Borax Slime Ingredients

Making slime at home or in the classroom is a fun activity for adults and children. Homemade slime is a polymer, which means it has molecules that can be stretched and twisted to take on the shape of containers and molds. When you are not playing with your slime, you can put it in a sealed plastic bag for storage.


Water from your faucet is the first ingredient you will use to make Borax slime. You will fill one 8-oz. disposable plastic cup with room temperature water.


Borax, or sodium tetraborate, is a multi-purpose cleaning agent and the second ingredient you need to make slime. It is a naturally occurring mineral made of sodium, boron, oxygen and water. Add 1 tsp. of Borax to the 8-oz. glass of water and stir it until it is dissolved. This is set aside and not used again until the last step after you add food coloring. Take 1 tbsp. of this solution and add it to the glue cup.


Glue is the third ingredient you need when you make slime. You need a standard white glue like the type children use in school. Pour glue into a separate 8-oz. plastic cup until it is 1 inch deep. Add 3 tbsp. water into the glue cup.

Food Coloring

Food coloring is used to customize your slime. You will need to use liquid food coloring. Add a 2 to 3 drops of any color to the cup with the glue in it. Experiment with mixing different colors in a separate bowl before you add the drops of food coloring to your glue cup.
