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.
