First you should know that osmosis is a phenomenon of diffusion of matter characterized by the passage of solvent molecules from one solution to another through the semi-permeable membrane

1)The sugar solution is more concentrated than water because it contains dissolved sugar molecules. The dissolved molecules can not pass through the semi-permeable membrane but the water molecules can. So the purpose of the experiment was that the egg in the sweet mixture shrinks and in the water that the egg absorbs the liquid so that it is larger.

2) To do this experience you have to take :
- 2 eggs         -something to heat (cooktop)
- water           - a pan
- 1 glasses    - spoon
- 1 bowl
- vinegar

3) I can'  say that the experiment was successful because I broke one of the two eggs,  but I can deduce that the egg absorbs water with the semi-permeable membrane. (Picture at the bottom).

4) I really liked to do this experience because I always wanted to do it and I was really curious. This experience was really famous in social media so it was a good time for me to try. I liked that the egg has several aspects.

It was the egg that was in the sugar solution I put it in the water we can see that it has grown.

when I put the vinegar icecube in the bowl

after adding baking soda

# data[].attributes.body
For this experiment, I poured in a first tupperware water and vinegar (purple) and in a second one vinegar (orange) . Then, I freeze for three hours.
In two bowls, I poured 1 cup of water and on tea spoon of baking soda.
After this, I put the vinegar icecube in a first bowl. I saw bubbles, I added baking soda and water and I saw more bubbles.
I put the water and inegar icecube in the second bowl. I saw less bubbles than the first one. And I did the same things. However, I took out the icecube of the water and I put some baking soda I saw the food coloring going out.

I poured lemon juice and baking soda into a bottle and the balloon inflated.
Lemon juice can be replaced with vinegar.

With this experiment, I am now able to know which materials are good absorbers and which are not.

What I used:
-sagar cubes
-plate
-water
-food colouring
-aluminium foil
-cling film
-paper

First of all, I needed to add a few drop of food colouring (I didn’t have it in my house so I used some sirup, this is why the color is not so vivid) in a plate with water in it. Then I built 3 stacks of sugar cubes. Each one has a material on the top of one cube( (like a sheet of foil, a cling film and a piece of paper). Afterwards, I put them on the plate at the same moment and I waited for the first stack to fall.  It has been found that the one with the aluminium foil collapsed first just before the stack with the the paper. 10 minutes after that the one with the cling film fall.

I have to make some colourful backing soda ice cubes and watch them fizz as I add vinegar.

The recipe to create an eruption

I mix vinegar and baking soda. There is a chemical reaction which produces a gas witch exerces pressure because the liquide overflows.

-1 for this experiment, I removed the eggshell of 2 eggs with vinegar and left it on for 24hours.
One of the 2 eggs broke so so i continue the experiment but I will not be able to compare with my own egg so I will look at the original experiment.
-2 Then i made a dissolution of sugar in water. I have to wait until the solution is cold. I put the egg in it and I have to wait 24h.
