It seems that modern children are no longer surprised. New-fashioned gadgets, toys with many functions are different from those of their parents in childhood, like a modern boat from a wooden boat.
But recently, parents are paying more and more attention to what this or that game gives in terms of development. Some of them allow you to learn the world, developing children mentally and physically.
And if in addition such a game can be made independently with the participation of the child, then this is a huge plus. On the Internet you can find many such toys. One of the simplest and most interesting is the so-called non-Newtonian fluid. So how to make non-Newtonian fluid at home and what is needed for this?
What is a non-Newtonian fluid
Before proceeding 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 of substance that behaves differently at different speeds of mechanical action on it. If the speed of external influence on it is small, then it shows signs of ordinary liquid. And if you act on it with a higher speed, then it is similar in features to a solid.
The advantages of such an entertaining game include:
- The possibility and simplicity of self-manufacturing.
- Low cost and availability of ingredients.
- Cognitive opportunities for children.
- Environmental friendliness (unlike some plastic games, does not contain harmful substances, and you know the composition in advance).
Entertainment and Learning
What could be better than sharing something interesting and unusual with a child? Moreover, this lesson will be really useful not only for children, but also for adults. The simplicity of how to make non-Newtonian fluid at home allows you to create interesting entertainment in just a couple of minutes. The result is a game that captivates the whole family. In addition, she develops motor skills in children.
If you quickly hit a non-Newtonian fluid , it will behave like a solid, and you will feel its elasticity. If you slowly lower your hand into it, then it will not meet any obstacle, and you will feel that it is water.
Another positive side is the development of imagination. With various types of effects on the liquid, it behaves very interestingly. If you place the container with it on a vibrating surface or simply shake it quickly, then it begins to take very unusual forms.
Do not forget about the educational benefits. Such a liquid allows one to study in practice the simplest fundamentals of physics — the properties of a solid and a liquid body.
How to make non-Newtonian fluid at home: two ways
The composition of the mixture directly affects its properties. Thus, you 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, the proportion of water and starch is taken 1: 1. For harder - 1: 2. If desired, food colors can be added to it, then the mixture will be bright.
And how to make non-Newtonian fluid at home without starch? This recipe is a bit more complicated, but just as effective as the previous one. First, water and ordinary PVA glue are mixed in proportions of 0.75: 1. Separately, water is combined with a small amount of borax. After that, both compositions are mixed and thoroughly mixed.
Both methods make it possible to obtain a non-Newtonian fluid, but the first is much simpler and is most popular.
More water and starch ...
Knowing how to make a non-Newtonian fluid at home, you can, by increasing the proportions, 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 you can jump, run, dance on the surface of this liquid 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 fluid was flooded with a whole pool. This place immediately became very popular. People of all ages have fun there.
