The Science of Slime

Slime is simply a collection of flexible polymer chains. Polymer chains are a long chain of molecules that have a repeating pattern of small units.

Glue is a polymer on its own, but when the activator ingredient is added (in this case laundry starch) it makes the polymer thicker and stretchier.

Slime making can be a wonderful introduction to chemistry, if children are allowed to experiment with things they think might make slime and are shown the chemical bonding patterns of the ingredients.

If you’re teaching younger kids, just tell them that slime is formed when the molecules in glue and starch cross link, creating stronger bonds.

What you’ll need to make fall leaf slime:

  • Elmer’s clear glue
  • Liquid laundry starch
  • Orange food coloring
  • Gold glitter
  • Fabric fall leaves

Why is My Slime Sticky?

Sticky slime usually means you don’t have enough activator. Try adding a bit more.

If that doens’t work, you may need to add something dry, like cornstarch, to help reduce how sticky your slime is. I like to add either cornstarch or shaving cream to eliminate stickiness.

Why is My Slime Watery?

Watery slime usually means you messed up the ratio, but it’s usually completely fixable. If your slime is too watery, try this:

  1. Add more activator. It could be you just didn’t add enough activator!
  2. Pour off excess liquid. It could be that you added too much water or activator and need to pour off some access.

If that doesn’t work, try adding a bit more glue.

We usually use clear glue because it produces a more consistent slime than white glue.

Add a squeeze of orange food coloring and a sprinkle of gold glitter to the slime before mixing.

Add the starch and mix. With clear glue, you don’t have to let the mixture set as long, but a few minutes is still helpful.

Stretch and work the slime to make it stretchier.
