Colorful Fall Leaves Slime
This fall leaf slime was inspired by the brilliant reds, oranges, and yellows of autumn leaves. Clear slime works especially well because the glitter and leaf confetti shine through.
It’s an easy seasonal twist on our favorite homemade slime recipes.
Supplies
- 1/2 cup clear washable school glue
- 1/2 cup water
- 1/2 teaspoon baking soda
- 1 tablespoon saline solution
- Food coloring
- Glitter
- Leaf confetti
- Mixing bowl
- Spoon
- Measuring cups
- Reusable container for storage
Important: Check that your saline solution lists sodium borate and/or boric acid in the ingredients. These ingredients help activate the slime.
How to Make Fall Slime
STEP 1: Add 1/2 cup of clear washable school glue to a mixing bowl.
STEP 2: Pour in 1/2 cup of water and stir well.
STEP 3: Add your food coloring, glitter, and fall leaf confetti.
Try red, orange, yellow, or gold for classic fall colors.
STEP 4: Stir in 1/2 teaspoon of baking soda.
STEP 5: Add 1 tablespoon of saline solution and stir until the slime begins to form and pulls away from the sides of the bowl.
Knead the slime with your hands until it reaches your desired consistency. If the slime still feels sticky, add just a few drops of saline solution to your hands and continue kneading.
💡 Tip: Add activator slowly. You can always add a little more, but adding too much can make slime rubbery.
Why Does Slime Work?
Slime is a fun way to explore a little chemistry while you play.
School glue contains long chains of molecules called polymers. When the glue combines with a slime activator containing borate ions, those polymer chains begin connecting.
Instead of behaving like a runny liquid, the mixture becomes stretchy, squishy slime.
