3A Science experiments

This experience serves has to relax For this experience(experiment) it is necessary: -1 1/2 cups water -1 tsp borax -4 oz. glue (clear glue works best) -food colouring -Glitter -Product has lens -shaving cream First of all it is necessary to take a bowl then to pay some water Then we put some borax to thicken the slime We mix the water and the borax… After that we resume a bowl to pay some glue by mixing her with the foam shaved We add some soap in the form of foam moss then mix the set before to have put everything in the same bowl we add der the cream and to finish of food coloring agents for customized your slime We add the lense product so that the whole is assembled. There are no difficulties reproduced a slime everybody can make him. The slime can be useful in the medicine for the people under stress, it is an anti-relaxing one.

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.

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

1- Why is this experience or invention useful ?  This experience can be used to create a dough which is magnetic. This experience is distressful. 2- Materials or products used ? The products used in this video are white glue, some of water, Borax powder and Iron filings. 3- What are the different steps to succeed this experience ? First step is putting on a bowl a full bottle of white glue. Then you mix it with a little bit of water and a teespoon of Borax powder to make the mixture fluffy.  After this, you mix the all and the slime is finished. The last step is putting into it Iron filings and the slime  will suddently be attracted by the magnet. 4- What are the various difficulties met through this experience? The difficulties are the dosage. If you put more or less water or white glue or more Borax powder to make the slime, it will not work and the slime will not be good and fluffy. It might be too much liquid. The slime could be dangerous too if you are allergic
