Science Experiments How to Make Slime With Contact Solution

I have yet to meet a kid who isn't crazy for slime. We first made slime when my daughter was two. It was such a hit that we printed up the recipe (download it here) and I published it in my book, TinkerLab: A Hands-on Guide for Little Inventors.

TinkerLab has readers from all over the world, and I learned that not all of the ingredients in our original slime recipe can be found outside of the United States. So, I did some digging to find an incredible slime recipe that can be made with ingredients – worldwide.

Low and behold, I found a simple over-the-counter slime recipe, and it's amazing! My kids tested it, loved it, stretched it, played with it endlessly, packed it away in plastic baggies, and have continued to use it for over the past few weeks. Plus, glitter!

We've always used Elmer's school glue  for our slime (I stock gallons of it – no joke!), and it's no surprise that Elmer's is also behind the Glitter Glue in this Glitter Slime recipe. Not only is Elmer's a solid product that I trust for our crafting needs, but it's also affordable, making slime an economical activity that keeps on giving.

Here's how to make an easy GLITTER slime with just three ingredients…

Supplies for Glitter Slime

• Bottle of Elmer's Glitter Glue (6 oz.)
• 1.5 teaspoons (7.5 ml) baking soda – We are die-hard fans of Arm and Hammer Brand
• 1.5 teaspoons (7.5 ml) eye drops or saline solution (contact solution) with Boric Acid or Sodium Borate in the ingredients – We used Bausch and Lomb ReNu Contact Solution
• Spoon or spatula
• Mixing bowl

Steps for Glitter Slime

1. Empty the bottle of glitter glue into a mixing bowl
2. Stir in the baking soda. Mix well.
3. Add contact solution and mix until slime forms. You'll notice it comes together immediately, and takes a few minutes to fully form.
4. Knead the slime with your hands to get it to a consistency you're happy with.

The Science Behind the Slime

Contact solution contains boric acid which is a disinfectant that keeps the eyes fungus-free. This makes contact lens wearer's eyes super happy. School glue contains polyvinyl alcohol (also known as PVA)which is made up of ethylene, oxygen, and acetic acid (from vinegar).

Here's how it the slime comes together: The polyvinyl alcohol molecules (found in the glue) and boric acid (found in the contact solution) combine and stick together. As they combine they make a polymer chain, which is the slime!
