It seems that modern children are no surprise. New-fashioned gadgets, toys with many functions are different from those that their parents had in their childhood, like a modern boat from a wooden boat.
But lately, parents are increasingly paying attention to what this or that game gives in terms of development. Some of them allow you to explore the world, developing children mentally and physically.
And if in addition such a game can be doneindependently with the participation of the child, it is a huge plus. On 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 liquid at home and what do you need for this?
What is non-newtonian fluid
Before turning to the answer to the question: "How to make a non-Newtonian liquid at home with your own hands?" - it would not be superfluous to understand what it is and how it works.
Non-Newtonian fluid is a kind ofsubstance, which at different speeds of mechanical action on it behaves differently. If the rate of external influence on her is small, then she shows signs of a normal liquid. And if you act on it with a higher speed, then it is similar in signs to a solid body.
The advantages of such an entertaining game include:
- The possibility and simplicity of self-production.
- Low cost and availability of ingredients.
- Educational opportunities for children.
- Environmental friendliness (unlike some plastic games, does not contain harmful substances, and the composition is known to you in advance).
Entertainment and learning
What could be better than sharing a lesson withchild 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 liquid at home allows you to create interesting entertainment in just a couple of minutes. The result is a game that will enthrall the whole family. In addition, it develops hand motor skills in children.
If a non-Newtonian fluid quickly hit,then it will behave like a solid body, and you will feel its elasticity. If you slowly lower your hand into it, then it will not meet any obstacle, and there will be a feeling that it is water.
Another positive side is the developmentimagination. With different types of effects on the fluid, it behaves very interesting. If you put a container with it on a vibrating surface or simply shake it quickly, then it begins to take on very unusual forms.
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 liquid body.
How to make a 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 quite simple. It has only two main ingredients - water and starch. The last ingredient can be both corn and potato. Water should be cold. Everything mixes thoroughly. All is ready!
For a more liquid state of the mixture, the proportion of water and starch is 1: 1. For more solid - 1: 2. If desired, you can add food dyes, then the mixture will be bright.
And how to make a non-Newtonian fluid in homeconditions without starch? This recipe is a little 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 connected water with a small amount of borax. After that, both formulations are mixed and thoroughly mixed.
Both methods allow to obtain a non-Newtonian fluid, but the first one is much simpler and enjoys the greatest popularity.
More water and starch ...
Knowing how to make non-newtonian fluid inat home, it is possible, having increased the proportions, to make a sufficient amount of such a mixture and to fill it with, for example, a small children's pool. Depths of 15-25 centimeters will be enough. Then on the surface of this fluid, you can jump, run, dance without falling. But if you stop, then immediately immersed in it. This is a great entertainment for adults and children.
In Malaysia, a non-Newtonian fluid was flooded with an entire pool. This place immediately became very popular. People of all ages are having fun there.
