mixing until the mixture thickens and becomes difficult to stir.
4. Once the mixture is thick, try to squeeze it in your hand. You should feel the substance become solid when you apply pressure, but liquid when you release it.
5. If the mixture is too thick, add more water. If it’s too thin, add more cornflour.

That’s it! You’ve successfully created non-Newtonian fluid with cornflour.

Step by Step

Here’s a step-by-step guide to making non-Newtonian fluid with cornflour:

1. Pour 1 cup of cornflour into a mixing bowl.
2. Add 1/2 cup of water to the bowl.
3. Stir the mixture until it’s smooth.
4. Keep stirring until the mixture thickens and becomes difficult to stir.
5. Try to squeeze the mixture in your hand. It should feel solid when you apply pressure and liquid when you release it.
6. If the mixture is too thick, add more water. If it’s too thin, add more cornflour.

Tips

Here are some tips to help you create the best non-Newtonian fluid with cornflour:

• Use warm water to make the mixture. It will help the cornflour dissolve faster and create a smoother mixture.
• Don’t add too much water at once. Add it slowly and stir continuously to avoid creating lumps in the mixture.
• Experiment with different ratios of cornflour and water to create different consistencies of non-Newtonian fluids.
• Use food coloring to make the mixture more visually appealing.

FAQ

Hair Care

While this article is about making non-Newtonian fluid with cornflour, it’s important to note that cornflour is also great for hair care. It can be used as a dry shampoo to absorb excess oil from the scalp and hair. Simply sprinkle some cornflour onto your scalp and massage it in. Let it sit for a few minutes, then brush it out. Cornflour can also be used to create a natural hairspray by mixing it with water and essential oils.
