Slime is one of the playthings that kids never get bored with. Playing with this highly viscous, gooey substance is indeed a fun thing to pass time. The original product sold in the market was green in color. Today, there are many variants of it, which differ in color and constituent ingredients. No doubt, you will get a plethora of slime toys, sold in nearly all toy centers. But, it is more fun to make it at home with simple ingredients from the kitchen counter.

How to Make It?

While making slime, a base ingredient is polyvinyl alcohol. Another alternative that serves the same purpose as polyvinyl alcohol is a long chain polysaccharide.
Borax, chemically known as sodium tetraborate, is used for cross-linking the polymer and giving it that rubbery texture. This boron compound is not toxic, but causes skin irritation to a sensitive skin and also, has side effects when ingested. So, borax is not preferred for use in kid's activities.
