Non-Newtonian fluid and interesting experiments with it

Physics is not only formulas and laboratory tests of incredible complexity, but also very exciting, and most importantly, easy-to-implement experiments.

Today I want to tell you and perform a series of experiments with the so-called non-Newtonian fluid.

What is non-Newtonian fluid

Before embarking on direct experiments, I want to literally say in a nutshell what a non-Newtonian liquid is.

So, a non-Newtonian fluid is a fluid in the course of which its own viscosity depends on the velocity gradient. In most cases, such liquids have a highly heterogeneous molecular structure.

We will consider the simplest and therefore the most visual experience, and create a non-Newtonian liquid from ordinary starch and water.

And let us check the postulate, which says: the more rapid the external influence on the binder macromolecules suspended in the liquid, the greater the viscosity of the liquid.

Well, now let's move on from the necessary digression to experiments.

What is needed for the experiment

So, in order to create a non-Newtonian fluid you will need:

1. Starch. Absolutely anything that can be found in your kitchen or on the shelves of the nearest store will do.

2. Any loose container. I personally used a large plastic container.

3. Various devices for the experiment. I prepared a hammer and a Soviet meat grinder (you will learn what it is for from the video). Personally, you can pick up whatever your heart desires.

After everything is prepared, you can start preparing the liquid.

Conducting an experiment and preparing a non-Newtonian fluid

To prepare the liquid, pour starch into the prepared container and begin to gradually add water, while not forgetting to mix it all.

Thus, you should get a mixture with a consistency similar to liquid sour cream.

You can see the whole cooking process and very exciting experiences in the video below:

As you can see, non-Newtonian fluid is a fun and very simple experiment. If you liked the material and want to see even more experiments with a similar liquid, then rate both the article and the video with a like and write comments.

Thus, I will understand that the topic is interesting and will release a sequel in the shortest possible time.
