Which Slime Recipe To Use?

We have several basic slime recipes that can all be used for this green slime recipe. You decide which one works best for you depending on what slime activator you want to use. This allows for some flexibility depending on where you live in the world! Not everyone has access to the same ingredients!

Each of the basic slime recipes below have the full step by step photos, directions, and even videos to help you along the way!

Here we use our Saline Solution Slime  recipe. Slime with saline solution is one of our favorite slime recipes! We make it ALL the time because it is so quick and easy to whip up. Four simple ingredients {one is water} are all you need. Add color, glitter, sequins, and then you are done!

Where do I buy saline solution?

We pick up our saline solution in the grocery store! You can also find it on Amazon, Walmart, Target, and even at your pharmacy.

Now if you don’t want to use saline solution, you can absolutely test out one of our other basic recipes using liquid starch or borax powder. We have tested all these recipes with equal success!

NOTE: We have found that Elmer’s specialty glues tend to be a bit stickier than Elmer’s regular clear or white glue, and so for this type of glue we always prefer our 2 ingredient basic glitter slime recipe.

The Science Behind Slime

What’s the slime science all about? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. This is called cross-linking!

The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…

You add the borate ions to the mixture,  and it then starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Slime is a polymer.

Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like the clump of spaghetti!

Is slime a liquid or solid?

We call it a Non-Newtonian fluid because it’s a little bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?

Did you know that slime aligns with the Next Generation Science Standards (NGSS)?

It does and that means you can use slime making activities to explore states of matter and its interactions. Find out more below…

St Patrick’s Day Green Slime Recipe


  • 1/2 cup Clear PVA School Glue
  • 1 tablespoon Saline Solution (must contain boric acid and sodium borate)
  • 1/2 cup of Water
  • 1/4-1/2 tsp Baking Soda
  • Glitter
  • Confetti
  • Gold Coins
  • Black Pots
  • Food coloring


STEP 1:  In a bowl mix 1/2 cup water and 1/2 cup of glue together to combine completely.

STEP 2: Now’s the time to add your green food coloring, and gold or green glitter! Remember when you add color to white glue, the color will be lighter. Use clear glue for jewel toned colors!

You can never add too much glitter! Mix the glitter, sequins and color into the glue and water mixture.

How to make St patricks Day slime recipe with saline solutionPin

STEP 3: Stir in 1/4- 1/2 tsp baking soda.

Baking soda helps to firm and form the slime. You can play around with how much you add but we prefer between 1/4 and 1/2 tsp per batch. You can experiment with your own ratios!

STEP 4: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of the bowl. This is exactly how much you will need with the Target Sensitive Eyes brand, but other brands may differ slightly!

If your slime still feels too sticky, you may need a few more drops of saline solution. As I mentioned above, start by squirting a few drops of the solution onto your hands and kneading your slime longer. You can always add but you can’t take away. Saline solution is preferred over contact solution.

STEP 5:  Start kneading your slime! It will appear stringy at first but just work it around with your hands and you will notice the consistency changes. You can also put it in a clean container and set it aside for 3 minutes, and you will also notice the change in consistency! 

SLIME TIP:   We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency. The trick with this slime is to put a few drops of the saline soluti9n onto your hands before picking up the slime.

You will love how easy and stretchy this green slime is to make, and play with too! Once you have your desired slime consistency, time to have fun! How big of a stretch can you get without your slime breaking?

  1. Hi. I’m doing a science fair and I want to do slime. My testable question is “ does sta-flo or tide affect the stickiness if slime affect it on different surfaces

  2. Hi,

    Thank you so much for the plethora of wonderful STEM/STEAM experiences for children that you have created. I have purchased many and look forward to the new information to come.
    As an Early Childhood Educator, teaching a group of 18 PreK children with my co-teacher, I am always striving to learn.

    However, I wanted to point out an error in spelling. In your St. Patrick’s Day STEM Pack, specifically the Green Carnation Challenge, the title is written “DIE A CARNATION GREEN CHALLENGE”. The word “die”, which means “of a person, animal, or plant, stops living” and should be spelled DYE, “a natural or synthetic substance used to add a color to or change the color of something”. I am assuming that this was a oversight, and I wanted to make sure you knew.

    Once again, thank you so much for all that you do. I really enjoy your effort to support the education of young children.
