DIY Slime

Updated: Jun 25, 2021

This easy slime recipe is a perfect introduction to slime for school-age children. With only three ingredients, children can practice measuring and combining ingredients in a recipe and modeling different shapes, all while making a gooey sensory activity! This recipe allows many opportunities for creativity, and can last for hours.


1 cup washable school glue (like Elmer’s)

1 teaspoon baking soda

2-3 tablespoons saline solution, food coloring (optional)

measuring spoons

mixing bowl

mixing spoon

airtight container for storage

Activity Steps:

Step 1: First, remember to prepare your workspace! While this is a fairly “clean” slime recipe, the materials can get messy so prepare an area to work and set out your materials.

Step 2: Once your materials are ready, you can start by pouring 1 cup of glue into your container. This is the part where you can add 1-2 drops of food coloring if you want to color your glue. You could even add glitter, pom pom balls, or other items to “decorate” your slime.

Tip: If you want glittery slime in the least messy way possible, substitute glitter glue for regular glue!

Adding color or glitter is optional.

Step 3: Next, add 1 teaspoon of baking soda to the glue, and mix until smooth.

Step 4: Then, measure out 2 tablespoons of saline solution and add this to the glue/baking soda mixture. The mixture should become harder to mix, and might be stringy! Continue to mix, until a ball of slime forms.

Step 5: Once you have a ball of slime in your container, take it out and begin to knead (squeeze, mix by hand) the slime with your two hands. If your slime is particularly slimy or does not seem to be combining, add ½ tablespoon of saline solution as needed. The slime should become mixed completely together and take shape.

Step 6: Once mixed, the slime can be played with or stored in an airtight container or plastic zip bag for future use!

Step 7: Clean up! Set your slime to the side and remember to clean your materials (like measuring spoons and mixing spoons) as soon as possible! The slime is made from glue, so it will harden and become hard to clean. Soak materials in soap and water for easy cleanup.
