DIY your own creepy slime for Halloween

What makes science fun?  Well, we’d say making slime is certainly on that list.

You know that too, if you’ve tried out our recipe for making slime.

Now it’s time to tweak that a bit, and make some seasonally-appropriate, Halloween slime!

Here’s the stuff you need:

  • ½ cup white glue (like Elmer’s).
  • 1 squirt of foaming shaving cream.
  • 2 pumps of foaming hand soap.
  • 3 pumps of hand lotion.
  • Borax (in powdered form, which you can usually find in a grocery or hardware store).
  • And your Halloween ingredients:  Some BRIGHT orange food coloring or some glow-in-the=dark face paint (You choose.  Unless you want to use orange glow-in-the-dark paint and have it all.)

Here’s what you do:

  • Pour the ½ cup of glue into a bowl (not a fancy bowl).
  • Add the squirt of shaving cream, the two pumps of soap and the 3 pumps of lotion.
  • Mix well.
  • Add that orange food coloring (or that glow-in-the-dark paint).
  • Mix some more.
  • In a separate bowl, mix (also well) equal amounts of borax and water (try a half-cup each to start).
  • SLOWLY pour the borax solution into the first bowl while you mix with your fingers until it feels like…slime.  Halloween slime!

More of a visual learner?  You can see how to do it, by watching Slime 101.

And if you’d like a little science with your slime, you can read that right here from the scientific explainers at Valero:

“Slime is what we call a non-Newtonian fluid, meaning it has things that make it both a liquid and a solid.  The glue in the slime is a large chain of molecules called a polymer.  When we add the borax solution, it changes the structure of the chain making the slime thicker, which then allows us to twist, twirl and manipulate our awesome slime.”

If that word “polymer” sounds familiar, by the way, it’s because polymers are made from petrochemicals (which are made from petroleum and natural gas) and are used to make all sorts of things we use every day — from our cars and our phones, to our sweatshirts and our shoes.

Luckily, while all slime is made from polymers, not all polymers turn into slime.

Happy Halloween!
