Edible water bubbles


1-Why is  this experience or invention useful ? What is its usefulness ?
It’s useful because this invention can replace the water bottle so save the material like plastic, it’s more ecologic
2-What are the materials or products used ?
The products used are sodium alginate and calcium chloride but for the experience that replaces calcium chloride with calcium lactate, resulting in a membrane that is less tough.
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?
BEFORE YOU WILL NEED :
 - 1 g of sodium alginate (a natural substance derived from brown seaweed)
- 5 g of food-grade calcium lactate (a type of salt that can be found commonly in cheese and gum)
- A bowl filled with 1 cup of drinking water
- Another bowl

FIRST STEP : You have to Add 1 g of sodium alginate to 1 cup of water. Then use an immersion blender to dissolve the sodium alginate. Once you're confident that it's dissolved, set the mixture aside to get rid of any air bubbles that may have formed during blending.
SECOND STEP : You have to Add 5 g of calcium lactate to 4 cups of water and mix well using a spoon.
THIRD STEP : You have to scoop up some of your sodium alginate solution using a deep spoon. Very carefully plop the sodium alginate into the calcium lactate bath. Repeat with the remaining sodium alginate but do not crowd the bath.
FOURTH STEP : You have to stir the sodium alginate bubbles very gently for 3 minutes.

FIFTH STEP : You have to STEP 5: After 3 minutes, remove the "bottles" from the calcium lactate bath using a slotted spoon and transfer them to a water bath to stop the reaction. 
 4- What are the various difficulties met to achieve the experiment ?
The difficulties are the materials can be found but sometimes they are scarce and  you must be meticulous. Also you must get a suitable bag to transport them because bubbles are delicate.
5- In which fields can we use this experiment? ( Industry, medical field, sports field, environment, everyday life…).

We can use it for the environment to stop using plastic bottle and save some money on the making of plastic bottles. So it’s sustainable.

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

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
