Slime Time

July 26, 2017
By Robert and Libby Strong and Richard Pollack - SMART Science , OVParent

Have you recently made slime? While there's currently an uptick in slime-preneurs on the internet, here at the SMART-Center, we have made different kinds of slime for many years.

The most common has been the borax and glue slime recipe. Recent concerns about using borax are likely due to how the slime was used rather than its ingredients, but some alternative recipes also work well.

In most of the recipes, however, sodium borate is the ingredient that causes the glue-based slime to form. The chemical, found in borax as well as contact-lens solution, causes the glue polymer to "cross-link" and form a more rigid substance than the original glue.

Remember that making slime is actually a chemistry activity and you should always have adult supervision. The adults should make sure you either wear gloves or wash hands thoroughly after playing with your slime. When you dissolve some materials and stir, googles also should be worn to avoid splashing in your eyes.

EXPERIMENT

In the photo on page 10, shaving cream and hand lotion were added to the slime in addition to the food coloring.

If you want to experiment with your slime, take the basic recipe and add some shaving cream to one half and lotion to the other.

What changes do you notice? Does it affect the texture or the stretch of the slime? What does the addition of both shaving cream and lotion do to the original slime mixture?

Have fun with slime, and remember to be safe and wash your hands after playing with your concoctions!

SLIME RECIPE

To make a basic recipe of what is considered a safe slime, you will need:

125 ml (1/2 cup) of Elmer's Washable Non Toxic Clear Glue or White Glue

125 ml (1/2 cup) of liquid starch

125 ml (1/2 cup) of water

Measuring cup

2 bowls and a spoon

Food coloring

In one of the bowls, mix the glue and water together. Add food coloring if desired. Several drops will be needed. Stir with a spoon until the glue and water are thoroughly mixed.

Pour the liquid starch into the glue and water mixture. Stir with a spoon and then with your hands. Be sure to wash your hands after handling slime.

Work with the slime on a covered surface. Wipe up spills right away to avoid damaging surfaces After you finish playing with your slime, cover it loosely and it will be fine for the next day.
