To make slime, mix a white glue, such as Elmer's, with water and borax. To customize the slime, you can add food coloring to the mixture to create colorful versions.
- Prepare the components
Slime is mixed in two stages. First, dissolve 1 teaspoon of borax in 1 cup of water, stirring well. In another bowl, mix 1/2 cup of water and 1/2 cup of glue, and add the food coloring if desired.
- Combine the mixtures
Add the glue mixture to the borax, and stir with a spoon to combine. Continue stirring until the mixture becomes difficult to stir. Move the slime into another bowl, and continue mixing by hand. Some water may remain in the first bowl.
- Work the slime
Continue working the mixture until it becomes flexible. The slime becomes firmer and more like putty the more it is handled. As it stiffens, slime can be molded and shaped, although it does lose its shape over time. The food coloring in the slime can stain, so use it only on protected surfaces if you have colored it.
- Store the slime
Slime sometimes evaporates or grows mold, so store it in a zip lock bag in the refrigerator to keep it fresh between uses.
