Making slime can be a fun afternoon activity or an interesting science project. No matter why children are making it, they always seem to have a good time. There are several different recipes for slime, so a child could give them all a try.
For the very young the first introduction to slime may be cornstarch slime. It is a simple mixture of cornstarch, water and food coloring.
Recipe:
*2 cups cornstarch
*1 cup water
*food coloring (optional)
*sauce pan
*large bowl
Heat the water in the sauce pan. It does not need to boil. It just needs to be warmed. This will make the cornstarch easier to work with.
Pour the warm water in a bowl and add food coloring. There are no rules for the color of slime, so let the children use their favorite. Make the water at least one shade darker than the desired end result.
Add the cornstarch to the colored water. It should be added slowly and the best way to blend it is to use your fingers. It should be a smooth, thick slime. If the texture does not feel right play with the amounts of water and cornstarch.
~ Borax and glue slime
Supplies:
*1/2 cup white school glue
*1/2 teaspoon Borax
*water
*glass bowl (resist staining)
*spoons
*glass jar
Mix 1/2 cup of white glue and 1 cup of water in the bowl. Use a spoon because glue is sticky.
If food coloring is desired add it to the glue mix mixture once it has been blended.
In the jar mix 1/2 teaspoon of Borax to 1/2 cup of water.
Gradually add the Borax solution to the glue mixture, stirring constantly.
Chocolate slime
Children need to be old enough to distinguish between slime that can be eaten and slime that is not healthy.
Over low heat combine 14-ounce can of sweetened condensed milk, 2 tablespoons chocolate syrup, 1-1/2 tablespoons cornstarch. Stir and heat until it is thick and creamy.
Remove from heat and allow to cool.
All of these recipes can be stored in plastic bags in the refrigerator and be warmed to room temperature and be used again.
No matter the reason for the slime, is always a great project. If it used as a science project then the chemistry behind the slime has to be revealed. It is all about polymers and how they react.
