Learn air compression cloud in a bottle

1-Why is this experience or invention useful? What is its usefulness? This experience is useless for us. This experiment just serves to discover how the air is compressed.

2-What are the materials or products used? We just need a bottle and our hands.

3- What do you have to do to achieve the experience? Can you describe precisely the different steps to achieve the experience or the invention? For this experiment we need a bottle and take it normally and then turn it 8 times in the middle of the bottle then open the cap and a smoke (compressed air) comes out.
 
 
4- What are the various difficulties met to achieve the experiment? The difficulty here is to turn the bottle but once we have made a turn it is much easier.

5- In which fields can we use this experiment? (Industry, medical field, sports field, environment, everyday life…). Compressed air can be used to inflate a tire, stripping a paint surface: breathe under water.

6- Explain the reasons why you chose this experiment and why it appealed to you?
This experience is interesting, useful it and very easy for kids.

Magic snow

We have choose this experience named magic snow, it’s useful because it can absorb water and created Magic snow. We can reverse the process just by adding salt. This product can absorb 200 or 300 his weight of water on magic snow. To do this experiment the products used are water and sodium polyacrylate (you can obtain from disposable diapers or buy in a garden center) and salt. The differents steps for created magic snow are to put polyacrylate sodium on water and the result will be on few seconds. After this we can at any moment reverse the process just by adding salt The only difficulty met to achieve the experiment is to find sodium polyacrylate but this experiment can be used in everyday life if we have to absorb too much water or keep it. We have chosen this experiment because it is useful and it’s used on few products like diapers or to add viscosity and thicken some products for example in cosmectics. But we think than it can be more used by people in everyday l
