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:
- Pour the cornflour into the mixing bowl.
- Add water to the bowl and stir until the mixture is smooth.
- Keep mixing until the mixture thickens and becomes difficult to stir.
- 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.
- 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:
- Pour 1 cup of cornflour into a mixing bowl.
- Add 1/2 cup of water to the bowl.
- Stir the mixture until it’s smooth.
- Keep stirring until the mixture thickens and becomes difficult to stir.
- Try to squeeze the mixture in your hand. It should feel solid when you apply pressure and liquid when you release it.
- 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.

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.
