Homemade Slime

I remember making homemade slime at the Maryland State Fair one year. It was an educational demo about plastics. I was already in my twenties, but it was still fun to play with slime! Research for work, right? I took the recipe back to the school where I was working at the time, and they loved it.

Homemade Slime Recipe

This is a polymer which is a long chain of molecules. You need to blend two solutions together to create the polymer reaction. First, the glue solution:

  • 1 Tbsp Elmer's glue (white glue makes opaque slime, clear makes translucent -- both are very pretty!)
  • 3 Tbsp water
  • Add food coloring if desired or a little Glow in the Dark Paint if you want glow-in-the-dark slime

And then mix the Borax solution:

Slowly mix the two brews together and agitate it to form the polymers. This could mean squishing them in a plastic bag or stirring with your hand in a tub outside.

In these photos, the white slime is made with Elmer's washable white school glue while the red slime and blue slime are made with Elmer's washable clear school glue so the colors appear translucent.

 It's not very messy once the polymers have formed. Here you can see the white is totally mixed up and the red and blue are still very runny around the edges. A little more mixing and stirring with the hand and it holds together more.

We added a couple of sprinkles of glitter to the slime after it was formed. At least it won't end up all over the house when it's stuck in slime!

We put the patriotic slime into sandwich bags for a homemade birthday present for a friend who was turning 5 years old. He loved it!

This putty will keep for a very long time if you store it in a container that seals well. It becomes harder as it dries out.

Non-Toxic Goop

For something safer for the youngest children yet still fun for older ones, slowly mix water into cornstarch in a bowl. Add food coloring if desired. It feels hard if you touch it quickly and liquid if you touch it slowly! Roll a ball in your hands and watch it melt.

This is a good outside activity. It will leave an easily washable powder on clothes.
