How to make a non-Newtonian fluid at home: a recipe
It seems that modern children are no longer surprising. Modern gadgets, toys with many functions differ from those that their parents had as a child, like a modern boat from a wooden boat.
But recently, parents are increasingly paying attention to what gives in the development plan this or that game. Some of them allow you to explore the world, developing children mentally and physically.
And if in addition this game can be donealone with the participation of a child, then this is a huge plus. In the vastness of the Internet you can find many such toys. One of the most simple and interesting is the so-called non-Newtonian fluid. So how to make a non-Newtonian fluid at home and what is needed for this?
What is a non-Newtonian fluid
Before turning to the answer to the question: "How to make a non-Newtonian fluid at home with your own hands?" - it will not be superfluous to understand what it is and how it works.
Non-Newtonian fluid is a kind ofsubstance, which behaves differently at different speeds of mechanical action on it. If the speed of external influence on it is small, then it exhibits signs of ordinary liquid. And if it is acted upon at a higher speed, then it is similar in character to a solid.
The advantages of such an entertaining game include:
- Possibility and simplicity of self-manufacturing.
- Low cost and availability of ingredients.
- Cognitive opportunities for children.
- Ecological compatibility (unlike some plastic games, it does not contain harmful substances, and the composition is known to you beforehand).
Entertainment and training
What could be better than sharing witha child of something interesting and unusual? Moreover, this activity will be really useful not only for children, but also for adults. The simplicity of how to make a non-Newtonian fluid at home makes it possible to create interesting entertainment in just a couple of minutes. As a result, a game that will lead the whole family. In addition, she develops motor skills in children.
If you quickly hit a non-Newtonian fluid,then it will behave like a solid body, and you will feel its elasticity. If you slowly lower your hand into it, it will not encounter any obstacle, and there will be a feeling that it is water.
Another positive side is developmentimagination. With different types of effects on the liquid, it behaves very interestingly. If the container with it is put on a vibrating surface or just shaken quickly, it begins to take very unusual shapes.
Do not forget about the educational benefits. Such a liquid allows in practice to study the simplest foundations of physics - the properties of a solid and a liquid body.
How to make a non-Newtonian fluid at home: two ways
The composition of the mixture directly affects its properties. Therefore, one should know how to make a non-Newtonian fluid at home. The recipe is very simple. It has only two main ingredients - water and starch. The last ingredient can be either corn or potato. Water should be cold. Everything is thoroughly mixed. All is ready!
For a more liquid state of the mixture, take the proportion of water and starch 1: 1. For a more solid - 1: 2. If desired, you can add food colors to it, then the mixture will be bright.
And how to make a non-Newtonian fluid in the homeconditions without starch? This recipe is a little more complicated, but it is just as effective as the previous one. First, water and conventional PVA glue are mixed in the proportions of 0.75: 1. Separately, water is connected with a small amount of borax. After that, both compounds are mixed and thoroughly mixed.
Both methods make it possible to obtain a non-Newtonian fluid, but the former is much simpler and more popular.
More water and starch ...
Knowing how to make a non-Newtonian fluid inat home, you can increase the proportion, make a sufficient amount of such a mixture and fill it with, for example, a small children's pool. Depths of 15-25 centimeters will be enough. Then on the surface of this liquid you can jump, run, dance, without falling through. But if you stop, then immediately plunge into it. This is great entertainment for adults and children.
In Malaysia, a non-Newtonian liquid was flooded with a whole pool. This place immediately became very popular. People of all ages have fun there.
